Classcastexception using xalan2.4.1 and xercesImpl-2.2.1.jar
Dear all,
I am using Jboss 3.2.3 to deploy my application framework.ear and use my own distribution of Xerces(2.2.1) and Xalan (2.4.1).
Since i want to force Jboss to first load jars of the EAR I have put the jboss-app.xml in META-INF as follows:
<jboss-app>
<loader-repository>frameworkdomain:LoaderRepository=framework.ear</loader-repository>
</jboss-app>
When now starting JBOSS, the following classcastexception is thrown during deployment of my entitybeans.
[EntityContainer] Starting failed

Apparently there is still a conflict in classloading with other JAXP libs shipped with JBOSS:
JBOSS_HOME/lib/xercesImpl.jar and JBOSS_HOME/server/default/lib/xalan.jar
Apparently the application is not shielded of from the jboss system environement.
Is there anyone who experienced a similar issues ?
Thanks in advance for your feedback!!
Best regards
Pascal
