Unable to define oracle datasource on Jboss AS 7

I'm using Jboss AS 7.1.1.final and I'm trying to add an oracle Datasource:

<datasource jndi-name="java:jboss/datasources/DefaultDS" pool-name="DefaultDS" enabled="true" use-java-context="true">
                 <connection-url>jdbc:oracle:oci@TNS_NAME</connection-url>
                 <driver>oracle</driver>
                 <security>
                     <user-name>username</user-name>
                     <password>pwd</password>
                 </security>
             </datasource>
 

And the driver:

<driver name="oracle" module="com.oracle.ojdbc">
    <xa-datasource-class>oracle.jdbc.OracleDriver</xa-datasource-class>
 </driver>
 

But when i start the server i get:

JBAS014775:    New missing/unsatisfied dependencies:
   service jboss.jdbc-driver.oracle (missing) dependents: [service jboss.data-source.java:jboss/datasources/DefaultDS] 
 

I have a module under modules/com/oracle/ojdbc/main:

<module xmlns="urn:jboss:module:1.0" name="com.Oracle.ojdbc">
 <resources>
     <resource-root path="ojdbc6.jar"/>
    </resources>
   <dependencies>
     <module name="javax.api"/>
   </dependencies>
 </module>
 

and of course the jar is there.

Can someone please tell me what am I doing wrong here?
