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.
Love is GOD and GOD is Love.
