I hope I'm not being too forward, but could you perhaps send me a WAR file that works for you on Tomcat 5.5? (Perhaps a simple app that has a single table in MySql.) My e-mail address is mlh496.register(a)gmail.com If I had a working MySql example on Tomcat 5.5, then I'm sure that I could identify where I am going wrong. Thank you again for your help. I've been stuck in configuration heck for 12 days now, and you've been most helpful. -Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027386#...
