Also, you never answered my question: anonymous wrote : are attempting to replace the hsqldb with MySQL? If the answer to that question is "yes," then are you past the initial problem you posted and on to another problem with deploying your EJB? Which did you do first - start jbossas, or deploy your EJB? CR1 is a little buggy when it comes to startup deployment, try starting jbossas first, wait until you see the "Started in" message, and then deploy your EJB. (Or better yet, move up to CR2, many of the deployment-on-startup issues have been fixed in CR2.) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179199#...
