• Eclipse Error: “Failed to connect to remote VM” 26 answers

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..

Which server are you using?

Like already said:

1. In your debug configuration you'll have to define the right port of your server (GF:9009 / Tomcat:8000)
2. You'll have to set the JVM property of the server to debug

For Glassfish:

    Log in to admin-console > Configurations > server-config > JVM-Settings > check DEBUG checkbox > restart server

For Tomcat:

create file debug.bat/.sh (depending on your OS) in %TOMCAT_HOME%/bin directory and write

    set JPDA_ADDRESS=8000
    set JPDA_TRANSPORT=dt_socket
    catalina.bat jpda start

in it.

After you've created this file start server by executing debug.bat/.sh.

Now you should be able to debug remotely in Eclipse after you set the necessary properties in your debug configuration.

Hope this helped! Have Fun!

EDIT

If you're running tomcat in a Win environment as a service you don't have a catalina.bat file in the bin-directory of your tomcat installation.
To set your server into debug-mode please try the following:

1. Run the Configuration option in Windows Menu or run %catalina_home%/bin/tomcat6w.exe
2. In Java tab, add this line to Java:

options:-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n

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

回答3:

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 :)

回答4:

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

回答5:

• 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.

回答6:

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!

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%

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.
