I'm running JBoss 6.1 Final on an XP machine w/SP3. I'm using MyEcplise instead of Eclipse. In the last couple of weeks I'm starting to get the above error when deploying the bean. There are two other developers on our team w/the same setup that do not get any errors deploying the same source code/bean. I have copied another developer's JBOSS 6.1 code to my computer and the issue goes away. That developer is using the same code. FYI: The javasource code has no errors. I'm trying to run jboss from the command prompt but I get a java_home is not set even though it is and it start's up in MyEclipse without a problem. Below is the complete exception dump. I've found nothing on goggle regarding this issue. By the way, the below exception is constantly repeated as though it's trying to redeploy the bean.
