I am facing an issue when trying to pass Oracle collection object(User Defined Types) from Java to PL SQL. The issue happens inside J2EE application which is running inside Websphere Application Server 6.x. My database is Oracle 10g and i am using ojdbc1.4.jar as thin driver.

The issue is that when i pass the Oracle Object from java side, the attribute values of the collection objects at the Oracle PL SQL side is coming as empty. I have tried the same java code in a standalone application and it works fine. The issue happens only when the application is running inside WAS.
Anybody has any idea how to pass Oracle User Defined Types from WAS 6.x server to Oracle PL SQL?
