Deploy your MySQL database as C:\jboss-4.0.1sp1\server\devcon\deploy\mysql-ds.xml (as you did)
Leave C:\jboss-4.0.1sp1\server\devcon\deploy\jms\mysql-jdbc2-service.xml ALONE !!!! This is for JMS not CMP Either list you MySQL database as the default in jbosscmp-jdbc.xml (as you did), or specify it explicity in your persistence.xml like this: <persistence> | <persistence-unit name="jsEntities"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/bookingDatasource</jta-data-source> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/> | <property name="hibernate.transaction.flush_before_completion" value="true"/> | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="true"/> | </properties> | </persistence-unit> | </persistence> Obviously the <jta-data-source> name has to match the JNDI name used in mysql-ds.xml Hope this helps View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3926771#3926771 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3926771 ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
