Thank you for your feedback and support on this. I spent a very long time, trying many different combinations, including those you suggested, unfortunately none of them worked.
this topic was also discussed here, you can see my comments there. http://groups.google.com/group/google-web-toolkit/browse_thread/thread/20ea2aea53aa29d3 here is the log, showing whats going on ... http://paste.pocoo.org/show/308797/ based on your suggestion, I removed references to RequestFactoryServlet from web.xml and added this mapping to my webmvc-config.xml config file: <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <value>/gwtRequest=gwtRequestFactoryController</value> </property> </bean> <bean id="gwtRequestFactoryController" class="com.google.gwt.requestfactory.server.RequestFactoryServlet"/> from the log file, it is clear that /gwtRequest is mapped. I also tried dozen of other combinations, but unfortunately no luck. still don't know why GWT RequestFactoryServlet behaves like this in Spring configured environment ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
