Hi.,

I ve this piece of code for the JNDI lookup in the Weblogic server 7.0 and i ve implemented this in the init() method of the Java Applet.I am getting the exception(in the client console) as given below.

This is the code:

Properties initialContextProperties = new Properties();
try {
initialContextProperties.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
String host=null;
InitialContext InitialContext;
String url = "t3://localhost:7001" ;
initialContextProperties.put(Context.PROVIDER_URL, url);
initialContextProperties.put(Context.SECURITY_PRINCIPAL, "xxx");
initialContextProperties.put(Context.SECURITY_CREDENTIALS, "yyy");
InitialContext = new InitialContext( initialContextProperties );
}catch( NamingException e ) {throw e;}


this is the exception i am getting--

throws:
javax.naming.CommunicationException. Root exception is java.net.ConnectException: No server found at T3://localhost:7001

Substitute localhost with the IP address or hostname of your machine and see if it works.


SCJP 1.4, SCWCD 1.3, SCBCD 1.3
 
It is sorta covered in the JavaRanch Style Guide.
