Can't register Oracle jdbc driver

Hello all,

I am testing Jboss EAP 7.0 on Redhat 7, and want to connect backend Oracle 11g r2, so I downloaded ojdbc6.jar driver from http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html .

I already added this ojdbc6.jar new core module in CLI by the following command:

module add --name=com.oracle --resources=/root/ojdbc6.jar --dependencies=javax.api,javax.transaction.api

In EAP_HOME/modules/com/oracle/main/ directory have the following files:
module.xml ojdbc6.jar

Below is module.xml :

And then want to register the JDBC driver in CLI by the following command , but failed:

/subsystem=datasources/jdbc-driver=oracle:add(driver-module-name=com.oracle.jdbc,driver-name=oracle,driver-xa-datasource-class-name=oracle.jdbc.xa.client.OracleXADataSource)
{
"outcome" => "failed",
"failure-description" => "WFLYJCA0041: Failed to load module for driver [com.oracle.jdbc]",
"rolled-back" => true
}

I am following the following guideline:

Thanks
