Recently OpenPortal Portlet Container was fully integrated in Liferay Portal. The OpenPortal Portlet Container is a fully compliant implementation of the Portlet 2.0 (JSR286) specification. And it also implements many of the optional features like expiration and validation caching, support for alias in eventing and public render parameters, support for wild card in eventing.
The integration was done based on the steps documented in this article.
The WSRP 2.0 implementation provided by the WSRP Project works seamlessly with this Portlet Container. Thus the embedding of the Portlet Container in Liferay Portal ensures that the WSRP 2.0 implementation can also be integrated.
