Checkout http://docs2x.smartfoxserver.com/GettingStarted/howtos#item6.

In eclipse simply use "Remote Java Application" in the "Debug Configurations" dialog and setup your remote app to use the port you have configured in the extra debug parameters in your sfs2x.bat.

What I have described does exactly what you want. You start smartfox with the extra debug parameters, then register it in eclipse as remote java app. Then you can put breakpoints into your code within eclipse and see what happens.
You might also need to go into the Source tab in the remote app debug config and add your projects.

I've been doing it and it worked for me

Hi MKA,

When I connected my java extension code into debugging I got "Failed to connect to remote VM. Connection timed out.org.eclipse.jdi.TimeoutException" this exception.Please let me know step by step what u did.

Make sure the port you configure as debug parameter on smartfox matches the port you configure in your remote app in eclipse.

Eclipse uses port 8000 as default. The example uses 8787. So you either have to set eclipse to 8787 or smartfox to 8000. Also the host in eclipse needs to match the host you are running smartfox on.

Hi MKA,

Again I faced problem when I run my remote apps through debug mode.
"Failed to connect to remote VM
com.sun.jdi.connect.spi.ClosedConnectionException".

Please make me help for this

Hi Gopala,

I just encountered same issue but I fixed it thanks to MKA.

So, just try to create another ".bat" script (for example: sfs2x-debug.bat) where you can have the following:

@java -cp "./;lib/*;lib/Jetty/*;extensions/__lib__/*" -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n -Dfile.encoding=UTF-8 com.smartfoxserver.v2.Main $1 $2 $3

Then, run "sfs2x-debug.bat" instead of SFS running standalone or "by service".

In the end, simply setting on Eclipse -> Debug Configurations -> Remote Java Application of: Project (the one you are working), SFS IP machine (as host) and 8787 (as port) should be fixing that.

Hi, I use server version 2.0.0-RC1 and there's no JVM settings tab in the Server Configurator module of the admin...

Do you think you could help me set up the remote debug ?

Hi. Please update to SFS2x RC3, that's the latest one
