Using CSSDK with WebSphere Portal 5.1

Achim

Hi everybody,

I've got a frustrating little problem here. Maybe some has an idea how to resolve this.

The Situation:
I try to use the Interwoven CSSDK to manipulate DCRs. This works fine as long as I do it locally or even when done by a servlet on a WebSpeher 5.0 Application server. But as soon as I try to implement it as portlet on a WebSphere Portal 5.1 Server I get the following exception:

java.lang.LinkageError: Class javax/xml/transform/Source violates loader constraints: definition mismatch between parent and child loaders

It seems that early versions of Apache's Axis, as the one the CSSDK uses, define their own versions of javax/xml/transform/Source and some subclasses, as does the WebSphere portal xml library. Some information I found on the web indicates, that later versions of axis resolve that issue, but the CSSDK isn't happy with them.
Also tried to repack the Axis libraries and just leave out the classes in conflict, but this doesn't work neither. Now I ran out of ideas other then writing my own class loader, which I really don't fancy very much.

So if anyone has a solution or idea I can ensure here/him of my eternal gratitude.

Sincerely,
Georg Göttlich
