javax.naming.NameNotFoundException: Name is not bound in this Context Exception

When you are working with the JNDI look up, quite often you would encounter the javax.naming.NameNotFoundException thrown by your application. JNDI names are registered in the registery, if you try to access the name which is not registered or by the wrong format, you would get the javax.naming.NameNotFoundException. Lets look at the below code for accessing the JNDI names using InitialContext.

Context envEntryContext = (Context) new InitialContext().lookup("java:comp/env");
String mydata = (String)envEntryContext.lookup("varName");

When you run the above code, if the name “varName” not found under the context “java:comp/env”, then you will get the below exception. You have correct the name for fixing this issue.

javax.naming.NameNotFoundException: Name [varName] is not bound in this Context. Unable to find [varName].
