Description
Technical field
The present invention relates to data processing field, and be particularly related to demonstration and the installation of portlets (portlet) on client platform.
Background technology
WWW (World Wide Web) is the multimedia information retrieval system of internet.In the web environment, client machine uses HTTP(Hypertext Transport Protocol) and web server to communicate.The web server uses the SPDL that is called HTML(Hypertext Markup Language) to provide the visit such as the file of text, figure, image, sound, video etc. as the user.HTML basic document format is provided and has allowed the developer to specify be called hyperlink, being connected to other servers and file.In the example of internet, the network path that arrives server is by URL(uniform resource locator) (URL) sign, and URL has the special grammer that is used for the define grid connection.So-called web browser, for example Netscape Navigator (Netscape Navigator is the registered trademark of Netscape Communications Corporation) or MicrosoftInternet Explorer (Microsoft and Internet Explorer are the trade marks of Microsoft), they are application programs of moving on client machine, make that the user can be by visiting information and navigating between different html pages with the URL designated links.
When the user of web browser selected a link, client machine sent request to name service (naming service), so that host name (in URL) is mapped as the residing particular network IP of server machine (Internet protocol) address.The name service is returned can be in response to the IP address of described request.Use described IP address, the web server is established to the connection of server machine.If server machine can be used, then it returns the web page.In order to assist the further navigation in website, the web page generally includes one or more being called " anchor point (anchor) " or the hypertext of " link " is quoted (hypertext reference, " HREF ").
Door (portal) normally will compile and its web that is illustrated in the door web page will be used from the content of various separate sources, and may have the content that the complicated personality feature comes to provide for the user customization.Portal application can provide gateway for one or more backend software applications, and often is provided on the independent portal server.
Portal server is the portal page that comprises one or more portlets (portlet) with the web content arrangement usually.Portlets is the web assembly, and by the portlets Container Management, the dynamic web content is handled and produced to portlets.Door can with this content of often being called as fragment (fragment) with from the content aggregation of other portlets together, thereby form portal page.According to user's configuration of portlets, the content that is produced by portlets may be different for different user.
Door provides navigate frame (navigation framework) for the web page set by the level arrangement on the server.This framework provides and has allowed the user interface of navigation by the system of the obtainable page on the server.Provide the user interface of this navigation to be called theme (theme).Each page can comprise zero or more a plurality of portlets, and page arrangement pre-determines and makes up by using design or management tool.
Utilize the server-side portal of standard, use client web browser to check that several portlets compile output on the single page.The user causes the portlets operation to be received by door by for example submitting form to or following link and carry out reciprocation with the content that portlets produces.When portal server received the HTTP request, it determined that whether described request comprises with any portlets that is associated with portal page is the operation of target.If existing with the portlets is the operation of target, then described portal requests portlets container calls described portlets and handles described operation.Described portlets is handled described operation, and produces the contents fragment that will be included in the new portal page.In addition, being requested every other portlets on the portal page refreshes and contents fragment is delivered to described door.Described door is packaged in each portlets contents fragment in the portlets window, adds title and control knob for each window.Sometimes this is called as ' packing (wrap) ' each contents fragment that is provided, and the additional markers that is used for packing described fragment is called as ' skin '.Described skin can comprise control knob, described control knob can be used to for example portlets be placed the AD HOC as editor or configuration, perhaps the show state of portlets is changed into maximization or minimized visual state, just as what in common windows system, will see.Then, door compiles the portlets window and is complete portal page, so that send to client.The web browser presents described code on the display screen of client.
If the user is from the URL to the door homepage, perhaps pass through to the URL link beginning of specific webpage, perhaps pass through to the URL link beginning of the example of portlets, then can be by the navigate frame that provides by theme to the navigation of the page that provides by described door; Under latter event, described door provides the complete page that comprises this portlets.
A lot of companies have done huge investment and have satisfied its business need in the exploitation of portlets.At present, these are application of pure server side, have only the client of use web browser just addressable, and general only just addressable when the network by certain form is connected to portal server.For the user, can when not being connected to network, continue to use those identical portlets to be highly profitable.This can realize by those portlets being rewritten as for the stand-alone utility that is deployed in client-side.But this will require to revise all portlets and move as stand-alone utility to allow them, and this will be expensive and task consuming time, might hinder from the server migration to the client-side.The present invention is intended to address these problems.

Instrument is write the plug-in unit that the file in the Eclipse file space that is called as work space is in pairs operated, and for its UI in the worktable specific to instrument provide the surface.When starting the Eclipse platform, show the workbench window display page to the user, this page provides the Integrated Development Environment of being set up jointly by available plug set.Eclipse will move on various operating systems, comprise Linux
TMAnd Windows
TM(Micrisoft and Windows are the trade mark of Microsoft at the U.S., other countries and above-mentioned All Countries, and Linux is the trade mark of Linus Torvalds at the U.S., other countries and above-mentioned All Countries).
Described the Eclipse platform in the Eclipse platform technology summary of Object Technology International company, this for example can find at www.eclipse.org, and is comprised in here by reference.
The Eclipse platform comprises the add-on file folder, has wherein disposed each plug-in unit.Each plug-in unit all is installed in add-on file folder down in its oneself the file.Plug-in unit is described in and is called plugin.xml, is present in the XML inventory file in the add-on file folder and describes.Manifest file declares the interconnection of this plug-in unit to other plug-in units, and tell the Eclipse platform thing that it need be known in order to activate described plug-in unit.By plug-in registration Table A PI make resolved plug-in manifest file content the programming on available, and resolved plug-in unit standard be buffered in be called the plug-in registration table storer in the storage area in.
The Eclipse platform provides plug-in management kernel and some core inserter that is present in each Eclipse deployment.The identity of these core inserters is hard coded within the Eclipse platform, and described platform is known these plug-in units of activation in each running example of Eclipse.On the other hand, non-core plug-in unit is activated by other Plugin Requirements the time.
Interconnected model between the plug-in unit is very simple: plug-in unit statement any amount by named extension point, other plug-in units can have contribution to these extension points, and the expansion of described plug-in unit statement any amount, described plug-in unit is contributed one or more extension points to other plug-in units with described expansion.Drawing together the expansion of part can be expanded by other plug-in units.Extension point can have corresponding api interface.Other plug-in unit is contributed the enforcement of this interface to this extension point by these expansions.
The XML element and the attribute that use during as the appendix 1 definition plug-in unit that has been comprised in the Eclipse platform plug-in manifest canonical record here.Each plug-in unit all has unique identifier (XML attribute id), and described identifier is used to reference to the plug-in unit in the inventory file of other relevant plug-in unit.Described unique identifier also can use in the plug-in code that the supplier provides, so that the running example of visit plug-in unit.
Comprise two stages in that plug-in unit is installed on the Eclipse platform: the phase one comprises the peculiar file that is used for described plug-in unit under ' plug-in unit ' catalogue that the resource (inventory file, jar or war file and other resources) that will constitute plug-in unit copies to platform.Subordinate phase comprises by will be from the data of the inventory file of plug-in unit, and for example resolved plug-in unit standard is added the plug-in registration table to and registered described plug-in unit.In case this is finished, then when described plug-in unit was required to carry out certain function, described plug-in unit can be activated by the Eclipse platform.
Eclipse platform user interface (UI) example is based on view and perspective (perspective).View is the window that shows about the information of object; And perspective provide thereon can organize views display page or background (canvas).Plug-in unit can be given platform contribute views, and view can be organized into different perspectives.
The Eclipse worktable provides many extension points, comprises view extension point.By this view extension point, other plug-in units can be given platform with contribute views by one or more expansions being offered this extension point.
With reference to figure 1, show the simple case that shows client platform with three different perspective 102a, 102b, 102c.Perspective 102a is displayed on topmost, and comprises that 104: three views of 5 views show the portlets content, and two non-portlet view show other client platform components.Each shows that the view of portlets content is by the expansion contribution of portlet view plug-in unit as the Eclipse view extension point.To the method for portlet view being added to the Eclipse perspective be described after a while.
As already mentioned, at the internal operation of portal server, portal server compiles the content from all portlets on the page to portlets usually, and returns the content of being compiled.In the present invention, portal server is from the content of a portlets and the content aggregation of another portlets, but the web content that is provided by single portlets once is provided.Therefore, use term ' portlets server ' to indicate the portal server process of standard to be modified here.As used herein, the such server process of term ' portlets server ' expression, for example using when being requested, the agreement of HTTP provides marking document and any file that is associated and script from portlets.Can utilize single portlets server implementation the present invention.But,, have several de facto standards at present for writing portlets.Preferred embodiment is supported two (or more a plurality of), i.e. WebSphere in these standards
TMPortlets and Java
TMSpecification request (JSR)-168 standard.WebSphere is the registered trademark of the International Business Machines Corporation of New York Armonk.
