Hi,

I m struck with Aspect J. I m new in this and i want to check Non Null for different pojo classes. 

My requirement is to check not-null for some field in different classes

for example: 

public class student{

private String a;

private String b;

                         }

public class teacher{

private String c;

private String d;

                         }

In these classes fields a and d should not be null.

How to implement this with AspectsJ

Thanks in advance. P;ease provide me solution of this.
