[java] Eclipse : Failed to connect to remote VM. Connection refused.

When ever i tried to launch my eclipse debug(for server side code) i'm getting the following error Failed to connect to remote VM. Connection refused.

What's the problem may be? I already tried with most of the solutions out in the web but none of that solved my issue. Could any one can assist me to fix this? Advance thanks..

As suat said, most of the time the connection refused is due to the fact that the port you set up is in use or there is a difference between the port number in your remote application debugging configuration in Eclipse and the port number used in the address attribute in

-Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n.

Check those things. Thanks!

Sometimes the port which you are trying to access, gets occupied and won't be released. Try some tools to find whether the port is in use or not. I also faced the same issue. I tried giving different port numbers but unfortunately it didn't work. I tried restarting the system (not the application server), and it worked :)

I ran into this problem debugging play framework version 2.x, turned out the server hadn't been started even though the play debug run command was issued. After a first request to the webserver which caused the play framework to really start the application at port 9000, I was able to connect properly to the debug port 9999 from eclipse.

[info] play - Application started (Dev)

The text above was shown in the console when the message above appeared, indicating why eclipse couldn't connect before first http request.

If you need to debug an application working on Tomcat, make sure that your Tomcat-folder/bin/startup.bat (if using windows) contains the following lines:

set JPDA_TRANSPORT="dt_socket"
set JPDA_ADDRESS=8000

call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS%

when you have Failed to connect to remote VM Connection refused error, restart your eclipse

• The port number in the Eclipse configuration and the port number of your application might not be the same.

• You might not have been started your application with the right parameters.

  Those are the simple problems when I have faced "Connection refused" error.

I faced the same issue. But i resolved it by changing my port numbers to different one.
