It seems the jars in libs/endorsed are needed with jdk6:

<patternset id="jbossws.lib.endorsed.patternset">
<include name="**/jboss-jaxrpc.jar"/>
<include name="**/jboss-jaxws.jar"/>
<include name="**/jboss-jaxws-ext.jar"/>
<include name="**/jboss-saaj.jar"/>
<include name="**/jaxb-api.jar"/>
</patternset>

The hudson script now copies jboss-jaxrpc.jar, jboss-jaxws.jar, jboss-saaj.jar
