I marked the code which works fine in the NEW version and also the old code (Commented)...
I just copy it to the new Location ( @ the start of the first Else Block) and there it works fine... plz tell me... WHY?
Probably THE JVM BUG or JAVA BUG....?
ONE MORE THING: It is working coz i have used the integer to locate the column named: "pay_Date"...no ....I have tried both ways ...it is just not working at the end of the else block...whatever u tried i won;t work...whichever column u tried to display it won't work...but if u write it in begining of the else block works..... ;( ;)
More replies to this thread would be appreciable and helpful for the JAVA Community... :)
