How to lookup JNDI resources on WebLogic?

Question

I deployed a legacy application on WebLogic 11g. The application has the following code:

 Context context = new InitialContext();
 dataSource = (javax.sql.DataSource) context.lookup("java:myDataSource");

I also have a data source configured in WebLogic with the JNDI name of:

     jdbc/myDataSource

When the above java code runs, I get the following exception:

       javax.naming.NameNotFoundException: While trying to look up /myDataSource in /app/webapp/axis2.war/60105275.; remaining name '/myDataSource'
        at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1139)

      at weblogic.jndi.internal.ApplicationNamingNode.lookup(ApplicationNamingNode.java:144)

I'm fairly new to JNDI, so my question is? Where is the disconnect in naming? What does it mean when a context lookup has a prefix of "java:" ?

Thanks!

You should be able to simply do this:

Context context = new InitialContext();
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

If you are looking it up from a remote destination you need to use the WL initial context factory like this:

Hashtable<String, String> h = new Hashtable<String, String>(7);
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, pURL); //For example "t3://127.0.0.1:7001"
h.put(Context.SECURITY_PRINCIPAL, pUsername);
h.put(Context.SECURITY_CREDENTIALS, pPassword);

InitialContext context = new InitialContext(h);
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

weblogic.jndi.WLInitialContextFactory
