How to Create OAF Insert/Update/Delete Page in R12.2.6
How to Create OAF Insert/Update/Delete Page
In this exercise we will create a OAF Page with Search , Insert ,Update and Delete Operations on the same page.
For this we will create a custom table under APPS Schema to perform this task.
CREATE TABLE apps.xxdcb_employee
(
employee_id NUMBER,
first_name VARCHAR2 (240),
last_name VARCHAR2 (240),
full_name VARCHAR2 (2000),
start_date DATE,
salary NUMBER,
position VARCHAR2 (240),
manager_name VARCHAR2 (240),
created_by NUMBER,
creation_Date DATE,
last_update_login NUMBER,
last_update_date DATE,
last_updated_by NUMBER
);
Step 1: Create a New Work space and Project
Step 2: Create a New Entity Object
Right click on Current Work space -> Business Tier -> Entity Object
Select the Table created earlier .Make sure Package is under server.schema as shown below
Since Primary Key does not Exists in table ,Wizard will Generate a ROWID By default.
Step 3: Create a New View Object (VO)
Generate VO from the EO Generated above.make sure you generate VOImpl and VORowImpl
Once finished Step 2 , 3 final One will look line the below in the Application Navigator
Step 4: Attach View Object (VO) to Application Module (AM)
Set below Property to AM since this AM we will be using for Insert,Update ,Delete operations also.
Right click on SearchAppAM -> Edit SearchAppAM -> Custom Properties
Name RETENTION_LEVEL
Value MANAGE_STATE
Step 5: Create a New OA Page
Set the below properties for the page.

Class Name InsertEmployeeCO
Step 17: Add the following code under SearchAppAMImpl.java file
public void apply(){
getOADBTransaction().commit();
}
public void rollback(){
getOADBTransaction().rollback();
}
public void createRecord()
{
OAViewObject vo = getXxdcbEmployeeEVO();
if (!vo.isPreparedForExecution())
{
vo.executeQuery();
}
Row row = vo.createRow();
vo.insertRow(row);
row.setNewRowState(Row.STATUS_INITIALIZED);
}
Step 18: Add the below code in EmployeeSearchCO.java under processFormRequest method.
if (pageContext.getParameter("Create") != null)
{
pageContext.forwardImmediately(
"OA.jsp?page=/xxdcb/oracle/apps/fnd/webui/InsertPG",
null, OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
true, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
}
Step 18: Add the below code in InsertEmployeeCO.java
package xxdcb.oracle.apps.fnd.webui;
import oracle.apps.fnd.common.VersionInfo;
import oracle.apps.fnd.framework.OAApplicationModule;
import oracle.apps.fnd.framework.OAException;

*/
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
{
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("createRecord", null);
}
/**
* Procedure to handle form submissions for form elements in
* a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
*/
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
{
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
// Pressing the "Apply" button means the transaction should be
// validated and committed.
if (pageContext.getParameter("Create") != null)
{
OAException message = new OAException("Record has been Inserted!", OAException.INFORMATION);
pageContext.putDialogMessage(message);
am.invokeMethod("apply");
pageContext.forwardImmediately(
"OA.jsp?page=/xxdcb/oracle/apps/fnd/webui/EmpSearchPG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
true, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
}
else if (pageContext.getParameter("Cancel") != null)
{
am.invokeMethod("rollback");
pageContext.forwardImmediately("OA.jsp?page=/xxdcb/oracle/apps/fnd/webui/EmpSearchPG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
false, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO);

