    Can't access java namespace

      Hi. I have deployed an old version of JForum, and I've declared its datasource like this:

      <xa-datasource>
 <jndi-name>forum</jndi-name>
 <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
 <xa-datasource-property name="ServerName">localhost</xa-datasource-property>
 <xa-datasource-property name="PortNumber">5432</xa-datasource-property>
 <xa-datasource-property name="DatabaseName">forum</xa-datasource-property>
 <user-name>test</user-name>
 <password>test</password>
 <transaction-isolation>TRANSACTION_SERIALIZABLE</transaction-isolation>
 <min-pool-size>1</min-pool-size>
 <max-pool-size>10</max-pool-size>
 <blocking-timeout-millis>5000</blocking-timeout-millis>
 <idle-timeout-minutes>15</idle-timeout-minutes>
 <security-domain/>
 <application-managed-security/>
</xa-datasource>


      When JForum tries to get the datasource reference, it gets a NameNotFoundException. The code is like this: 

      Context context = new InitialContext();
this.ds = (DataSource)context.lookup(SystemGlobals.getValue(ConfigKeys.DATABASE_DATASOURCE_NAME));


      Where the value returned by SystemGlobals.getValue(ConfigKeys.DATABASE_DATASOURCE_NAME) is "java:forum".

      If I access the JNDIView mbean from the JMX console, I can see the datasource correctly bound: 

      java: Namespace

 +- forum (class: org.jboss.resource.adapter.jdbc.WrapperDataSource)


      I also tried using a reference bound to the comp/env context of this app, using this inside jboss-web.xml: 

      <?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
 <resource-ref>
 <res-ref-name>jdbc/forum</res-ref-name>
 <jndi-name>java:forum</jndi-name>
 </resource-ref>
</jboss-web>


      And this inside web.xml: 

      <resource-ref>
 <description>Hibernate</description>
 <res-ref-name>jdbc/forum</res-ref-name>
 <res-type>javax.sql.DataSource</res-type>
 <res-auth>Container</res-auth>
</resource-ref>


      And again, it shows in JNDIView but I always get a NameNotFoundException when performing the lookup java:/comp/env/jdbc/forum: 

      java:comp namespace of the forum.war application:

 +- UserTransaction[link -> UserTransaction] (class: javax.naming.LinkRef)
 +- env (class: org.jnp.interfaces.NamingContext)
 | +- jdbc (class: org.jnp.interfaces.NamingContext)
 | | +- forum[link -> java:forum] (class: javax.naming.LinkRef)


      The only way I can make it work is by setting use-java-context to false in the datasource declaration, so the datasource is bound to the global context, and JForum can see it, but I'd like to avoid this.

      With a newer JForum version, this doesn't happen, but I think the JNDI lookup code is exactly the same, and any of the apps have JNDI specific configuration.

      Thanks in advance
