[jboss-user] [JBoss Seam] - Application-exception handling

[parszab]

Hi Seam-Lovers,
I'm developing a web interface for an old EJB3 application of ours, and wanted to try Seam to do it. So far I love the tool, but now I ran into a trivial thing that I just cannot resolve, and was hoping that you could pont me in the right direction.

So, we had dozens of session-beans in the application that were called from both a remote client  and a small web client (tapestry), too. For the new seam based ui I created pojo action classes to acces those session-beans. With these action classes a new layer had been introduced, but that works for us, because we have to provide the same bl for the remote clients.

However: those session-beans throw custom, application exceptions that I don't know how to handle within seam. I know there is the xml configured exception handling, but we need a more complex behavior, like specifing that the same page should be re-rendered, and a message should be shown on that etc....

Actually what we need, is exactly how hibernate-validator exceptions are handled. My problem is, that I don't know how to implement the whole thing, from filters to renderers. I guess I could get hints from the mentioned validator exc. handling, but I cannot find how that is done (I tried, really!).

So if just someone could tell me where I should look for that in Seam I'd be really grateful!

Thanks a lot!
