[JBoss jBPM] - Re: fault never reaches catchall
by meghanai_99
I followed the instructions on the wiki page to build JBPM locally and deploy to JBoss. Only difference in my environment is that I use JBoss.4.0.5.GA.
First I had manually copy jbpm-jpdl.jar to default\lib folder. Now I am getting following exception on server start up
12:14:22,182 ERROR [JobExecutorThread] exception in job executor thread. waiting

Looks like something is misconfigured in one of the hibernate mapping files. Can you please tell me how I can fix this problem?
Thank you,
Meghana

[JBoss Seam] - Security: access control at entity level?
by kingcu
After reading chapter 20 of the Seam book, it seems to me that Seam has built in security support for access control at the method level of session beans. I wonder if the @Restrict annotation can be put on entities to control access to certain entities.
Here is my situation: I have some business entities with various relationships between each other (one-to-one, one-to-many, etc) and through foreign keys or mapping tables, they are organized into a tree structure. I'd like to have the admin role to access all the tree entities, while other roles can only access a certain part of the tree. The accessible part of the tree should be defined dynamically, i.e., an admin user logs into a web UI and selects which part of the tree is accessible for each of the other roles.
Any suggestions/ideas on how this could be implemented with Seam? Thanks.
