HELP! Can't connect to 1099?

[mcjava1967]

Hi folks. When my new JBoss 4.2 Eclipse plugin starts, I'm getting this in the event log:

JMXException: Could not obtain connection to any of these urls: localhost:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]

I've tried switching the port to something like 1234, to be sure it wasn't in use, but I get the same error. The server itself does come up, but it seems I can't use JNDI for this reason.

I'm a newbie at JBoss, so there's a good chance I missed something obvious. If anyone could point me in the right direction on this, I'd really appreciate it. I've been trying to get started here for a couple weeks!


Thanks!

What does the following command output:

telnet localhost 1099

Do you have any firewalls installed? The firewall application might be blocking the requests.

[mcjava1967]

It shows this:

Connecting To localhost...Could not open a connection to host on port 1099 : Connect failed

I have Norton installed. Trying to shut it off an retry...

Will let you know in a minute. THANKS FOR RESPONDING !

[mcjava1967]

OK. Turned off Norton. Now I get this a message that interspersed with a lot of unprintable characters, which I can't copy and paste. This is the message with "..." in place of all the unprintables:

...java.rmi.MarshalledObject...hashlocBytest...BobjBytesq...Kur...sr org.jnp.server.NamingServer_Stub...xrjava.rmi.server.RemoteStub...java.rmi.server.RemoteObject...pw4...UnicastRef2 127.0.0.1

Connection to host lost.



Are we getting warm?

Yup, looks good now. Now try out your application. It should get past that Receive timed out error.

[mcjava1967]

I hate to say it, but I'm getting the same message. I have Norton turned off--both internet and anti-virus. To be sure, I shut down the JBoss server within Eclipse, shut down Eclipse, ended all java tasks in Task Manager, and restarted. But still get same message.

I am very grateful you're helping me out. Could you suggest a next step?

Thanks again...

I should mention in my previous post, I didn't highlight the last line:

connection to host lost

Is that normal?

Is that normal?

Yes, that should not be a problem. It's normal.

I have Norton turned off--both internet and anti-virus.

There was a similar post earlier where the user had run into a similar issue. Even after stopping the firewall, the ports were being blocked. Finally, he uninstalled the firewall and got it working. Here's that thread:

See if uninstalling your anti-virus/firewall software does the trick.

I'll give it a try. It's sunny and I'm officially on vacation today, so it may be tomorrow before I respond again. But again, thanks...

[mcjava1967]

Well, if you're still listening on my port...

I did not uninstall Norton (too scary), but I'm now getting the "successful" response to your command:

telnet localhost 1099

This is with Norton actually on, doing all it's regular things.

However, I'm still getting the original response when I try to run my "Hello World" application.

Would you have another suggestion for that?

Again, I'm very much a newbie. I'm not even sure I should be running the "Client" using "Run as...Java Application".


I really hope you're still listening. Any more help you could give me would be greatly appreciated !

[jaikiran]

However, I'm still getting the original response when I try to run my "Hello World" application.

I believe, you have a standalone Java client from which you are doing a JNDI lookup. Can you post the code where you doing the lookup? Let's see if everything is correct, there. And please post the entire exception stacktrace.

[mcjava1967]

Will try to respond tomorrow. Am getting some success now, which is very encouraging. But I'm not sure I've got it right...

Thanks!
