Jython WL 9.2 WebSvc Client?

[Neil Pointer]

I'm trying to use The Grinder to test my WL 9.2 websvc and their example JAX-RPC script seems to be missing something.

A j2se tester using websvc cli, weblogic and webservicesclient jars works just fine, so same jars are added to the jython execution.

But the jython script errors like this:

java.lang.ClassCastException: weblogic.xml.stax.XMLStreamInputFactory
at javax.xml.stream.XMLInputFactory.newInstance(XMLInputFactory.java:136)

The weblogic XMLStreamInputFactory extends XMLInputFactory, so that shouldn't be it.

I have also added these settings to make sure all's well, but all's unwell:

System.setProperty( "javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl")
System.setProperty("javax.xml.stream.XMLOutputFactory", "weblogic.xml.stax.XMLStreamOutputFactory")   
System.setProperty("javax.xml.stream.XMLEventFactory", "weblogic.xml.stax.EventFactory")
System.setProperty("javax.xml.stream.XMLInputFactory", "weblogic.xml.stax.XMLStreamInputFactory")

Any hints would be appreciated. Thanks.
