Device is realized, and encapsulates the HTML code for creating the control；
Input page composer structure component (WebPageBuilder) receives the HTML code created, returns to JSP.
In terms of the generation output page：Compared to generation input page, generation output page aspect (check by bank-user
The result required function of this transaction) it is relatively easy, mainly there are the simple requirements such as displaying and printing voucher, invention defines defeated
Page-out specially solves this problem.The page is exported mainly by output data model construction, and output data model by
Copybook, frm are abstract, are a set of JAVA classes of description output picture and interface.Copybook data models express
The semantic information of CPY files, description front end system and IBM host data interfaces.Input page is shown to user requires higher, bag
Containing multimedia messages such as pictures, therefore data volume is larger.The page previously generates and is stored in front end system server, asks preview
When be loaded directly into the JSP.From input page generation process difference unlike, export the page due to itself without
There are multimedia messages, simply show fraction transaction results information, data volume is smaller, therefore output page face generating process occurs
When receiving the operation of user's request.The build tool includes：(1) main control component of the structure output page
(HoutputXmlBuilder)；(2) output data model construction component (HOutput)；(3) resolver factory
(FrmFactory)；(4) picture resolver (FrmDescParser) is exported；(5) page builder construction component is exported
(HDeviceOutputXmlBuilder)。
Fig. 8 is the generation of service end 300 output page flow journey figure in present system, it can be seen from Fig. 8, the generation of output page face
Flow is as follows：
Output number corresponding to main control component (HoutputXmlBuilder) the request generation output code of the structure output page
According to model；
Output data model construction component (HOutput) obtains resolver factory (FrmFactory) according to output code；
Output equipment corresponding to resolver factory (FrmFactory) lookup；
Output picture resolver (FrmDescParser) obtains and returns to resolver to resolver factory
(FrmFactory)；
Resolver factory (FrmFactory) returns to output resolver to output data model construction component (HOutput)；
Output data model construction component (HOutput) request generation output data model；
Export picture resolver (FrmDescParser) and FRM resource files are loaded into according to output code, parse FRM resources, structure
Build and return to output data model；
Export main control of the page builder construction component (HDeviceOutputXmlBuilder) from the structure output page
Component (HoutputXmlBuilder) obtains output page makeup object, generates xml code and generates output page XML.
In addition, for event semantics data module 316, for storing the data model of event system in input picture, institute
It is exactly for some specific component to state event (Event), a series of actions as caused by triggering certain condition, can also be changed
Into a set of JAVA data structures (referred to as event semantics data model), it can generate what finally be can perform by this sets of data structure
JAVASCRIPT.Event semantics data model necessarily associates the control of some determination as shown in figure 9, an event.Service
Each component has an event queue (Event Queue) to save the event that it is associated with end.One event package contains
There are one or more conditional branchings, a conditional branching is made up of one or more conditional branching.Condition is by conditional operation
What function (Condition function) and logical operator combined.With a list in Condition objects
(List) it is used for storing these conditional operation functions and logical operator.Action command is actually a kind of any type of function
(Function), it has no substantive difference with conditional operation function, the difference is that its return value of conditional operation function can only be
True or false Boolean, and action command function can return to any value (including void types).
3 sentences are exactly 3 action commands below：
clear(fromengname)；
clear(uodwaive)；
nest_txn(118980)；
