Control builds device (WebWidgetBuilder) and is realized by various dissimilar controls structure devices with the polymorphic form of interface, and encapsulation creates the HTML code of this control;
Input page builds device and builds the HTML code that assembly (WebPageBuilder) reception creates, and returns to the JSP page.
For generating output page aspect: than generating input page, generate output page aspect (bank-user is checked the result required function of this transaction) relatively simple, mainly contain and show and print the simple requirements such as voucher, the present invention has defined the output page and has addressed this problem specially.The output page is mainly built by output data model, and exports data model by Copybook, and frm is abstract, is a set of JAVA class of describing output picture and interface.Copybook data model has been expressed the semantic information of CPY file, describes front end system and IBM host data interface.Input page is had relatively high expectations to user's displaying, comprises the multimedia messagess such as picture, and therefore data volume is larger.The page generates and leaves in front end system server in advance, directly loads this JSP page when request preview.The process difference generating from input page is different, and the output page, because itself is without multimedia messages, just represents fraction transaction results information, and data volume is less, when therefore output page face generative process occurs in the operation that receives user's request.The build tool comprises: (1) builds the main control component (HoutputXmlBuilder) of the output page; (2) output data model builds assembly (HOutput); (3) resolver factory (FrmFactory); (4) output picture resolver (FrmDescParser); (5) output page builder structure assembly (HDeviceOutputXmlBuilder).
Fig. 8 is that in system of the present invention, service end 300 generates output page face process flow diagram, and known referring to Fig. 8, output page face product process is as follows:
Main control component (HoutputXmlBuilder) request that builds the output page generates output data model corresponding to output code;
Output data model builds assembly (HOutput) and obtains resolver factory (FrmFactory) according to output code;
Corresponding output device is searched by resolver factory (FrmFactory);
Output picture resolver (FrmDescParser) obtains and returns resolver to resolver factory (FrmFactory);
Resolver factory (FrmFactory) builds assembly (HOutput) to output data model and returns to output resolver;
Output data model builds assembly (HOutput) request and generates output data model;
Output picture resolver (FrmDescParser) is written into FRM resource file according to output code, resolves FRM resource, builds and return output data model;
Output page builder structure assembly (HDeviceOutputXmlBuilder) obtains output page makeup object from building the main control component (HoutputXmlBuilder) of the output page, generates xml code and generates output page XML.
In addition, for event semantics data module 316, for storing the data model of input picture event system, described event (Event) is exactly for certain specific assembly, triggered a series of actions causing by certain condition, also a set of JAVA data structure (referred to as event semantics data model) can be converted into, final executable JAVASCRIPT can be generated by this sets of data structure.Event semantics data model as shown in Figure 9, an event, inevitable associated some definite controls.The event that in service end, each assembly has an event queue (Event Queue) to preserve it to be associated with.An event includes one or more conditional branchings, and a conditional branching is made up of one or more conditional branching.Condition is combined by conditional operation function (Condition function) and logical operator.In Condition object, be used for storing these conditional operation function and logical operators with a list (List).Action command is actually a kind of function (Function) of any type, it and conditional operation function there is no substantive difference, different is that its rreturn value of conditional operation function can only be the Boolean of true or false, and action command function can return to any value (comprising void type).
3 statements are exactly 3 action commands below:
clear(fromengname)；
clear(uodwaive)；
nest_txn(118980)；
Event semantics data model is carried out the conversion of event in the process that produces jsp by page makeup (WebPageBuilder) assembly to the conversion of javascript.Following table has briefly been listed TPDL event type and Javascript event mapping relations:
