Hi,

I'm using JBoss 3.2.1 with Hibernate 2.0.2. I'm using Hibernate's MBean. I'm getting the following exception when my application redeploys. I believe this to be the key to the problem: "The Enum name must be unique, 'OK' has already been added". I've defined a UserType using my own Enum. If I get rid of the Enum and use a String the application redeploys fine. Is there something I can do to make Hibernate redeploy with Enums?

TIA

FYI,

In http://www.hibernate.org/66.htmlUsing%20Hibernate%20with%20JBoss it suggests you put commons-lang.jar in ${JBOSS_HOME}/server/default/lib. Still learning JBoss but it appears that anything in this directory doesn't get redeployed which caused the problem. I moved commons-lang.jar to my deploy directory and the exception went away.
