Vicky, I looked over our patch - if you could update it in the area where error conditions happens - f.ex. F.ex. if the user has specified an incorrect class name, the driver hasn't been deployed to the lib/ directory, if the method doesn't exist on the class and so on. Lets focus on getting the JDBC RA updated first, then we will look at the MCF /CF cases. Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240150#...
