Spring Hello World prog
1 Answer(s)      4 years and a month ago
Posted in : Spring


I used running the helloworld prog code mentioned in

http://www.vaannila.com/spring/spring-mvc-tutorial-1.html

I'm getting null pointer exception. as shown below. I added all the jars and my folder structure is similar to what showed in the website. I guess the null pointer exception is because the redirect.jsp is not forwarding the request. Is it because I have my dispatcher-servlet.xml in web-inf folder? i dont find any <init> method in the web.xml file, is it the reason I'm getting nullpointer exception. please let me know.

Thanks,
