I have to develop a GWT webapp, which in deployment will need to run from a
standalone jar. To do this, I have a class with a main() method, in which
jetty is executed and the pages served.
However, since I need to debug what happens in the main() also in
development mode, so I'm looking for a solution that allows me to run the
DevMode while at the same time having a main() method.
I tried with a dirty solution - i.e., call DevMode by reflection, so if (as
in deployment) the class is not there, the standard jetty server is
executed:
try {
Class<?> cls = Class.forName( "com.google.gwt.dev.DevMode" );
Method meth = cls.getMethod("main", String[].class);
meth.invoke(null, (Object) args );
} catch (Exception e) {
runJetty( args );
}
While this initially seemed to work, I then realized that the GWT DevMode
seem to have its own ClassLoader, and all the REST methods and jetty
listeners are loaded by this ClassLoader, thus preventing me from acceccing
the initialization (e.g. some static variables) done in the main()
So what I want to understand is:
1) Is it feasible what I'm trying to do?
2) What's the correct way of running GWT's DevMode from a main?
3) How can I access the ClassLoader of GWT?