|
Update Page
|
Step 22: Add the Beans to the MainRN similar way how we created Insert page as shown below
Step 23: Set New Controller to the update Page .
Step 24: Add the following code under SearchAppAMImpl.java file
public void initUpdateRow(String empId)
{
OAViewObject vo = getXxdcbEmployeeEVO();
vo.setWhereClause("employee_id = :1");
vo.setWhereClauseParams(null); // Always reset
vo.setWhereClauseParam(0, Integer.parseInt(empId));
vo.executeQuery();
}
Step 25: Add the following code under UpdateCO.java file
package xxdcb.oracle.apps.fnd.webui;
import java.io.Serializable;
import oracle.apps.fnd.common.VersionInfo;
import oracle.apps.fnd.framework.OAApplicationModule;
import oracle.apps.fnd.framework.webui.OAControllerImpl;
import oracle.apps.fnd.framework.webui.OAPageContext;
import oracle.apps.fnd.framework.webui.OAWebBeanConstants;
import oracle.apps.fnd.framework.webui.beans.OAWebBean;
/**
* Controller for ...
*/
public class UpdateCO extends OAControllerImpl
{
public static final String RCS_ID="$Header$";
public static final boolean RCS_ID_RECORDED =
VersionInfo.recordClassVersion(RCS_ID, "%packagename%");
/**
* Layout and page setup logic for a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
*/
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
{
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
String employeeId = pageContext.getParameter("empid");
Serializable[] params = { employeeId};
am.invokeMethod("initUpdateRow", params);
}
/**
* Procedure to handle form submissions for form elements in
* a region.
* @param pageContext the current OA page context
* @param webBean the web bean corresponding to the region
*/
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
{
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (pageContext.getParameter("Update") != null)
{
am.invokeMethod("apply");
pageContext.forwardImmediately("OA.jsp?page=/xxdcb/oracle/apps/fnd/webui/EmpSearchPG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
false, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
}
else if (pageContext.getParameter("Cancel") != null)
{
am.invokeMethod("rollback");
pageContext.forwardImmediately("OA.jsp?page=/xxdcb/oracle/apps/fnd/webui/EmpSearchPG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
null,
false, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
}
}
}
Step 26: Run the EmpSearchPG and check is the update is working as expected.
Step 27: Add the below code in the SearchAppAMImpl.java for the Delete operation
public void deleteRecord(String employeeId)
{
OAViewObject vo = getXxdcbEmployeeEVO();
XxdcbEmployeeEVORowImpl row = null;
int fetchedRowCount = vo.getFetchedRowCount();
RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");
if (fetchedRowCount > 0)
{ deleteIter.setRangeStart(0);
deleteIter.setRangeSize(fetchedRowCount);
System.out.println("employeeId"+employeeId);
for (int i = 0; i < fetchedRowCount; i++)
{
row = (XxdcbEmployeeEVORowImpl)deleteIter.getRowAtRangeIndex(i);
if(row.getEmployeeId().intValue()==Integer.parseInt(employeeId)){
row.remove();
getTransaction().commit();
break;
}
}
}
deleteIter.closeRowSetIterator();
}
Step 28: Add the below code in the EmployeeSearchCO in ProcessformRequest Method
if ("delete".equals(pageContext.getParameter(EVENT_PARAM)))
{
String rowRef = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
OARow row = (OARow)am.findRowByRef(rowRef);
employeeId = row.getAttribute("EmployeeId");
OAException message = new OAException("Are you sure you want to delete this row?",OAException.WARNING);
OADialogPage dialogPage = new OADialogPage(OAException.WARNING, message, null, "", "");
String yes = pageContext.getMessage("AK", "FWK_TBX_T_YES", null);
String no = pageContext.getMessage("AK", "FWK_TBX_T_NO", null);
dialogPage.setOkButtonItemName("DeleteYesButton");
dialogPage.setOkButtonToPost(true);
dialogPage.setNoButtonToPost(true);
dialogPage.setPostToCallingPage(true);
dialogPage.setOkButtonLabel(yes);
dialogPage.setNoButtonLabel(no);
pageContext.redirectToDialogPage(dialogPage);
}
else if (pageContext.getParameter("DeleteYesButton") != null)
{
Serializable[] parameters = { employeeId.toString() };
am.invokeMethod("deleteRecord", parameters);
OAException confirmation = new OAException("Record deleted Successfully", OAException.CONFIRMATION);
pageContext.putDialogMessage(confirmation);
}
Step 29: Save all the changes and run the EmpSearchPG to test delete functionality.
Congratulations, you have done it. we have build a Simple Search,Insert,Update, Delete Page a Fully functional Page.!
