What is the knowledge in OAF development?
This article is to share with you about the knowledge of OAF development, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.
Small knowledge points summarized during OAF development:
1: conversion between variable types:
(1): int = > other types
Int xxxx
Number yyyy = (Number) xxxx
Number yyyy=new Number (xxxx)
String yyyy = String.valueOf (xxxx)
String yyyy = Integer.toString (xxxx)
String yyyy = "" + xxxx
(2): number = > other types
Number xxxx
Int yyyy = xxxx.intValue ()
Int yyyy = (int) xxxx
String yyyy = "" + xxxx
String yyyy = String.valueOf (xxxx)
(3): date = > other types
Date xxxx
String yyyy= String.valueOf (xxxx)
String yyyy= xxxx.toString ()
(4): String = > other types
String xxxx
Int yyyy = Integer.parseInt (xxxx)
Int yyyy = Integer.valueOf (xxxx)
Try {
Number yyyy = new Number (xxxx)
}
Catch (Exception e) {
}
Number yyyy = (Number) xxxx
Date yyyy = Date.valueOf (xxxx)
Date yyyy = (Date) xxxx
Some basic implementation methods between 2:OAF:
(1): generally do not write specific logic code in CO, put all methods into AM, and then call functions or procedures in AM in CO. The specific methods are:
OAApplicationModule am = pageContext.getApplicationModule (webBean)
Calling procedure: String useId = "" + useid
Serializable [] parameters = {useId}
Am.invokeMethod ("init", parameters)
(am.invokeMethod ("init");
Call function: String supplierid = Integer.toString (n)
Serializable [] param = {supplierid}
Serializable SupplierName = am.invokeMethod ("GetSupplierName", param)
Note: SupplierName can be used directly, depending on the type returned by the function.
3: the method of obtaining and assigning variables or items on the page:
(1): the value of the variable passed in on the link:
(OA.jsp?page=/oracle/apps/xxpos/xxpos5961/back/webui/CreatePG&BackNumber= {@ BackNumber} & HeaderId= {@ HeaderId} & HeaderStatus= {@ HeaderStatus} & retainAM=Y&addBreadCrumb=Y&UpdateFlg=Y)
String backnumber = pageContext.getParameter ("BackNumber")
(2): get the item on the page:
OAMessageLovInputBean asnBean1 = (OAMessageLovInputBean) webBean.findChildRecursive ("NumberFromSearch")
String aa= ""
AsnBean1.setValue (pageContext,aa)
4: how to get the VO and the current line:
OAViewObject voDetail = (OAViewObject) am.findViewObject ("BackPVO1")
BackPVORowImpl rowDetail = (BackPVORowImpl) voDetail.getCurrentRow ()
How to get a field in VO:
String N = "" + rowDetail.getUserTypeID ()
Or:
Number headerid =
(Number) voDetail.getCurrentRow () getAttribute ("HeaderId")
5: loop the method of judging the records on the page:
/ / verify whether the paid-in quantity is greater than the replacement quantity
OAViewObject voline = (OAViewObject) am.findViewObject ("DetailLineVO1")
Row rowLine = voline.first ()
Int rec_record = 0
While (rowLine! = null) {
Number backquan = (Number) rowLine.getAttribute ("BackQuantity")
Number actualquan = (Number) rowLine.getAttribute ("ActualQuantity")
String TOsubinv = (String) rowLine.getAttribute ("ToSubinventoryCode")
String TOlocator = "" + (Number) rowLine.getAttribute ("ToLocatorId")
Rec_record = rec_record + 1
String record_num = "" + rec_record
String ACTUALQUAN = "" + actualquan
If (! (TOsubinv! = null & & TOsubinv.length ()! = 0)) {
System.out.println ("enter this 1111")
MessageToken [] errTokens = {new MessageToken ("RECORD_NUM", record_num)}
Throw new OAException ("XXPOS", "FWK_TBX_T_BACK_NO_TOLOTSUB", errTokens)
}
If ("null" .equals (TOlocator)) {
System.out.println ("enter into here 2222")
MessageToken [] errTokens = {new MessageToken ("RECORD_NUM", record_num)}
Throw new OAException ("XXPOS", "FWK_TBX_T_BACK_NO_TOLOCATOR", errTokens)
}
If ("null" .equals (ACTUALQUAN)) {
System.out.println ("enter into here 3333")
MessageToken [] errTokens = {new MessageToken ("RECORD_NUM", record_num)}; throw new OAException ("XXPOS", "FWK_TBX_NO_ACTU_QUAN", errTokens)
}
Else {
If (backquan.compareTo (actualquan))
