[JBoss Seam] - How to catch exception when deleting?
by bfo81
I have a Stateful Session Bean with a method delete(). Guess what is does? It deletes an entity ;).
| @Stateful
| @Scope(Scopetype.SESSION)
| @name("foo")
| ...
|
| @In(create=true)
| private EntityManager em;
|
| public String delete() {
|
| em.remove(anEntity);
|
| return "finished";
|
| }
|
Ok, now it could be that the user wants to delete an entity that is referenced by other entities. So an SqlException is thrown telling that a database constraint is violated. I wanted to catch that exception and tell the user that deletion wasn't successful. I tried it like this:
| public String delete() {
|
| try {
| em.remove(anEntitiy);
| } catch (Exception ex) {
| ...addMessage("Deletion failed!");
| }
| return "finished";
| }
|
Unfortunately that doesn't work, the exception isn't caught and Facelets displays an ugly error message.
Well... why? *g*
Here's the log. It's long but please don't be shocked ;).
