Hi, I am writing 4 different jsp's and just calling as "a", "b", "c" and "d". 4 jsp are inter-related, it means I have to enter the fields in a, validate in servlet and save the "a" content into database, then go to page "b", and so on. For 4 jsp's I have use 1 servlet to check for validation and save the date by 4 different methods. However, I don't know why one day I have create a new records, The data in "a", "b" and "d" page is save into my database, but the data in "c" disappeared! So anybody can tell me why??? Thanks for all replies!!!
