Weblogic 9.2 webservice client getting ClassCastException XmlTokenImpl

Question

Hi,
I have written a webservice using the JAX-WS notation and Weblogic 9.2 MP3 libraries. I generated the server using jwsc and the client using clientgen. The server is working fine. But whenever I used the generated client stubs, I am getting this error:
java.lang.ExceptionInInitializerError
     at weblogic.wsee.ws.init.WsDeploymentChain.newClientChain(WsDeploymentChain.java:24)
     at weblogic.wsee.ws.WsFactory.callClientListeners(WsFactory.java:108)

I spent lots of time debugging this and I found that this exception was generated when weblogic/xbean is trying to parse the listener-class in wsee-config.xml:
<wsee:listener-class>weblogic.wsee.policy.deployment.ClientPolicyDeploymentListener</wsee:listener-class>
For some reason, this got converted to an XmlTokenImpl object and the code was trying to cast it to com.sun.java.xml.ns.j2Ee.FullyQualifiedClassType. I don't know why it wasn't converted to the right class. But I noticed that the wseeConfig.xsd has this:
<import namespace="http://java.sun.com/xml/ns/j2ee" schemaLocation="../../../../j2ee/descriptor/schemas/j2ee14/j2ee_1_4.xsd"/>
Could it be that this "../../../../j2ee/descriptor/schemas/j2ee14/j2ee_1_4.xsd" is causing some issue?
I had checked, double checked and triple checked my classpath and the jars I am using. I am using the weblogic.jar, xbean.jar, weblogic-container-binding.jar all from the Weblogic 9.2 MP3 server installation.
Anyone has any idea on how to solve this? I am very stuck!

Yes. I am using the 9.2 webservices. This is a new webservice I'm creating. The ant build.xml file to generate it is like this:
<jwsc srcdir="${SRCDIR}/src" destdir="${EXPDIR}/webservice"
tempdir="${WRKDIR}/webservice"
verbose="on" debug="on"
enableAsyncService="false"
classpathref="our.custom.classpath" keepGenerated="true">
<jws file="sdo/webservice/impl/SDOWSImpl.java"
contextPath="SDO" name="SDOService">
<WLHttpTransport contextPath="SDO"
serviceUri="SDOService"
portName="SDOService"/>
</jws>
</jwsc>
The our.custom.classpath is as follows:
<path id="our.custom.classpath">
<pathelement location="${EXPTOP}/log4j/1.29/lib/log4j.jar"/>
<pathelement location="${EXPTOP}/weblogic/9.23/lib/apache_xbean.jar"/>
<pathelement location="${EXPTOP}/weblogic/9.23/lib/xbean.jar"/>
<pathelement location="${EXPTOP}/weblogic/9.23/lib/weblogic.jar"/>
<pathelement location="${EXPTOP}/weblogic/9.23/lib/wsse.jar"/>
</path>
I have to include xbean.jar here because if I didn't, I got "java.lang.NoClassDefFoundError: com/bea/xml/XmlException" during the ant build.
How do I make sure I use the 9.2 style xbeans?
thanks!
