This tip is intended to help you deploy the ActuateJavaComponent.war file on JBoss 5.0. This was tested with JBoss 5.0.1 GA and ActuateJavaComponent.war version 10 SP1 Fix3.
The AcuateJavaComponent.war contains xercesImpl.jar in the WEB-INF/lib directory and this conflicts with xercesImpl.jar file in the lib/endorsed directory of JBoss. JBoss contains a newer version of this this file and it is safe to remove the xercesImpl.jar file from the WEB-INF/lib directory of the WAR file.
