Web Services for Remote Portlets (WSRP) is supported by uPortal as of uPortal 2.2. The WSRP Proxy channel type replaces the Remote Channel that was introduced in uPortal 2.1. This WSRP Proxy acts as a WSRP consumer that can consume content from any WSRP producer, including another uPortal channel. uPortal 2.2 also implements partially implemented a WSRP as a producer. Note that as of Support for that WSRP producer code has since been withdrawn, the code formally deprecated and finally removed from uPortal in uPortal 2.25. Also, WSRP authentication is not (yet) supported.
uPortal partially supports JSR-168 Portlets in uPortal 2.3 through a Portlet-to-Channel adapter. The Portlets will be managed by Apache's Pluto portlet container. As of uPortal 2.5, we expect uPortal to be fully JSR-168 compliant. Beginning in uPortal 3.0, Portlets will become uPortal's native content module, replacing the Channel. Support for IChannels will continue though a Channel-to-Portlet adapter.
