Errors by binding MySQL to JBoss 7.0 - mysql

Question

I'm trying to use MySQL with JBoss 7.0. I've changed the standalone.xml and added the driver and the dataresources inside of it, i've also added the module.xml file in the modules/com/mysql/main folder.
This is a part of standalone.xml:
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="H2DS" enabled="true" jta="true" use-java-context="true" use-ccm="true">
<connection-url>
jdbc:h2:mem:test;DB_CLOSE_DELAY=-1
</connection-url>
<driver>
h2
</driver>
<pool>
<prefill>
false
</prefill>
<use-strict-min>
false
</use-strict-min>
<flush-strategy>
FailingConnectionOnly
</flush-strategy>
</pool>
<security>
<user-name>
sa
</user-name>
<password>
sa
</password>
</security>
</datasource>
<datasource jndi-name="java:/mydb" pool-name="my_pool" enabled="true" jta="true" use-java-context="true" use-ccm="true">
<connection-url>
jdbc:mysql://localhost:3306/mydb
</connection-url>
<driver>
mysql
</driver>
<security>
<user-name>
root
</user-name>
<password>
</password>
</security>
<statement>
<prepared-statement-cache-size>
100
</prepared-statement-cache-size>
<share-prepared-statements/>
</statement>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>
org.h2.jdbcx.JdbcDataSource
</xa-datasource-class>
</driver>
<driver name="mysql" module="com.mysql">
<driver-class>
com.mysql.jdbc.Driver
</driver-class>
<xa-datasource-class>
com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
and the module.xml:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.39-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
And when i deploy (using eclipse) i get this error:
14:36:28,108 INFO [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-7) Deploying non-JDBC-compliant driver class com.mysql.jdbc.Driver (version 5.1)
