Since you mention MySQL, the driver jar will be available here http://dev.mysql.com/downloads/connector/j/5.1.html. After you download that .tar/.zip, extract it to some folder. Inside that you will find a jar (ex: mysql-connector-java-5.1.8-bin.jar). Copy that jar to $JBOSS_HOME/server/default/lib anonymous wrote : | 2. i copied the sample from $JBOSS_HOME$/docs/examples/jca/mysql-ds.xml | to $JBOSS_HOME$/server/default/deploy-is this all i need to do?
