Hello,
As already announced, Portal for Java 0.8.0 has been completely redesigned and became more simple and concise than before. I'm sorry for the compatibility issue but it was inevitable. For the new features and migration, see an announce.
And one more thing, as you will see, Portal for Java 0.8.0 is built on top of wes (Web Event Source). The wes is a project designed to enable library or framework like Portal for Java to run on as many platform and framework as possible. Take a look at wes If you are interested.
Thanks,
