Hi Frnds,
I got the problem,
Iam trying to send a Default value NATIONALITY in setString
cs.setString(2,Nationality);
cs.setString(3,"NATIONALITY");
I have changed the lines to
String lookup_type="NATIONALITY"
cs.setString(2,Nationality);
cs.setString(3,"Lookup_type);
now i got the o/p, hope this may help others
