I have a problem running my gwt2.4rc1 application in a tomcat. The problem occurs when I try to make a requestfactory call. Then I get the exception at the bottom.
When I run GWT in development mode everything works fine. The gwt-dev. jar is in the lib folder of my webapp. I am using maven for dependency management. Could there be a problem with my configuration? I already had the error with gwt2.4 beta. If there are any other information required to solve this problem I am glad to provide them.
Regards, Arne

There's a fix for this on its way over from RC to trunk. In the mean time, remove gwt-servlet from your dependencies and use requestfactory-servlet.jar instead.
