Problem to get j2ee server context

[tushars]

Hi,
I am integrating my application with weblogic 6.1 server. When I try to access the context of Weblogic server, I am getting the following exception.

javax.naming.AuthenticationException [Root exception is java.lang.SecurityException: attempting to add an object which is not an instance of java.security.Principal to a Subject's Principal Set]

The Client program is running properly if I run the client program from the Weblogic server machine. If I try to run the client program from another machine, then it is giving this problem.

Please help me regarding this problem. Thanks in advance.
Regards
Tushar

- open Weblogic Console
- select your server domain name
- select 'Security'
Check 'Guest Disabled' check box.
--------
checked - guest does not have permission to access WL
unchecked - guest has permission
---------
---------
But,also you can access WL from guest user with username/password [ if default guest is disabled ]
ex.
----------------------------
private T3ServicesDef getT3Services(String wlUrl)
throws javax.naming.NamingException
{
T3ServicesDef t3s;
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, wlUrl);
env.put(Context.INITIAL_CONTEXT_FACTORY,weblogic.jndi.WLInitialContextFactory.class.getName());

if( m_username!= null && m_password != null )
{
//Make sure that the value for
//the Context.SECURITY_AUTHENTICATION property is one
// of the valid values
//("none", "simple", or "strong&quot.
//simple Use weak authentication
//(clear-text password)
env.put(Context.SECURITY_AUTHENTICATION, "simple"
env.put(Context.SECURITY_PRINCIPAL, m_username );
env.put(Context.SECURITY_CREDENTIALS, m_password );
}
Context ctx = new InitialContext(env);
t3s = (T3ServicesDef) ctx.lookup("weblogic.common.T3Services"
ctx.close();
return(t3s);
}
