You can avoid the classcast Exception by adding the following variables to your System Properties: -Djavax.xml.stream.XMLInputFactory=com.bea.xml.stream.MXParserFactory -Djavax.xml.stream.XMLEventFactory=com.bea.xml.stream.EventFactory -Djavax.xml.stream.XMLOutputFactory=com.bea.xml.stream.XMLOutputFactoryBase FactoryFinder.find() in stax-api.jar looks for the above System properties. (In the above case, I was using stax.jar ) Thanks Ezhil View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221166#...
