Confluence 3.0 java.lang.LinkageError

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install autoexport-plugin-1.0.0.beta1.jar into Confluence 3.0.0_01 -> OK 
2. Export a space

There seems to be some kind of mismatch with the XML-parser classes. I was
able to work around by removing xercesImpl-2.8.1.jar and
xml-apis-1.3.03.jar from META-INF/lib. Not sure if this breaks something else.

Removing the jars did solve the problem for me too. I haven't seen any unwanted 
side
effects of this action so far.

Fixed by adding the appropriate exclusions in the pom (same basic fix)  Thanks.

Donald, could you please explain what you did in the pom ?

I still got this problem when I try to export something :

I try to remove the jars as Igor and Tom say but I still got the problem... may 
be a conflict with another plugin ?

I'm not really confident to change the pom file without make a mistake.
Any help/clue will be greatly appreciated :)

Thank you
