Exception trying to create InitialContext

Question

I am using the following code for trying to post a message to JMS queue using JDeveloper 11.1.1.5. Sometimes i get exception at the step of creating InitialContext.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL,"t3://xxxx:yyyy");
env.put(Context.SECURITY_PRINCIPAL,"username");
env.put(Context.SECURITY_CREDENTIALS,"password");
Context jndiContext = null;
try {
jndiContext = new InitialContext(env);
} catch (NamingException e) {
System.out.println("Could not create JNDI API context: " +
e.toString());
System.exit(1);
When i run the above code i get the following exception(seen in log window)
Could not create JNDI API context: javax.naming.CommunicationException [Root exception is weblogic.socket.UnrecoverableConnectException: [Login failed for an unknown reason: ]
When i checked the request and response using http analyzer the response is as follows.
JDeveloper HTTP Analyzer encountered an error retrieving:
CONNECT https://140.84.233.133:8001 HTTP/1.0
An exception occurred while retrieving the response for https://140.84.233.133:8001.

I have included weblogic.jar,wlclient.jar files in project libraries. The server is up and its listening port is running fine. Should i make any changes to my project settings?
Any help is greatly appreciated.
Thanks

Answer 1

The explanation is probably that the weblogic.jar and wlclient.jar are not meant to be compatible. For a description of different client options, see [WebLogic Server Client Types and Features|http://docs.oracle.com/cd/E17904_01/web.1111/e13717/basics.htm#SACLT126]. I highly recommend using the "thin t3 client" option for most use cases.
HTH,