Preferred embodiment uses the revision of Websphere portal server and the JSR-168 portal server small routine server that provides access.This server process provides the marking document from single portlets, that is, and not to compiling from the content of different portlets.Each portlets of URL addressing also returns the labeled fragment of this portlets separately.Portal server code is tailored, so that any theme or skin are not provided, perhaps carries out the packing of portlets contents fragment.Portal page is replaced by the Eclipse perspective, has the ability that the perspective among the Eclipse that crosses over the display page navigation is provided that changes, and the skin that is presented at the portlets contents fragment on the display page transfers to be provided by the portlet view tool that is implemented as the Eclipse platform plug-in, and this will illustrate below.
In addition, Tomcat application server code and Websphere and JSR-168 portal server code quilt be ' reduction ' as far as possible, so that do not comprise unnecessary function, the server security feature (login/authentication etc.) that for example in client computer system, is not required.
The portlets server is configured to the installation of small routine of providing access, and supports portlets life cycle (for example initialization, service and destroying method) and pattern to change.Initialization (Init) method allows portlets to be initialised; When requiring portlets to present its content, call method of servicing; And destroying method makes portlets can be withdrawed from service and is destroyed.
Preferred embodiment uses Tomcat Java
TMThe embedding version of 2 enterprise versions (J2EE) application server fits into young procedure service device.Tomcat is JavaServlet and the JavaServer Pages that develops under the Jakarta project of Apache software fund
TMOpening by source code of technology realizes (Java and all trade marks based on Java are the trade mark of Sun Microsystems, Inc. at the U.S., other countries or above-mentioned All Countries).In addition, the Tomcat application server provides the support to the J2EE service, and for example database connects and the JavaBean of enterprise (EJB).Other application server, for example the Websphere application server can be used equally well, it will be understood to those of skill in the art that this point.
Fig. 2 a shows interactive skeleton diagram between the system component according to preferred embodiment.Assembly comprises Tomcat application server 201 and application server interface (API) 205, the portlets server that is used for each portlets that will be supported, here be that Websphere goes into small routine server 204b and JSR-168 portlets server 204a, portlets interface 203a, 203b (they are implemented as the part of portlets server), with be installed in portlets server 204a on JSR-168 portlets 206 in a JSR-168 portlet view plug-in unit 202 that is associated, and by the web browser 207 of operation in the client view (not shown in Fig. 2 a) of portlet view plug-in unit 202 contribution.The web browser uses HTTP 208 to communicate by letter with Tomcat server 201.
Fig. 2 b shows the Eclipse plug-in architecture of preferred embodiment, and wherein, portlet view tool is used as the portlet view plug-in unit and provides.As shown, client 100 comprises a plurality of portlet view plug-in units 202 (showing 2) and project plug-in 110.Project plug-in comprises code, described code be used for the realization system and comprise a plurality of UI assemblies 220 and a plurality of server component 230 (although they are illustrated as forming single plug-in unit 110 at Fig. 2 b, but according to preference, they can be realized in a lot of independent plug-in units).UI assembly 220 comprises Setup Wizard 209, line instrument 215, has the standard portlet view 211 and the portal template 213 of UI Operation Processor (actionhandler) 212.When the view of the associated portlet of portlet view plug-in unit will be shown, each portlet view plug-in unit use standard portlet view code 211 with its portlets content packaging in view window, control icon, operation web browser etc. are provided.
The realization that portlets Setup Wizard assembly 209 provides portlets that menu and Setup Wizard are installed, Setup Wizard is created portlet view plug-in unit 202, will describe after a while.
Standard portlet view 211 provides each portlet view plug-in unit to realize the code that its view is required.This makes portlet view tool can be provided for the framework of portlet view (frame), control icon for the portlets that uses on view framework, and moves the web browser in each portlet view.UI Operation Processor 212 comprises code, clicks portlets control icon in response to the user and indicates control operation, and described code is carried out by portlet view tool.
Give and to be installed in each portlets on the client by Setup Wizard its oneself associated portlet view plug 202 is provided.Be installed on which portlets server and depend on the type of the portlets that is mounted by portlets interface expansion 214 problems with reference to which portlets interface 203a, b that guide provides about portlets, promptly it is JSR-168 or Websphere portlets.
