My WAR packages a JAR in its WEB-INF/lib. And the JAR has persistence.xml in its META-INF. My persistence.xml contents are per the instructions in Wildfly JPA wiki -

<persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <non-jta-data-source>java:jboss/datasources/PostgresqlDS</non-jta-data-source>

        <class>in.bharathwrites.models.Test</class>

        <properties>

            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>

            <!--<property name="hibernate.show_sql" value="true"/>-->

            <property name="hibernate.hbm2ddl.auto" value="update"/>

            <property name="hibernate.format_sql" value="true"/>

        </properties>

</persistence-unit>

So, as you can see I use Postgres. Have configured the datasource in my standalone-full.xml as shown here -

            <datasources>

                <datasource jta="true" jndi-name="java:jboss/datasources/PostgresqlDS" pool-name="java:jboss/datasources/PostgresqlDS_Pool" enabled="true" use-java-context="true" use-ccm="true">

                    <connection-url>jdbc:postgresql://localhost:5432/dfadohirbu33sv</connection-url>

                    <driver>postgresql</driver>

                    <security>

                        <user-name>postgres</user-name>

                        <password>mypassword</password>

                    </security>

                </datasource>

                <drivers>

                    <driver name="postgresql" module="org.postgres">

                        <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>

                    </driver>

                </drivers>

            </datasources>

In the JBoss Management console, under datasources I can see listed my Postgres datasource with JNDI as java:jboss/datasources/PostgresqlDS. When I test the connection its all fine. Despite this, I get this exception and my deployment fails. What could I be doing wrong?
