Using Oracle AS Web Services stub in portlet?

Question

I have built a portlet using the jdeveloper plugin wizard, and added a web service stub using the jdeveloper wizard for that. I have added no other code to the portlet than the stub. When running the portlet the classloader throws an class format exception. When using the same stub in a standalone application it runs fine. The libraries mentioned in jdevelopers under the system library "Oracle SOAP" has all been added to the webapplication web-inf/lib. How do I fix it?

We have solved the problem. It turned out that the auto generated stub contained code not compatible with the OC4J class loader (but compatible with normakl JVM classload). By modifying the stub a little we got it working. Here is the an extract from one method in the stub. The two line that work comes first and the two next lines contains the auto generated code
public Integer dispatchFile(byte[] fileContent, Integer programID) throws Exception {
params.addElement(new Parameter("fileContent", fileContent.getClass(), fileContent, null));
params.addElement(new Parameter("programID", programID.getClass(), programID, null));
// params.addElement(new Parameter("fileContent", byte[].class, fileContent, null));
// params.addElement(new Parameter("programID", Integer.class, programID, null));
The two original lines compiles into some static class members and a static method that fails to load.
The new code does not produce any static content.
We consider this behaviour to be an OC4J error.
