Remote Debugging with Eclipse / JBoss does not work any more

[Markus Schmider]

I start JBoss 6 M5 with
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n %JAVA_OPTS%
In Eclipse Eclipse Java EE IDE for Web Developers Build id: 20100218-1602
I have Remote Java Application Debug Configuration
Connection Type: Standard (Socket Attach)
Host: localhost
Port 8787
I have used this setup countless times before and it has worked.
I don't know what has changed. Now I keep getting
"Failed to connect to remote VM. Connection refused.
Connection refused: connect"
Restarting Eclipse and even rebooting has not solved this.
TCPView shows me that JBoss listens on port 8787.
I have also tried switching the port to no avail.

Any ideas what might cause this?

Many thanks Hans

The normal first question I'd ask is "Has someone set up a firewall"?

But you're using localhost, so unless the "localhost" network address in the hosts file has been tampered with, networking is probably not an issue.

You can see if the problem is in the client (Eclipse) or in the server (JBoss) by attempting connection with a different debugged. Shut down Eclipse to remove possible interference and fire up the Java command-line "jdb" application, aimed at localhost:8787
