Can't find mysql.jdbc.Driver - MySQL, JBoss - mysql

Question

I'm unable to deploy my web app with MySQL 5.5.11 backend to JBoss 5. I get this error:
Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver from BaseClassLoader#262b2310
I pasted my stack trace below.
Here's what I've done...
I added mysql-connector-java-5.1.14-bin.jar to {JBOSS_HOME}/lib (that connector should work with MySQL 5.5.11 right?). I also added mysql-ds.xml to {JBOSS_HOME}/server/default/deploy.
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/my_libl_db</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>test</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
</local-tx-datasource>
</datasources>
Also, I made sure the mysql-connector-java-5.1.14-bin.jar in my lib folder is in my web apps classpath. In the JBoss Admin Console, under Resources/Datasources, I do see MySqlDS with a status of up.
My project (in Eclipse Indego Release) is an Enterprise Application Project with 1 Dynamic Web Project. The web app has has an #Entity bean and a #Stateless bean. The #Stateless is being injected to a servlet (using #EJB). Here's my persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
<persistence-unit name="ContactBookPersistUnit" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/MySqlDS</jta-data-source>
<class>com.contact.model.Contact</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
What could I be doing wrong?

Answer 1

This bit of documentation says you need to add the JAR to the /lib file in your default server configuration:
http://docs.jboss.org/jbossas/getting_started/v4/html/db.html
UPDATE: JBOSS 6 and newer has been rewritten to be more modular. You have to add JBDC drivers to your /module directory.
