Can't debug in eclipse in development mode with GWT 2.0 RC1

[Youen]

Hi,

I'm testing GTW 2.0 RC1 and I don't know how to debug (in eclipse)
when i am in development mode.

I set some breakpoints, I run in eclipse debug mode and I use firefox
3.5, but it seems that the breakpoints are not catch.

Does someone make it work or am I missing someting ?

Regards,

[Jason Parekh]

Hi Youen,

Which version of Java are you using?  There was an issue where breakpoints would not catch on JDK 1.6.0_14.

You can check the version being used under: 
- Run > Run configurations 
- Expand Web Application on the side bar 
- Select one of its children, click on the JRE tab

Hi Youen,

Could you also make sure the launch configuration is using 1.6.0_15?  It could be the case that your default JDK is _15, but when the launch config was created, it was using _14.

Have breakpoints every work for you in this project?  How about more generally in other projects in Eclipse?

Ok in eclipse it's written that it is the default Mac OS X JDK, so it
should be the _15 version.

I make further tests and :
- Breakpoints work on a project from scrath!
- Breakpoints do not work with my 2 main (big) gwt project.

The main difference with my 2 project is that the main html file is a
Velocity template managed with spring MVC (so there is no main HTML
file in my war folder).

I'll investigate on the problem (if you have any ideas ...i'll take
them).

I suspect a problem between SpringMVC and GWT 2.0 rc1. Within the same
projet, same class path, if I load my app from a static html file it
works but if I load my app with a generated html from freemarker and
springMVC I've got a "[ERROR] [gwtdemo] Unable to find
'gwtdemo.gwt.xml' on your classpath; could be a typo, or maybe you
forgot to include a classpath entry for source?".
Looks like the moduleloader is not the same.
Any Idea ?

There is a known issue with RC1 that might be the cause of this.  Specifically the last one listed in known issue section of http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC.  Even though your app does not use App Engine, the issue is really that a GC pass before the browser load request comes across can invalidate some weak refs.  This has been fixed in the trunk and 2.0 branches.

In my case, removing all references to spring mvc resolved the
problem. When I go down to the code, the problem is in a method called
nestedLoad.
It calls URL moduleURL = classLoader.getResource(resName);
This one return null in some case because resName is provided without
package classLoader.getResource('foo.gwt.xml') => null ,
classLoader.getResource('com/foo/Test/foo.gwt.xml') => not null Url

I will need to restore the spring config, any idea ? I should try to
compile the last trunk?
