Hi James,
Thanks, I didnt see why it shouldnt take a String for
an Object, It accepted the string yesterday. Christmas
. . . .does wonders, doesnt it !!!!.
But, My JTable still gives a nullpointer exception, to
whichever row I try to insert my data into.
Should my JTable be initialised to some dummy values
or should I specifiy the dimensions of my JTable
before hand !!!!
Thanks a lot and enjoy your holidays,
Rao
