Re: java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

IIRC in geronimo 1.1 we ship a copy of xerces in <geronimo_home>/lib/ endorsed. You might need to remove this copy or remove the copy from your app or change the <inverse-classloading/> setting in your app to avoid conflicts.
It would be good to know what you do to fix this.... getting it in the documentation would be great. 

thanks

I'm porting my application from WAS 6 to Geronimo 1.1, my  
application is packaged in an EAR which also contains Xerces, what  
should I do to over come this?,
Tomcat recommends setting up endorsed.dirs property, however I have  
no clue on where to do that in Geronimo.

Thanks everyone for your help
