Hello jacevedo,

This means that the webserver cannot find the file
9E4939D6F70F7AD3A85A3417B6F7E194.gwt.rpc. Try to locate it and check
that it is in the correct path (which should be the client package).
On the other hand the hosted mode jetty is problematic when it comes to
applications with non-trivial server parts - just as in your case where
you are using spring. I'd advise you to set up an independent server
instance (maybe a tomcat) and run the GWT dev mode with the -noserver
option.
