java.lang.ClassCastException

[wrwelden]

Hello,

I am new to java> I have built a web page to query an oracle table and return rows of data. I have added a button to execute a delete method. When executing the delete method, I get the following error:

What is the problem and how do I correct it?

## Detail 0 ##
java.lang.ClassCastException
at oracle.apps.cust.xxdpOrgDesc.server.xxdpOrgDescAMI mpl.DeleteOrgDescRow(xxdpOrgDescAMImpl.java:59)

//*** ---- *** This is the row referenced in the error message *** ---- ****

Xxdp00OrgDescriptionsVORowImpl rowi = (Xxdp00OrgDescriptionsVORowImpl)row[i];

//*** ---- *** ----------------------------------------------- *** ---- ****
Error Explanation:
Thrown to indicate that the code has attempted to cast
an object to a subclass of which it is not an instance.

Sounds like your trying to make one object be another object. For example you can not in java make a class called Car and try to cast it to a fruit. It won't let you.

It seems row[i] doesn't contain an instance of Xxdp00OrgDescriptionsVORowImpl. Can you show the actual code leading to this line?

[wrwelden]

Here is the actual code

Code:

package oracle.apps.cust.xxdpOrgDesc.server;
import oracle.apps.fnd.framework.server.OAApplicationModuleImpl;
import oracle.apps.cust.xxdpOrgDesc.webui.Xxdp00OrgDescriptionsVOImpl;
//import oracle.apps.fnd.framework.server.OAUtility.*;
import oracle.jbo.Row;
//import oracle.apps.fnd.framework.server.*;
//import oracle.apps.fnd.framework.*;
 
//  ---------------------------------------------------------------
//  ---    File generated by Oracle Business Components for Java.
//  ---------------------------------------------------------------

public class xxdpOrgDescAMImpl extends OAApplicationModuleImpl 
{
  /**
   * 
   * This is the default constructor (do not remove)
   */
  public xxdpOrgDescAMImpl()
  {
  }

  /**
   * 
   * Container's getter for Xxdp00OrgDescriptionsVO
   */                                
      public Xxdp00OrgDescriptionsVOImpl getXxdp00OrgDescriptionsVO1()
  //     public Xxdp00OrgDescriptionsVOImpl getXxdp00OrgDescriptionsVO() /* orig */
  {
  // return (Xxdp00OrgDescriptionsVOImpl)findViewObject("Xxdp00OrgDescriptionsVO");       /* orig */
     return (Xxdp00OrgDescriptionsVOImpl)findViewObject("Xxdp00OrgDescriptionsVO1");
  }

  /**
   * 
   * Sample main for debugging Business Components code using the tester.
   */
  public static void main(String[] args)
  {
    launchTester("oracle.apps.cust.xxdpOrgDesc.server", "xxdpOrgDescAMLocal");
  }
/*
 *  Beginning of Delete Method - DeleteOrgDescRow
 */          
public void DeleteOrgDescRow( String pAction, String pRowID )
{
System.out.println("xxDebug inside deleteOrgDescRow()") ;
//  Xxdp00OrgDescriptionsVOImpl orgvo = getXxdp00OrgDescriptionsVO() ;   /* orig */
    Xxdp00OrgDescriptionsVOImpl orgvo = getXxdp00OrgDescriptionsVO1() ;  /* test */
System.out.println("pAction IS: "+pAction) ;
System.out.println("ROW_ID IS: "+pRowID) ;
Row row[]=orgvo.getAllRowsInRange();


for ( int i=0;i<row.length;i++)
{
System.out.println("i IS: "+i) ;
System.out.println("i end IS: "+row.length) ;
//Xxdp00OrgDescriptionsVORowImpl rowi = (Xxdp00OrgDescriptionsVORowImpl)row[i];
Xxdp00OrgDescriptionsVORowImpl rowi = (Xxdp00OrgDescriptionsVORowImpl)row[i];
System.out.println("xxDebug Checking to delete RowID => " + rowi.getRowID());
if (rowi.getRowID().toString().equals(pRowID))
{
	rowi.remove();
	getOADBTransaction().commit();
	return ;
}
}
/*
 * End of Delete Method
 */
 
}
}

Thanks for your help.

What is the signature for this method: orgvo.getAllRowsInRange(); ?
