I have a working standalone application which accesses one of the default queues ("queue/A"). Now I'm trying to get the same thing working from an applet on a web page on the local web server.

I'm using JBoss 3.0.4, with /etc/hosts configured properly, i.e., xxx.xxx.xxx.xxx myhostname

and i access the applet over my web server at http://myhostname.

The applet looks up a UILConnectionFactory over JNDI, and then attempts to make a queue connection via createQueueConnection. This is where it fails. Here's the partial stacktrace I have (I can't figure out how to see all the exceptions in the Java Control Panel!)..

my code is very simple, in the applet's start() method:

try {
jndiContext = new InitialContext(env);
} catch (NamingException e) {
System.out.println("Could not create JNDI API " +
"context: " + e.toString());
System.exit(1);
}

try {
queueConnectionFactory = (QueueConnectionFactory)
jndiContext.lookup("UILConnectionFactory");
queue = (Queue) jndiContext.lookup(queueName);
} catch (NamingException e) {
System.out.println("JNDI API lookup failed: " +
e.toString());
System.exit(1);
}

try {
queueConnection =
queueConnectionFactory.createQueueConnection("guest","guest");

I get an error on the above line... please note that my stand-alone client works without any username/password in the above method. I simply added the above default user combination since the error below says someting about permissions...

Any thoughts? I'd very much appreciate any and all ideas/suggestions!!

Thanks much in advance!
