Not Able to Connect Prod OIM

I have a code that actually able to connect to Lab OIM but same code i am not able to connect to Prod OIM. Below is the code i am using. Did i miss anything? I have all those Jars also in my Project build path. Help and any suggestion will be appreciated. Below are the code and error i am getting after debugging the class.

 public class ConnectionTest {
         UserManager userManager;

          public ConnectionTest() {
                  super();
                }
   public static void main(String[] arg) throws IOException, Exception {

    ConnectionTest oim=new ConnectionTest();
    oim.OIMConnection();
}
 public void OIMConnection(){             
    Hashtable<Object, Object> env = new Hashtable<Object, Object>();
    env.put(OIMClient.JAVA_NAMING_FACTORY_INITIAL, "weblogic.jndi.WLInitialContextFactory");
    env.put(OIMClient.JAVA_NAMING_PROVIDER_URL, "t3://hostname:port");
    System.setProperty("java.security.auth.login.config", "C:\\Documents\\authwl.conf");
    System.setProperty("OIM.AppServerType", "wls");  
    System.setProperty("APPSERVER_TYPE", "wls");
    oracle.iam.platform.OIMClient oimClient = new oracle.iam.platform.OIMClient(env);

    try {                        
        oimClient.login("username", "password".toCharArray());         
        logger.info("Successfully Connected with OIM!\n");
    } catch (LoginException e) {
        CharArrayWriter cw = new CharArrayWriter();
        PrintWriter w = new PrintWriter(cw);
        e.printStackTrace(w);
        logger.error("Login Exception: "+ cw.toString());
    }            
    userManager = oimClient.getService(UserManager.class);
}}

Error I am getting is here.....

1. Check username and password.
2. Get wlfullclient.jar from Prod(not Lab).
3. Check C:\Documents\authwl.conf. It is Prod's file?

refer my sample:

public static final String OIM_HOSTNAME = "oim.hpt.lab";
public static final String OIM_PORT = "14000";
public static final String OIM_PROVIDER_URL = "t3://"+ OIM_HOSTNAME + ":" + OIM_PORT;
public static final String OIM_USERNAME = "tungpt";
public static final String OIM_PASSWORD = "Hpt123456";
public static final String OIM_CLIENT_HOME = "F:/designconsole11gr3/config";
public static final String AUTHWL_PATH = OIM_CLIENT_HOME + "/authwl.conf";

public static void main(String[] args) {
    // TODO Auto-generated method stub
    OIMClient oimClient = null;
    try {
        //Set system properties required for OIMClient
        System.setProperty("java.security.auth.login.config", AUTHWL_PATH);
        System.setProperty("APPSERVER_TYPE", "wls");

        // Create an instance of OIMClient with OIM environment information  
        Hashtable env = new Hashtable();
        env.put(OIMClient.JAVA_NAMING_FACTORY_INITIAL, "weblogic.jndi.WLInitialContextFactory");
        env.put(OIMClient.JAVA_NAMING_PROVIDER_URL, OIM_PROVIDER_URL);
        oimClient = new OIMClient(env);

        // Login to OIM with the approriate credentials
        System.out.println("Login by: "+ OIM_USERNAME);
        oimClient.login(OIM_USERNAME, OIM_PASSWORD.toCharArray());
        System.out.println("Login Done!");
    }catch(Exception e){
        e.printStackTrace();
    }
}
