    java.lang.NullPointerException
  2. 0

    Hi, I am trying to upgrade an application using Spring 3.06 and DWR 2.0.3 to Spring 4 latest version on tomcat 7. But when I start my app, I get below error on the console. The app works fine with Spring 3.2.8. I even tried moving to DWR 3 but get the same error. Is Spring 4 backward compatible with DWR 2 ?
