Can datasource be configured in standalone-outsystems.xml to use it in java extension

Can datasource be configured in standalone-outsystems.xml to use it in java extension

I need to connect a database in Java Extension, can we configure the datasource in standalone-outsystmes.xml and get it in java extentsion by jndi look-up. I am using Outsystems 9 with JBoss eap 6.

I am getting below error while doing this, please let me know if am doing something wrong here? do i need to modify any other file to make it work?

Configuration details:
1) Created module
module.xml file content-
<module xmlns="urn:jboss:module:1.1" name="oracle.jdbc">
        <resource-root path="ojdbc6.jar"/>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>

2) Added subsystem for datasource in profile 
Standalone-outsystems.xml datasource part-
<subsystem xmlns="urn:jboss:domain:datasources:1.1">
<datasource jndi-name="java:jboss/datasource/AR_SHR" pool-name="AR_SHR" enabled="true">
<driver name="oracle" module="oracle.jdbc">
I notice that you're trying to connect to an Oracle database.

Why not simply use the OutSystems Platform Database Connection functionality to achieve this?

They wanted a more complex connection scenario than the built-in conenction configuration allows. I don't know the details. They figured it out and we documented internally.
