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))
