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");
