Below is the function that i m using on two scnerio.
1st Scnerio. ============= Just click on add button make entry into required fields and click Save Button.
I call this function before saving data into database. If i am calling this function within the form (Class A) then it is working fine and good.
2nd Scnerio =========== I have 3 classes i.e. Class A, Class B and Class C
While working on Class A i am calling Class B and filling all kind of required data from Class B to global vector in Class C. After setting data from Class B to another Class C via vector, I close down Class B and again going to Class A as it is already opened.
On clicking a single button in Class A to fill my JTable from Class C (Vector), my all data is appearing and working fine.
But while saving as the below function is called i got an error on "Statement" statement i.e. Java.lang.NullPointerException.
System.out.println("Test"); This is not printed.
Can any one tell me why I am getting this error as the same is working in 1st Scnario.

It looks the problem may be with your connection.
Before you try that line, try printing cnnd with System.out.println(cnnd) to see if it's null.
