I already have soap based web service running with axis2 1.3. These day, we have a plan to develop RESTful web service using Jersey 1.6.

I made web application( war file ) with axis2 1.3 and Jersey 1.6 and try to deploy it on jboss5.1.0.

After start jboss I saw below error message.

There are two versions of the javax.xml.namespace.QName class being provided in your environment:

  1. The first is in Java SE 6.
  2. The second appears to be provided by JBoss
