Please help resolve java.lang.LinkageError

Hello and thank you in advance for your help.

I am deploying an EAR that works on another application server. However I can't get it working on JBoss 4.0.5 due to the following issue:

java.lang.LinkageError: loader constraints violated when linking org/xml/sax/ErrorHandler class

I already tried to remove xalan.xml from EAR and placing them in {Default_Server_Home}/lib directory.

I also tried to remove conflicting version of xerces.xml from the ear.

If anyone knows how to resolve this issue I would be grateful to find out how to do it.

Thank you.

From jdk/docs/api/java/lang/LinkageError.html
This Error descripts:

Subclasses of LinkageError indicate that a class has some dependency on another class; however, the latter class has incompatibly changed after the compilation of the former class

So check your dependency jar version, and should resolve it youself.
