Build a Create Page in OAF!

Here I am posting a step by step tutorial to build a simple CREATE page in OAF. It is a

continuation of an earlier tutorial and so you need to go through that first before going

through this.

Here is the link: Build Simple Search Page in OAFStep1: Build a Create Button

Select the view EmpSearchPG, right click and select New > TableActions. One

region (region1) will be created with region style as FlowLayout.

Change the ID of the above newly created region to ButtonLayoutRN.

Right click ButtonLayoutRN and create a new Item.

Set the below details for the Item

o ID :Create

o Item Style : submitButton

o Attribute

Set:/oracle/apps/fnd/framework/toolbox/attributesets/FwkTbxEmployees/Create

Employee

o Action Type: fireAction

o Event: create

Step 2: Set a Controller

Right clickPageLayoutRN and select Set New Controller.

Give the package name as xxhci.oracle.apps.custom.LabExamples.webui.

Give the class name as EmpSearchCO.

Add the following logic to processFormRequest of EmpSearchCO.java after

super.processFormRequest method.if (pageContext.getParameter("event").equalsIgnoreCase("create")) {

System.out.println("EmpSearchCO: processing create/update");pageContext.setForwardURL("OA.jsp?page=/xxhci/oracle/apps/custom/LabExamples/webui/EmployeeCreatePG",null,OAWebBeanConstants.KEEP_MENU_CONTEXT,null, null, true,OAWebBeanConstants.ADD_BREAD_CRUMB_YES,OAWebBeanConstants.IGNORE_MESSAGES);}

You might get red lines under java classes which are not imported. Bring the cursor on

these red-lined text and click Alt+Enter (JDev automatically tells you to import the class

using Alt+Enter when you move cursor over these lines).Step 3: Build the Create Employee Page (EmployeeCreatePG)

Right click on Project >New >Web Tier >OA Components Page.

Set the Page name as EmployeeCreatePG

Set the package name as xxhci.oracle.apps.custom.LabExamples.webui

Select the pageLayout region of EmployeePG and assign the properties as below

ID : PageLayoutRN

AM Definition :

xxhci.oracle.apps.custom.LabExamples.server.XxhciOafTrngEmpTabAM

Window Title : Employee WindowTitle: Employee

Warn About Change: True

Step 4: Add items to Create Employee Page

Create a region under PageLayoutRN and assign ID as PageButtonsRN.

Set the region style as pageButtonBar

Now we need to create two buttons in this region as APPLY and CANCEL.

For Apply Button:

Right click on PageButtonsRN > New > Item.

Set the properties as

ID :ApplyItem Style :submitButton

Attribute Set : /oracle/apps/fnd/attributesets/Buttons/Apply

Additional Text :Click to save the transaction

Action Type: fireAction

Event: Apply

For Cancel Button:

Right click on PageButtonsRN > New > Item.

Set the properties as

ID : Cancel

Item Style : submitButton

Attribute Set :/oracle/apps/fnd/attributesets/Buttons/CancelAdditional Text : Click to cancel the transaction

Action Type: fireAction

Event: Cancel

Fortext items in page: Right click on PageLayoutRN New Region using wizard.

Enter data as shown in below screenshots

Step 4.1: Select AM and VO instance created during search page

Step 4.2: Give Region ID as MainRN and Region Style as defaultSingleColumn

Step 4.3: Select attributes as below (EmpNo, EmpName and Department)

Step 4.4: Change the prompts of items as shown below (messageInputText)

Click on finish for step 5.

Change the Region Style forMainRN to messageComponentLayout. This is done now as

above region wizard, doesnt have support for messageComponentLayout. Click on Yesbutton when the confirm window pops for change of region style.

Step5: Adding Model Layer Code

Add following code to XxhciOafTrngEmpTabAMImpl.java. Add import statements atthe start and rest of the methods with the class definition.import oracle.jbo.Row;import oracle.apps.fnd.framework.OAViewObject;import oracle.jbo.Transaction;import oracle.jbo.domain.Number;import oracle.jbo.RowSetIterator;

// Creates a new employee.

public void createEmployee(){OAViewObject vo = (OAViewObject)getXxhciOafTrngEmpTabEOView1();// Per the coding standards, this is the proper way to

initialize a// VO that is used for both inserts and queries. See View

Objects// in Detail in the Developer's Guide for additional

information.if (!vo.isPreparedForExecution()){vo.executeQuery();}Row row = vo.createRow();vo.insertRow(row);// Required per OA Framework Model Coding Standard M69row.setNewRowState(Row.STATUS_INITIALIZED);

} // end createEmployee()

// Executes a rollback including the database and the middletier.

public void rollbackEmployee(){Transaction txn = getTransaction();// This small optimization ensures that we don't perform a

rollback// if we don't have to.if (txn.isDirty()){txn.rollback();}}

//Commits the transaction.

public void apply(){getTransaction().commit();}


9/12

Add the following import statement and modify the create method in

XxhciOafTrngEmpTabEOImpl as follows:Add this as a part of import statementsimport oracle.apps.fnd.framework.server.OADBTransaction;

Modify the create method as belowpublic void create(AttributeList attributeList) {

super.create(attributeList);OADBTransaction transaction = getOADBTransaction();Number employeeId =

transaction.getSequenceValue("FWK_TBX_EMPLOYEES_S");setEmpNo(employeeId.toString());

}

Step6: Add Controller logic for Create Employee Page

Right click on PageLayoutRN of EmployeeCreatePG > Set New Controller.Give the values as

Package : xxhci.oracle.apps.custom.LabExamples.webui

Class Name : EmployeeCO

Add the below code to the new CO

Import Statements:import java.io.Serializable;import oracle.apps.fnd.common.MessageToken;import oracle.apps.fnd.framework.OAApplicationModule;import oracle.apps.fnd.framework.OAException;import oracle.apps.fnd.framework.OAViewObject;import oracle.apps.fnd.framework.webui.OADialogPage;import oracle.apps.fnd.framework.webui.OAWebBeanConstants;

processRequest (after super.processRequest):if (!pageContext.isBackNavigationFired(false)) {

OAApplicationModule am =pageContext.getApplicationModule(webBean);

am.invokeMethod("createEmployee");

} else {// We got here through some use of the browser "Back"

button, so we// want to display a stale data error and disallow

access to theOADialogPage dialogPage = new

OADialogPage(STATE_LOSS_ERROR);pageContext.redirectToDialogPage(dialogPage);

}

processFormRequest (after super.processFormRequest):OAApplicationModule am =

pageContext.getApplicationModule(webBean);// Pressing the "Apply" button means the transaction should

be validated// and committed.

if (pageContext.getParameter("event").equalsIgnoreCase("Apply")) {OAViewObject vo =

(OAViewObject)am.findViewObject("XxhciOafTrngEmpTabEOView1");

String employeeName =(String)vo.getCurrentRow().getAttribute("EmpName"

);String employeeNum =


10/12

(String)vo.getCurrentRow().getAttribute("EmpNo");am.invokeMethod("apply");MessageToken[] tokens ={ new MessageToken("EMP_NAME", employeeName),new MessageToken("EMP_NUMBER", employeeNum) };

OAException confirmMessage =new OAException("AK",

"FWK_TBX_T_EMP_CREATE_CONFIRM", tokens,OAException.CONFIRMATION, null);

pageContext.putDialogMessage(confirmMessage);pageContext.forwardImmediately("OA.jsp?

page=/xxhci/oracle/apps/custom/labExamples/webui/EmpSearchPG",null,OAWebBeanConstants

.KEEP_MENU_CONTEXT,null, null, true,OAWebBeanConstants

.ADD_BREAD_CRUMB_NO);}

// If Cancel button is pressed, rollback the transaction

else if(pageContext.getParameter("event").equalsIgnoreCase("Cancel")) {

am.invokeMethod("rollbackEmployee");pageContext.forwardImmediately("OA.jsp?

page=/xxhci/oracle/apps/custom/labExamples/webui/EmpSearchPG",null,OAWebBeanConstants

.KEEP_MENU_CONTEXT,null, null, false,OAWebBeanConstants

.ADD_BREAD_CRUMB_NO);

}

Step 7: Save all and Run the EmpSearchPG to test the page
