Error during deployment of ADF 11g application server:

In Application Resources Pallette -> weblogic-application.xml add below lines

ADF SelectOneChoice without base datasource

PageDefinition:
Create Iterator in your executables section.
and create a list binding in your bindings section to this iterator.
Sample page definition code:

Page:
Drag and drop the selectonechoice component and bind it to above created binding.

Note that selectonechoice will return index, use iterator bind to get the value at selected index below is backing bean code
public void choiceListListener(ValueChangeEvent valueChangeEvent) {
DCIteratorBinding iter=((DCBindingContainer)getBindings()).findIteratorBinding("Departments1View1Iterator");
Row r=iter.getRowAtRangeIndex((Integer)valueChangeEvent.getNewValue());
System.out.println("Attr names"+r.getAttribute("DepartmentId"));
System.out.println("Attr names"+r.getAttribute("DepartmentName"));
System.out.println("atr1");
//set value of your variable equal to "value"
}

Iterator throws java.lang.NullPointerException

1) Go to page defination of JSF page
2) Select the Iterator you are using
3) Right click -> go to properties
4) In porperties change the RangeSize property to -1

Deploy ADF application on weblogic server (10.3)

(prerequisite) Create JNDI on weblogic server
In JDeveloper in
Model-> Rt clk your ApplicationModule file-> Configuration
- Edit both the setting (AppLocal & AppShared)
- Select Connection type to JDBC datasource (default is JDBC URL)
- Give proper DS name e.g java:comp/env/jdbc/MyDS (Note: Same DS name should be thr in weblogic server)
- Follow this for AppShared
- Now, Right clk ur application -> Deploy to EAR file
you can deploy EAR file on WEBLOGIC

Change the jbo.lockingmode property to optimistic

Select application module-> rt clik -> Configurations -> Edit -> (Properties tab)
Property: jbo.locking.mode replace pessimistic with optimistic

1) Programmatically accessing values from managed bean & Programmatically executing view with parameters

UserDetailsPersist obj1 = (UserDetailsPersist)JSFUtils.getFromSession("UserDetailsPersistent");

ApplicationModule am = ADFUtils.getApplicationModuleForDataControl("RotaAppDataControl");
ViewObject vo = am.findViewObject("StartDay");
vo.setNamedWhereClauseParam("locId",obj1.getLocationId());
vo.executeQuery();

while (vo.hasNext())
{
StartDayRowImpl currRecd = (StartDayRowImpl) vo.next();
System.out.println("Now accessing department " + currRecd.getWeekDesc());
startDayNo = currRecd.getWeekDesc().toString();
}

System.out.println("Start day no"+startDayNo);
