[jboss-user] [Beginners Corner] - JBoss Rules 4.0.0GA

Wed Aug 29 05:54:15 EDT 2007

Hi,

Im having a few issues getting jbrms to work.  I have tried deploying it to both JBossAS 4.2.1 and JBoss Web 1.0.1 and on both instances get errors in many different places.  I have followed the instructions given but cant seem to get around the issue.

One such problem is when I attempt to Open a business rule.  When trying this I get the following exception:
