Unable to run DevMode

[Raziel]

Hi, I just upgraded my application from 1.7.0 to 2.0, and while
everything is working fine in production mode, when I try to run
Development mode I get the following error:

I'm trying to run DevMode from Eclipse. I have to say my project
configuration is not "typical". Since my GWT application lives within
another application that requires logging in, previously in 1.7 I used
to point the start URL in the Debug Web Application configuration to
the address that pointed to the login page. So I just logged in and
navigated to my GWT application, and at that moment the breakpoint
weer hit and everything worked nicely.

However, now I don't know where to specify the start URL since the new
plug-in removed that field, and DevMode doesn't seem to be doing
anything and instead I get that exception.

Any ideas?

Thanks

I am having the same issue right now.

Can you verify that the jar file is intact? To do so, use the jar command to try and list its contents:

jar tvf   jmxtools-1.2.1.jar

GWT attempts to guess what the startup URLs are. It looks for the HTML and JSP pages that are direct children of your war folder, and generates startup URLs from them. If it does not find any files that match that criteria, no startup URLs will be listed. 

You can add the following program argument to your launch configuration to specify a startup URL:

-startupUrl <URL Fragment>

where <URL Fragment> is the path to a page (relative to the war directory) or a servlet.

The jar is untouched. I also have configured the startupUrl in my
eclipse plug-in Program Arguments. I can debug, however it only works
after the second time I put the address in the browser's address bar.
The first time I get that exception.

You can start properly the GWT 2.0 DevMode like it's described here:
