Widlfy 10 custom DataSource

Hello everyone,

(Sorry that some of the formatting is off - I don't know how to fix this)

I want to deploy my project to Wildfly Application Server. I have made it work, however now I do want to use something different than the default H2 database. Therefore I have created a new data source in standalone.xml:

 <datasource jta="true" jndi-name="java:jboss/datasources/MySQLDS" pool-name="MySqlDS" enabled="true" use-ccm="true">
<connection-url>jdbc:mysql://localhost:3306/mysqlds</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<driver>mysql</driver>
<security>
<user-name>root</user-name>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
<background-validation>true</background-validation>
<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
</validation>
</datasource>

Driver is also there: 

<driver name="mysql" module="com.mysql.driver">
<driver-class>com.mysql.jdbc.Driver</driver-class>
</driver>

My persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="primary">
<jta-data-source>java:jboss/datasources/MySQLDS</jta-data-source>
<properties>
<property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
<property name="hibernate.show_sql" value="false" />
</properties>
</persistence-unit>
</persistence>
Now when I click test connection in the Wildfly console the connection works.

However, whenever I run the server and deploy the project with IntelliJ I get this error:

[2016-06-01 06:09:08,304] Artifact software-engeneering-wildfly-archetype-ejb:ejb: Error during artifact deployment. See server log for details.
[2016-06-01 06:09:08,305] Artifact software-engeneering-wildfly-archetype-ejb:ejb: java.lang.Exception: {"WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.persistenceunit.\"software-engeneering-wildfly-archetype-ejb.jar#primary\" is missing [jboss.naming.context.java.jboss.datasources.MySQLDS]","jboss.persistenceunit.\"software-engeneering-wildfly-archetype-ejb.jar#primary\".__FIRST_PHASE__ is missing [jboss.naming.context.java.jboss.datasources.MySQLDS]"]}

Any help is greatly apreciated.

Thanks a lot in advance,
Christian
