I've got a problem with my web application, running on Firefox and built with Play!1.2.7, GWT2.6 on Windows 7. I'm using Eclipse Kepler as IDE.
First of all, in production mode, the application works. The problem is to make it work in dev mode, which enables debug configuration. The plugin GWT for Firefox that enables dev mode is not supported by recent versions of firefox, therefore, we use the "Super Dev Mode" plugin instead.
If I get it right, we have to launch the application first, then the super dev mode plugin.
First, to launch the application, in a command line, at the root of the application, we do a
play start
Then, to launch the dev mode, in Eclipse, we configure a run configuration for a java application:
Project: MyWebApp
Main class: com.google.gwt.dev.codeserver.CodeServer
Program arguments: -src app/ App -workDir C:\Users\user\workspace\MyWebApp\
classpath, user entries:
gwt-dev-2.6.0.jar - \MyWebApp\lib
gwt-user-2.6.0.jar - \MyWebApp\lib
gwt-codeserver-2.6.0.jar - \MyWebApp\lib
app - - \MyWebApp\
src - C:\play-1.2.7\modules\gwt2-1.8\
play-1.2.7 - C:\
When I run this java application, I have the following error:
