I used 4.2.1.GA

This is the classpath from my build.xml:

  <path id="j2ee.classpath">
    <fileset dir="${j2ee.dir}">
      <include name="lib/**.jar"/>
      <include name="server/${j2ee.jboss.config}/lib/**.jar"/>
      <include 
name="server/${j2ee.jboss.config}/deploy/ejb3.deployer/**.jar"/>
    </fileset>
  </path>
