Ondrej Zizka [https://community.jboss.org/people/ozizka] modified the document: "MySQL module, datasource and persistence.xml (for Hibernate) configuration bash script" To view the document, visit: https://community.jboss.org/docs/DOC-19001 -------------------------------------------------------------- This is a bash script which will: Ask you for AS 7 directory, download MySQL JDBC driver, create a module for it, create myapp-ds.xml file using this module as a driver, create persistence.xml file using that datasource. What you need is to put the two files into your application's jar's  META-INF/  and change the datasource's connection-url, user-name and password. if [ "$1" == "" ] ; then   echo "  Usage:  $0 <AS7 dir>"   exit 1 fi AS_DIR=$1 mkdir -p $AS_DIR/modules/com/mysql/jdbc/main cd $AS_DIR/modules/com/mysql/jdbc/main wget http://cdn.mysql.com/Downloads/Connector-J/mysql-connector-java-5.1.21.zip unzip mysql-connector-java-5.1.21.zip rm mysql-connector-java-5.1.21.zip cp mysql-connector-java-5.1.21/mysql-connector-java-5.1.21-bin.jar . rm -rf mysql-connector-java-5.1.21/ cat <<EOF > module.xml <?xml version="1.0" encoding="UTF-8"?> <module xmlns="urn:jboss:module:1.0" name="com.mysql.jdbc">     <resources>         <resource-root path="mysql-connector-java-5.1.21-bin.jar"/>     </resources>     <dependencies>         <module name="javax.api"/>     </dependencies> </module> EOF cd - cat <<EOF > myapp-ds.xml <?xml version="1.0" encoding="UTF-8"?> <datasources xmlns="http://www.jboss.org/ironjacamar/schema"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://www.jboss.org/ironjacamar/schema http://docs.jboss.org/ironjacamar/schema/datasources_1_1.xsd">     <!-- JNDI at this location.
