JBOSS 7 MYSQL missing dependencies error - mysql

Question

There are many threads like this one already for similar errors but none which have solved my problem so after an hour of trying to debug it, I have decide to ask for help.
Background
I am setting up a Java EE project. I have create an enterprise application and have create an EJB project, JPA project and web Project and added EAR's to the enterprise project.
I have also added mysql-connector-java-5.1.0-bin to the JBOSS/standalone/deployments folder. And added to this jar file to the JPA project.
Any advice on how to solve the error would be greatly apprecited.
The main error is:
missing/unavailable dependencies" =>
["jboss.persistenceunit.\"SIMSProject.ear#primary\"jboss.naming.context.java.jboss.datasources.SIMSD
Here is my full error:

Answer 1

You need to create MySQL driver module.
JBoss 7 will be able to use if you create it like this:
download the driver (jar file)
create directory in you server path: {$jboss-home}/modules/com/mysql/main
and paste the driver jar file here
in same folder create and new file module.xml
Insert following code in that module.xml (if your jar file is named mysql.jdbc.jar):
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql.jdbc.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
Make sure the dependencies for your mysql.jdbc.jar are OK.
JBoss 7 is not using -ds.xml any more.
You allready doing setup for your databse in standalon.xml, this the right way.
Just make sure your migration is correct. I see you have diffent user name and password...
EDIT1:
I don't know how hibernate works with JBoss 7.
But I see you should try to change in your persistence.xml
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
to
<property name="hibernate.connection.driver_class" value="com.mysql"/>
because you are using com.mysql as module name. Otherwise you can change module name to com.mysql.jdbc.Driver.
In your standalone.xml
change
<driver>mysql-connector-java-5.1.0-bin.jar</driver>
to
<driver>com.mysql</driver>
because you gave com.mysql as name for your driver:
<driver name="com.mysql" module="com.mysql">
