Hello Guice experts,
I'm very new to guice-servlet and love the concept - but I can't for
the life of me get it to work with my GWT project. I've not found any
references to this problem so I'm sure I must be doing something
wrong, and I really hope one of you can help me solve this before I
scurry back to my web.xml files!
My problem is this: I have a very simple GWT app that I've set up to
be injected from a (so far) completely empty ServerModule. When I try
to run this through the Eclipse GWT plugin I get an
IllegalAccessException. I'm using version 3.0 for guice and guice-
servlet, and GWT 2.4.
MyGuiceServletContextListener literally contains only this emptiness:
protected Injector getInjector() {
return Guice.createInjector(new ServletModule() {
protected void configureServlets() {
}
});
}
And my web.xml has the listener and GuiceFilter set up as per the
tutorial.
The error that gets thrown on startup is this:
java.lang.IllegalAccessError: tried to access field
com.google.inject.servlet.GuiceFilter.servletContext from class

This seems to relate to this line (and very interesting comments) from
GuiceServletContextListener:
41 // Set the Servletcontext early for those people who are using
this class.
42 // NOTE(dhanji): This use of the servletContext is deprecated.
43 GuiceFilter.servletContext = new
WeakReference<ServletContext>(servletContext);
So I wonder if there's a workaround for this.
Please, any help gratefully received!
Thanks,
Andy
