Hey all

I am new to Spring and learning the DI. I have three simple classes for an experiment.

Class1:



Class2:



Class3:



Beans.xml:



But as pointed in code, it keeps giving me NPE. Even using @Autowired in Class3 gives error. Please suggest what am I doing wrong?

EDIT:

If I dont set the scope to be prototype, it works fine. Else it doesn't.
But I need the scope to be prototype since I want this bean to have a new instance everytime its launched (I am calling it using a button click. But I did not include that code for sake of simplification).
 
Let me tell you a story about a man named Jed. He made this tiny ad:
