I was getting something similar and needed to point my runtime classpath at jboss/client jars.

SO Here was the fix to make sure the jboss/client/*.jar is in classpath first.
This was a snippet of the ant task for running my client.

  |         <fileset dir="/usr/local/jboss/client">
  |             <include name="*.jar"/>
  |         </fileset>
  |     </path>
