java.lang.NoClassDefFoundError: org/jaxen/JaxenException

Hello,
I have deployed my EAR in jboss 4.0.4 and when I try to use a component that use dom4j I have the following error :
java.lang.NoClassDefFoundError: org/jaxen/JaxenException

The jaxen.jar library is in my EAR and in the classpath of the session bean which call the windward Component (in the manifest).
Any suggestions for the cause of the problem ?
Please help

Try packaging dom4j.jar in your ear file.

[taha1967]

I did but no way, jboss use the it's dom4j (jboss_home/lib)

[jiwils]

Try scoping your EAR. Have a look at http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration which describes how to do this.

a quick (and of course dirty) solution is to use the jboss unified class loader. In your
\deploy\jbossweb-tomcat55.sar\META-INF\jboss-service.xml,
change the to true.
Let me know if it works. (Please do not do this if you have multiple applications)

[anishx]

i mean change the UseJBossWebLoader to true.
damn.. xml tags dont show up in the forum :p
