When I still used Eclipse I always used the plugin from  Brandon 
Donnelson :  https://github.com/gwt-plugins/gwt-eclipse-plugin 

On that GitHub mainpage is a link to a YouTube playlist (under Reference). 
Just watch those and you should know everything you need to know about 
working with the plugin/superdevmode/breakpoints.

It should just work.  Like many other tools out there, SuperDevMode uses 
JavaScript source maps (the old way used plugins, which are no longer 
allowed in most browsers).  If you debug your app in Chrome dev tools, the 
source you will see will be your Java code in the debugger (not the 
compiled JS code).

All the SDBG plugin does, is hook into Chrome so you can debug in Eclipse, 
instead of needing to use the Chrome dev tools debugger.

Maybe create a new hello world app, just to see how it works:

Re: GWT Server and debug

2020-07-10 Thread Jasper Suijker 
Gwt by default converts my(your) code to javascript (JS). With the "old" 
browser plugin we were able to add breakpoints in the client java code and 
when running the app, the debugger stopped at those points.
I understand, that when running in superdevmode, this works differently.
Does anyone has een extended example on how to set this superdevmode up and 
do the debugging with browser's developer tools?

Re: GWT Server and debug

2020-07-08 Thread Jasper Suijker 
Hi,

This SDBG plugin assumes you are using the gwt plugin in eclipse.
We have our projects as "normal" java projects and when we want to test, we
run an eclipse launch with the correct parameters.

I have tried converting the project to a gwt project, but then a run into
(gwt) classpath errors, which i am not able to fix.
If i want to debug the application in web and not use Internet explorer, i
need to use the eclipse plugin or is there an other way?

regards,

Jasper

Run the code using Debug as and Choose Open With SDBG Chrome JS Debugger

It will trigger breakpoints

I also had the same problem few weeks ago but using that helped so Try it

Re: GWT Server and debug

2020-07-07 Thread Jasper Suijker 
Ok,
I removed  -nosuperDevMode and started the server via debug of eclipse.
I made some breakpoints in the code, but somehow they are not triggered.
With the plugin and using internet explorer i see a "unknown" tab showing
in the GWT development Mode. But when running "just" in the superdevmode i
don't see that.
Maybe i am missing or using a configuration in one of the xml files, which
is preventing debugging?

Re: GWT Server and debug

2020-07-06 Thread Thomas Broyer 
gwt.codesrv is a sign that you're using the deprecated so-called "classic" 
DevMode, that relies on a browser plugin, that indeed only works in 
Internet Explorer nowadays.
If you haven't already, then first upgrade to at least GWT 2.7.0 (of course 
2.9.0 would be a lot better),
then you'll be able to use SuperDevMode the same way as you're used to run 
DevMode, except you don't have to install any plugin: just load the page in 
your browser and it'll automatically trigger the compilation of your code.
Your code will then run in JS in your browser, and you'll debug it from 
your browser's developer tools, leveraging source maps (Chrome or Edge work 
better, likely Safari too; Firefox used to be sluggish but that was 
supposed to be better in recent versions, haven't tried it yet though).
See http://www.gwtproject.org/articles/superdevmode.html to learn more 
about SuperDevMode.

GWT Server and debug

2020-07-06 Thread Jasper Suijker 
LS,

We are using GWT to get our Swing gui available in web.
This works nicely. After compiling, we deploy our application in tomcat and
it runs and shows the same screens as we have in Swing.

Now we want to debug the web parts through the gwt Jetty server. (GWT
development mode)
To be able to debug, you Start the jetty server and it will give you a url
like: http://127.0.0.1:/?gwt.codesvr=127.0.0.1:9997
The part after the question mark is the magic of the GWT server, being able
to debug your code. As far as i know this only works in Internet Explorer,
is that correct?

Internet Explorer is terrible to work with, the javascript engine is
terrible and large memory usage, etc
Microsoft is already pushing users towards Edge, so Internet explorer will
stop at some point..
Is there another way to debug GWT?

Regards,

Jasper
