Did you set JAVA_OPTS correctly in the JBoss run batch file?

After running that, open another command window and do

telnet localhost 8787

and let me know what you get

If you didn't get

Could not open connection to the host, on port 8787: Connect failed

then check the Eclipse setting for the correct host and port on the remote debug options

jwdp port (here 8787) is not concurrent. Once you have a client connected to this port, other client would get connection refused. You need to make sure that eclipse debugger is the only application connecting to this port at a time.

If you're still having a problem, can you post the result of

netstat -an | find "8787"

I think you should shut down what's already apparently connected, debugging-wise

Eclipse is open source and you have freedom to develop your plugins, and you will find a lot of open source plugins of eclipse
