I successfully configured a datasource in my standalone.xml file,but I can´t get the same configuration to work in domain mode.Are there some change I need to apply?

My config looks as follows:

<datasource jndi-name="java:/datasources/OracleDs" pool-name="OracleDs" enabled="true" use-java-context="true">

                        <connection-url>jdbc:oracle:thin:@xxxx:1521:xxxx</connection-url>

                        <driver-class>oracle.jdbc.OracleDriver</driver-class>

                        <driver>oracle</driver>

                        <security>

                            <user-name>xxx</user-name>

                            <password>xxxxx</password>

                        </security>

                        <validation>

                            <validate-on-match>false</validate-on-match>

                            <background-validation>false</background-validation>

                        </validation>

                        <statement>

                            <share-prepared-statements>false</share-prepared-statements>

                        </statement>

                    </datasource>

                    <drivers>

                         <driver name="oracle" module="com.oracle">

                            <xa-datasource-class>oracle.jdbc.driver.OracleDriver</xa-datasource-class>

                        </driver>

                    </drivers>
