Mysql DataSource on Jboss AS7

The connector can be downloaded from: http://dev.mysql.com/downloads/connector/j/. The current version at the time of writing is 5.1.17, further sections of this guide assume that version number.

Unzip the connector to your downloads folder and save the location of the main JAR in a variable which we can refer to later:

cd /Downloads unzip mysql-connector-java-5.1.17.zip export MYSQL_JAR=/Downloads/mysql-connector-5.1.17/mysql-connector-java-5.1.17-bin.jar Add a Module to AS 7

AS 7 uses a module system to provide isolation in class loading. We need to create a new module which contains the MySQL Connector J JAR. Move to the the AS installation directory and create the folder structure for the new module:

export JBOSS_HOME=~/Development/jboss-as-web-7.0.0.Final cd $JBOSS_HOME mkdir -p modules/com/mysql/main Copy the driver jar to the new directory and move to that directory:

cp $MYSQL_JAR $JBOSS_HOME/modules/com/mysql/main cd $JBOSS_HOME/modules/com/mysql/main Define the module in XML. This is the key part of the process:

vi module.xml If the version of the jar has changed, remember to update it here:

The new module directory should now have the following contents:

module.xml mysql-connector-java-5.1.17-bin.jar Create a Driver Reference

Now the module has been created, we need to make a reference to it from the main application server configuration file:

cd $JBOSS_HOME/standalone/configuration vi standalone.xml Find the ‘drivers’ element and add a new driver to it:

org.h2.jdbcx.JdbcDataSource The ‘h2? driver is part of the default JBoss configuration. The new driver that needs adding is named ‘mysql’.

Add the Datasource

Go into the configuration directory and open the main configuration file:

cd $JBOSS_HOME/standalone/configuration vi standalone.xml Find the datasources element and add a new datasource inside:

jdbc:mysql://localhost:3306/mydb mysql root 

    </password>
