I have a application packaged as ear and har files. The can be successfully deployed on JBoss 4.0.2 on other machines (at least one linux and one windows), but when I attempt to deploy on my machine (windows XP, JBoss 4.0.2) I get some errors in the log (at end of post). I have changed the jdbc connection to point to the correct database locally (MySql), and all database references appear to point to the connection defined in mysql-ds.xml. I do not have a lot of experience with JBoss, but I am working with someone who does, and he is just as stumped as I am.

I've already removed and reinstalled JBoss (I've also tried 4.0.3, but that didn't work either) and the jdbc driver jar is good (at least it works in other non-JBoss applications.

I know that it's a bit vague, but I'm hoping that somebody can give me some pointers to help track down this problem (at least if it failed on all my machines, it would make a bit more sense).

Thanks.
