WebDynpro integration

Hi,

I would like to get some pointers to integrate an existing WebDynpro application with another application/portlet running in a WebSphere portal server.

Is it possible to do such an integration? If it is feasible, then I would like to know how. Also, I am interested in knowing if I can directly use the .ear file of the WebDynpro App for such an integration? (<i>I guess it is highly container<i> i.e J2EE Engine</i> specific </i>).

Finally a question little bit off the topic. Are there any plug-ins available for SAP (WebDynpro) integration in WebSphere?

Any pointers will be highly appreciated.
