[JBoss Tools (users)] - Re: Hibernate reverse engineering errors
by bdlink
OK, I edited the reveng.xml file by hand, eliminating all of the empty string attribures, and that eliminates the exception (cheers!)
I looked at my DB to see why extra associations were showing up and found duplicate foreign key constraints that mysql added at some time, and when I removed these, I get the associations I would expect.
So things are much improved! There are some remaining issues I am looking at including :
1. Even though I annotate a foreign key with one-to-one, the property is marked with @ManyToOne and the inverse side uses a Set (when it is not excluded).
2. I have one case where there are two associations between Student and Review (both one Student to many Reviews). In the ReviewHome class it injects two studentHome components (duplicate names), where one of them should be a different @Role. (I think this is in JIRA from long ago, but I will check later)
The one-to-one issue is obviously more important.
Updated reveng.xml:

[JBoss Cache: Core Edition] - Re: on child insert parent, child collection updated in DB b
by dukehoops
Here's my first take on a unit test that builds/runs as part of org.hibernate.test.cache.jbc2 maven project.
The problem is that this test (since it tests concurrency) requires JTATransactionManager impl that can handle multiple concurrent Transactions. And SimpleJtaTransactionManagerImpl is only suitable for single thread tests. So testManyUsers() fails for all the wrong reasons.
Does anyone know which TX Manager impl I should be using in this test environment? If one isn't available (then how is concurrency under JTA being tested?) - any hints on the simplest way to plug in a real impl?

[Installation, Configuration & DEPLOYMENT] - IllegalStateException(s) on logout
by kj_newbie
Hi All,
I am using JBoss 5 GA on solaris 10/x86 machine.
Everytime someone logs out from a web app that is deployed in this container, we see the following exception in the shell where JBoss was started:
ERROR [CoyoteAdapter] An exception or error occurred in the container during the request processing

This is when the application is being accessed without any issues.
There is another scenario that occurs sometimes where-in, once a person logs in and out successfully, the next person who logs-in is not able to access any page - all pages display an access denied message. The exception thrown in this case is as follows:
