Migration to Weblogic 10.3.5 + Java 1.6: xml errors

Question

Hi all,
I describe my scenario:
I have a web application that works correctly on weblogic 8.1 + jdk 1.4.
Now i'm trying to migrate this web app on RHEL5 + weblogic 10.3.5 + Java SE Runtime Environment (build 1.6.0_25-b06).
Deploying stage gives me no errors (exploded folder), and application starting too.
But when i go into a section of the application that handles xml files, there are several errors like these, and i can't go on:
(package exception): Error calling (method)
at mypackage...
at mypackage...

I tried these actions, but without success:
- run Classloader Analysis Tool and insert <prefer-application-packages> list in weblogic.xml;
- copy these jars into java endorsed folder;
- force different xml parser into jvm parameters;
- tried proposed solutions about this topic in forum
I'm afraid there's a conflict between jar WL and jar application (or a parsing problem), but i'm not sure.
I hope in your help,
thank you.
