java.lang.ClassCastException

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?

Here is the actual code

Thanks for your help.

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