JAX-WS Dispatch client was working fine until wlfullclient.jar was added
===

I have a standalone batch program which runs on jdk1.6.0_31. This standalone program has JAX-WS client and EJB client. JAX-WS client was working fine without adding any jars until I added wlfullclient.jar for EJB client. Now with wlfullclient.jar in classpath I am getting the below exception. Please let me know how to resolve this. Appreciate your help.