The portlet view plug-in unit 202 on Fig. 2 b left side has launched, so that its content is shown, its content is two expansions: promptly be connected to the portlets interface expansion 214 of server and the view expansion 210 of expansion Eclipse view extension point by user-defined server extension point 232.View 210 normative reference portlet view 211, it obtains the required code of operation web browser 207 from standard portlet view 211.Web browser 207 can be used to receive the web content by HTTP from the portlets server, exists the associated portlet example of plug-in unit on the portlets server.Portlets interface expansion 214 comprises the access data that are used for this portlets server, and allows the associated portlet instance communications on view 210 and the relevant portal server.Portlets interface expansion 214 comprises the title and the id of its associated portlet, and comes with reference to relevant portlets interface 203 (a or b) with this.
Inner this content that shows of view window that the view plug of portlets uses the web browser to provide according to the configuration data of portlets at plug-in unit,
As shown in Fig. 2 c, client computer system 100 comprise a plurality of Eclipse of being inserted into platforms worktable extension point 222 UI expansion and be inserted into server expansion by the server extension point 232 of project plug-in 110 statements.
With reference to figure 2a and Fig. 2 b, process in the time of will describing the platform operation now.At first, the Eclipse platform starts; Read the inventory file of its registered plug-ins, set up its storer plug-in part registration table; And start the plug-in unit of its registration.Therefore, project plug-in 110 is activated, thereby can be used for the Eclipse platform.And described platform starts the portlets plug-in unit 202 of any registration.Any special event does not take place in portal server 204a, 204b, till user's demonstration comprises the page of portlet view or new portlets is installed.
When the user selected the perspective of the view that comprises portlets that will be shown, the plug-in unit that is associated must obtain the tag content of described portlets, and it calls so that search described content.At first, it calls the interface object that is used for this portlets type and checks whether relevant portlets server 204a, 204b start.If the portlets server does not also start, then portlets interface 203a, 203b tell application server 201 (by API 205) to start relevant portlets server 204a, 204b.When the portlets startup of server, its all portlets that are mounted 206 will be initialised.Comprise the parameter of its portlets example of being associated with of sign with operated portlets associated portlet view plug 202.Portlet view tool is created in the view window of wherein moving the web browser, and by server A PI the portlets example is inquired about, and described server A PI transmits the id of described portlets example and the pattern that is required.Portlets server Return URL and view are delivered to built-in browser 207 with it.Browser 207 sends to application server 201 by HTTP with the URL request, and receives the response that comprises the mark that is presented by described portlets.Then, browser 207 shows the portlets content according to the mark that receives.Portlets can cover the link of other pages, document etc., and if the user select in these any one, then the viewed device of the mark that is linked uses HTTP to search.
When user and portlets 206 reciprocations, the reciprocation between browser 207 and portlets server 204a or the 204b continues.By clicking on user in the skin of portlet view or the control icon in the window frame, start portlets pattern or state and change request, for example edit, dispose or the help pattern.Then, portlet view tool is carried out UI Operation Processor 212, and it notifies portlets interface 214 which control knob of operated view selected.Portlets interface 214 should ask the URL of fresh content to be delivered to the web browser from it on view.The web content that receives from this URL makes browser to show portlets 206 with requested pattern/state.
The installation of portlets is described intuitively referring now to Fig. 3 a, 3b and 3c.After platform 200 starts, will show welcome perspective, have control strip/button usually, for example can select the option of ' opening blank portal template ' from described control strip/button, as shown in Fig. 3 a.Blank portal template is a kind of instrument expansion 213 of extension point (is implemented as Eclipse UI ' perspective '), and it allows the user to create new perspective and use to be fit into young program guide (seeing Fig. 3 b) portlets is installed.Selection is fit into after the young program guide 209, shows the listed files 300 of portlets web application archive (.war) file in the particular file folder 302 of client 100 to the user.If the user selects one or more portlets from this tabulation, then the .war file of each selecteed portlets will be installed in (single .war file can comprise that a plurality of portlets and user can select the specific portlets in the single .war file to install) on the relevant portlets server by guide.When each selecteed portlets has been mounted, show successful Installation Report to the guiding user, then, depend on employed platform specific, the user may must restart client platform so that use the new portlets of installing.Guide also provides client platform view for the portlets that each is mounted, and will describe this mechanism in more detail after a while.Therefore, these views are added to the available views tabulation of platform, and described tabulation shows all views expansions, and developer or user can use the new display page of described tabulation design, for example new perspective.
With reference to figure 4a, in order to design new perspective, after 400 startups, show menu page (being implemented as the expansion of Eclipse UI extension point ' operational set (ActionSet) ') to the user, 402, the user can select and open blank portal template from described menu page.The user selects ' view is shown ' option from the drop-down menu of template, and in 404 tabulations that available portlet view and/or client platform components view be shown.406 select in the listed view one cause this view in current perspective by instantiation with open.The user adds more view can for the page that is created, and 410 can be by organizing view on the page, and can design the perspective of the view of view that non-portlets client platform components as shown in fig. 1 is shown and portlets such as the function such as reorientate of adjusting size, for example drag-put.412, the perspective of being created can be saved in the tabulation of predefined perspective, can call described perspective once more with similar mode when needed, so that switch to the page new in the door.When described perspective is closed, the view on the described perspective also will be closed.
With reference to figure 4b, when customer requirements shows the perspective of storage, 414, the perspective that the drop-down menu selection under ' opening perspective ' option is required.Then, 416, all have plug-in unit as the view of the part of selecteed perspective platform 200 instantiations, and read their inventory file.Information from inventory file is used portlet view tool to create framework and any necessary tool bar and menu for each view window at 418 platforms, and the web browser is embedded each by the portlet view of instantiation.For the view by the contribution of portlet view plug-in unit, each relevant plug-in unit is activated, and passes through the requests for content of embedded type web browser transmission to its associated portlet 420.Described request is gone to application server, application server is guided it into relevant portlets server (when doing this part thing, application server is determined correct container so that processes said request by checking described request URL and finding its container, the mapping table of for example portlets server).Then, show perspective 422 to the user, portlet view all illustrates the content that receives by the embedded type web browser arbitrarily.
Then, the user can with any one reciprocation in the shown view.If for example the user chains by the URL that shows in view and clicks and the portlet view reciprocation, then the embedded type web browser has the content of this URL from the portlets server requests by HTTP.The single portlets of URL addressing.The portlets server only returns the html content from the portlets that is addressed, and subsequently this content by the embedded type web browser display.View remaining on the perspective is not refreshed.
With reference to figure 5, will be described in now portlets will be installed to the functional steps that relates in the process on the application server.Provide portlets Setup Wizard assembly 209 to platform, described assembly provides user interface when 502 are selected by the user, and described user interface makes the user can select specific portlets war file from the war listed files.War (web application archive) file is the routine encapsulation of portlets.In response in the selection of 504 users to portlets, Setup Wizard 209 is determined the portlets type from the war file, and the example of establishment portlets interface 203, if relevant portlets server 204a, 204b are not initialised, then with its initialization.Setup Wizard 209 is installed portlets .war file 211 by portlets interface 203a, 203b instruction portlets server 204a, 204b, and this is at the 506 new examples that caused the portlets 206 on the portlets server.In this process, the portlets server is fit into young program file and adds the portlets details to the registration table of its portlets container, described its portlets of portlets Container Management.
After portlets .war file 211 successfully is installed, produce the new portlet view plug-in unit 202 that is associated with this portlets and comprises its oneself inventory file at 508 Setup Wizards 209.Described inventory file has been listed required display label (for example title of plug-in unit view), control and the expansion of view plug, and state two expansions: the view of Eclipse UI view extension point is expanded, with JSR-168 or WebSphere portlets interface expansion 214, JSR-168 or WebSphere portlets extension point 232 that portlets interface expansion 214 expansions are provided by project plug-in 110.The expansion of portlets interface makes portlets can state that it is associated with the portlets of which kind of type, and with reference to the code that is included among relevant portlets server component 204a, the 204b, so that relevant portlets server interface 203a, 203b is provided.When view will be displayed to the user, the standard portlet view code of view extended reference portlet view plug-in component operation.Use it, portlet view tool is created needed menu and tool bar, and will be applied to the framework of portlet view by the icon that instrument provides.In case to the registration of Eclipse platform, then as mentioned above, the user can add the view of new portlets to the Eclipse perspective at 510 portlet view plug-in units.
The difference of the arrangement of the portlets example of described arrangement and server-side portal is, the portal server 204 in the native system will be from the content aggregation of a plurality of portlets in portal page.On the contrary, each portlets has its oneself portlet view window, and described window can show on user's Eclipse platform screen.And portal server is not bundled to each portlets contents fragment in the portlets window, adds the framework that comprises title and control knob to each window.On the contrary, portlet view tool provides the framework of its portlet view window according to the portlet view plug-in manifest, comprises title bar and control knob.
