I need a complete Book for JBoss Portal development. Does it exist? If not, how can I learn developing for JBoss Portal?
I founded only books about JBoss server development, but what I need is to learn how to configure my portlets for JBoss Portal, how to use configure Hibernate for using Portal with MySQL or Oracle and how to develope a portlet from the beginning

I tried to watch the examples, but it's hard to learn from samples without docs...
