Eclipse – How to debug a connection failure between Jboss and eclipse debugger

debuggingeclipsejbossjvmlsof

I have setup eclipse to attach to a local JVM. But when I try to do the same for a machine over the network I get "connection timed out exception".

How do I go about debugging this issue?

I tried:

lsof -i :8787 on the remote machine, and it appears that a java process is in fact listening on that port.

What else could be wrong and how to go about finding it. Please help.

Thank you.

Note: My JAVA_OPT looks like this on the remote machine.
JAVA_OPTS=”-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n $JAVA_OPTS”

Servers often have multiple NICs; you might add the hostname or IP of the remote interface you're using to your debugging options, like so: -Xrunjdwp:transport=dt_socket,address=HOSTNAME_OR_IP:8787,server=y,suspend=n
