• Spring 3 MVC and JSON example

These are very good comments from mkyong:

When Spring sees

1. Jackson library is existed in the project classpath
2. The mvc:annotation-driven is enabled
3. Return method annotated with @ResponseBody

Spring will handle the JSON conversion automatically.

If we see something like this:

HTTP ERROR 406

Problem accessing /kfc/kfc-kampar. Reason:

    Not Acceptable

We probably forgot the Jackson library. Or the POJO doesn't have a getter-methods.
