I'm currently Working on a GWT 2.4 / Spring 3 application and want to
use the RequestFactory API to communicate with Spring services.
I searched and find that to integrate GWT integrate with Spring
beginning from 2.4 you just need to create a custom ServiceLocator
that expose your Spring beans.
public class SpringServiceLocator implements ServiceLocator {
public Object getInstance(Class<?> clazz) {
ApplicationContext context =
WebApplicationContextUtils.getWebApplicationContext(
RequestFactoryServlet.getThreadLocalServletContext());
return context.getBean(clazz);
}
}
And you need to configure you RequestFactoryServlet as mentioned on
the Google documentation.
I followed theses steps but my when GWT client make a Request to the
Back-end i receive this Exception :
