Hello, Can anyone please help me out on the below? I am new to GWT and I have been trying a lot to get a starter app running using GWT, Spring and hibernate.
I was able to set up basic app but now I want to use RequestFactory with Spring MVC. After searching a lot I came across few links to get started but I am not able to completely figure out how to get the configuration right, and my app is not working :( . Can anyone please suggest me where I can get a sample app with RequestFactory and SpringMVC configured so that I can get the settings right. Or help me to get my app running. I had followed the instructions given in http://jsinghfoss.wordpress.com/2011/08/10/gwt-2-2-0-requestfactory-spring-3-0-x-integration/ . I am using GWT 2.4 and spring 3.

And the call to findEmployee throws a null pointer exception. The locators I am using are attached in the mail. Please help me resolve this.
