How to create JAXB bindings in jdeveloper 11g for the portlet event payload

Question

I have three projects in JDeveloper 11.1.1.6:
- PortletProducer - provides some portlets
- PortletUser - makes use of these portlets
- SomeData - provides serializable classes for portlets event payload
I configured SomePortlet in PortletProducer to send events of serializable type SomeDataClass (from SomeData project), but whenever i am trying to send event of this class, i am getting an exception:
oracle.portlet.client.container.PortletRemoteException: oracle.portlet.server.container.OperationFailedException: oracle.portlet.wsrp.v2.OperationFailedException: Internal Server Error: java.lang.IllegalArgumentException: Event [someEvent] value is of type [class somedata.SomeDataClass] which does not have a valid JAXB binding configured; configuration may be done in the WEB-INF/portlet.xml or WEB-INF/wlp-framework-common-config.xml files..;
But i have no idea how to perform such bindings in portlet.xml or wlp-framework-common-config.xml (the latter file is also missing in all three projects, while the former exists only in PortletProducer project).
I have a JAXB xsd file created with schemagen.sh (from a jaxb zip) for SomeDataClass, but what do i do with it in order to create a JAXB binding in JDeveloper?
Thanks.

Are you trying to expose an existing system inside of WCS?
If this is the case, you should investigate "External Applications":

This is an out of the box way of embedding external systems, with seperate login pages etc. I think this will achieve what you are trying to do yourself. It even allows for parameterised URLs
