Clearly, its better to have TNS set up properly.

My question is why am I getting the following exception when jboss 4.0.4 is restarted or when I redeploy the application:

org.jboss.deployment.DeploymentException: Error during deploy; - nested throwable: (javax.naming.NamingException: resource-ref: DCDEV has no valid JNDI binding. Check the jboss-web/resource-ref.)

NOTE: The application is an exploded(unpacked) format. Not sure if i'm using the correct technical wording.

<reference-ref>
<res-ref-name>DCDEV</res-ref-name>
<jndi-name>java:/DCDEV</jndi-name>

Is this a typo? If not, it should be:

<resource-ref>
<res-ref-name>DCDEV</res-ref-name>
<jndi-name>java:/DCDEV</jndi-name>
</resource-ref>

Have you resolved this issue. I am having this same issue...

[djhititup]

Thank you so much for catching that tag name problem; however the issue still remains. My code below still doesn't work.

out.println("<H1>VERSION 2 w/ DataSource of DCPROD</H1>");
Connection con2 = null;
try {
InitialContext context = new InitialContext(null);
DataSource source = (DataSource)context.lookup("DCDEV"); // DOES NOT WORK
//DataSource source = (DataSource)context.lookup("java:/DCDEV"); // DOES WORK
con2 = source.getConnection();
out.println("DONE!");
} catch (Exception ex) {
out.println("NO SUCCESS BECAUSE " + ex.getMessage() + "");
//ex.printStackTrace(new PrintWriter(out));
} finally {
if (con2 != null) {
con2.close();
out.println("AND WE CLOSED IT!");
}
}

DataSource source = (DataSource)context.lookup("DCDEV"); // DOES NOT WORK

The reason why this wont work is because, by default the datasources are bound in the java: namespace. If you want it to be bound in the global namespace then add the following statement to your ds configuration file(i.e. oracle-ds.xml)

<local-tx-datasource>
 <jndi-name>DCDEV</jndi-name>
 <use-java-context>false</use-java-context>
 ......
 <!-- All your other stuff -->

</local-tx-datasource>

Correct me if I'm wrong but isn't JBoss to bound the datasource to java:/ and then within your application using the web.xml and jboss-web.xml you bound it to a global reference within your application? If this is so why would i use that setting to bound it to a global reference from within JBoss when I only want a global reference from within my application?

Are you talking about the resource-ref thing in web.xml and jboss-web.xml? If yes, then thats not the way it works. When you specify a resource-ref, you are binding the resource to the *application's java:comp/env jndi namespace* and *NOT* the global jndi namespace

Thank you for the information. If you feel froggy I have more forum post. :D
