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.
And then to add a driver to standalone.xml:
<driver name="mysql" module="com.mysql.jdbc">
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
The script to save and then run:
if [ "$1" == "" ] ; then
echo " Usage: $0 <AS7 dir>"
exit 1
