      Hi friends,


      When I run the Jboss6.0.0.Final server, the following Exception is occured.


      12:12:25,250 WARN  [ClassLoaderManager] Unexpected error during load of:org.w3c.

      Is this problem with jars Available in my J2EE application and Jboss lib jars? (jars conflict) ?

      Do I need to remove any jars?


      Here I added an attachment of my J2EE application jars.


      Please guide me.


      Thanks in Advance.

          Just change in jboss-6.0.0.Final\server\default\deployers\jbossweb.deployer\META-INF
