I use FedoraCore 4 and I have installed Jboss 4.0.3SP1 and MySQL 4.1.11 on it. I try to test it with j2eetutorial with the doc "Getting started with JBoss 4.0" but in chapter 8, I can not use mysql. I have installed de connector/J for mySQL version 3.1.12 When it is asked to restart JBoss in section 8.2.3, I have error when restart. If I try to do the "ant.. run-cmp" it doesn't work and I can't see the table which have been created. Has someone already had this problem? If you know a solution please help me! Is it possible that the connector is not correct with this version of mysql server? In this case which on do I use? Excuse me for my english but it's not my native language! Thank's!
