      Hi,
      I'm trying to use JBoss 4.0.5.GA on an AIX server with IBM JRE 1.4.2
      I get this exceptions at startup:

      No problems with:
      - JBoss 3.2.1 with same AIX server and same JRE
      - JBoss 4.0.5 GA on Windows XP with JDK 1.4.2

      I noticed that the IBM JRE 1.4 has a file <JAVA INSTALLATION DIR>/jre/lib/xml.jar and I think that it could be the reason of the ClassCastException, with a clash between that jar file and JBOSS/lib/endorsed/xercesImpl.jar

      Am I correct? How can I solve this problem?

      Thanks in advance,
      Andrea
