Hi there,
I have 2 tables book and customer, and mapping files, the table book is associated to customer with many-to-one. In the jsp file, which is to insert new book, if I want to insert customer when I input book. I can get all customer info from table and list them in drop down box, when I click save to save the book with customer, it is supposed the bean of customer should be passed with book bean, but in my code, only customer id is passed. How can I fix the problem?
Thanks for your any reply.
