This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I used WSRP when it was built right into WebSphere 5 Portal, but it really seemed to disapper with version 6. However, it has been very tightly aligned with JSR-286, so hopefully we'll see better support for it in the next generation of portal servers.
