Re: is it possible to debug GWT projects (breakpoints, step through code etc) ?

Thanks for the suggestion Tim, I was really hopeful but I think I'm running in the Debug perspective but the breakpoints are still not triggering :-(

Did you open the debug view ? iirc in eclipse you need to

Hi,

Can anyone help me get remote jdwp server debugging in Eclipse working? I seem to be able to get a server running but it won't halt on breakpoints.

I run as.. "Maven Build" with goals of 'clean install appengine:run' and vm arguments of '-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8000'

The Console says "Listening for transport dt_socket at address: 8000"

Then I "Debug as..." "Remote Java Application"...

And the console starts up again with the 'clean install appengine:run' finishing up with the usual:

Started NetworkTrafficSelectChannelConnector {HTTP/1.1, (http/1.1)}{localhost:8080}

At which point I can browse to http://localhost:8080 but none of my breakpoints will trigger.

Please, what am I doing wrong? I've not done java remote debugging before :-(

Regards

Daniel

Thanks Ralph, So it's source map debugging in chrome for the client side, jdwp remote debugging for the server side.

Hi! Unless you want to invest time and effort in getting eclipse plugins up and running, I would suggest using your browser's development tools (Ctrl+Shift+I in Chrome/Edge) to debug the client side. Thanks to source maps it will show your JAVA source code when debugging. 

To debug the server side, you need to start your server with "-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n" and create a debug configuration to connect to port 8000 in Eclipse.

Good luck

Hi, 

Is it possible to debug GWT projects - setting breakpoints and stepping through code? This would be server and/or client debugging.

We've just had our internal GWT based app updated and it now uses maven to run (clean install appengine:run). The eclipse plugin based debugging technique that I used to use no longer seems to work.

Thanks for any advice, I really like GWT but I'm lost as to how it all works!
