Producing WSRP 1.0/2.0 from a standalone webapp - state of the art

I intend to produce WSRP interfaces from a standalone Java web application so that one can embed its front-end in portals (Liferay, IBM websphere portal), aside standalone front-end and back-ends.

What is the recommended开发者_运维问答 way to achieve this ? I cannot find out a WSRP producer Java library that seems to do the job. The common practice of WSRP seems to link portals between them, as they natively support WSRP providers, consumers, and portlets specification.

Thanks for your help,

You should be able to use the OpenPortal Portlet Container to do this.
