Thanks for the advice but I already took a look at is as also to cocoon.
Thing is that I'm not really looking for a tool for a "only content website".
The current application is a complex application with a lot of business logic and depending on the user input the application is intented to give advice to the customer and this advice sould be some pieces glued togetter, but I want the get rid off all the magement of these pieces (the content off them).
Info appl. run under Spring - Sping webflow - hibernate and a Weblogic 9.x.
