A JCA 1.5 resource adapter might contain config properties in ra.xml. It is not possible in JBoss to override them with -ds.xml file.

For example, here is an excert of SwiftMQ's intraVM ra.xml:

<resourceadapter>
<resourceadapter-class>
com.swiftmq.connector.v15.ResourceAdapterImpl
</resourceadapter-class>

<config-property>
<config-property-name>ProviderURL</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value>smqp://intravm/timeout=10000</config-property-value>
</config-property>
<config-property>
<config-property-name>IntraVM</config-property-name>
<config-property-type>java.lang.Boolean</config-property-type>
<config-property-value>true</config-property-value>
</config-property>
<config-property>
<config-property-name>DebugMode</config-property-name>
<config-property-type>java.lang.Boolean</config-property-type>
<config-property-value>false</config-property-value>
</config-property>
<config-property>
<config-property-name>RouterWorkingDirectory</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value><swiftmq_dir>/scripts/unix</config-property-value>
</config-property>
<config-property>
<config-property-name>ConfigurationFilename</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value>../../config/router1/routerconfig.xml</config-property-value>
</config-property>

It is not possible to overwrite them during deployment. It is only possible to specify the config properties of the ManagedConnectionFactory in -ds.xml.
