Hi there,
I am trying to modify Laliluna's sample of Struts and Hibernate to insert customer when typing in Book information.
In bookAdd.jsp, I can get all customers in drop down box, after I type in all fields and select one customer, and submit, it says
Quote:
argument type mismatch
. it is right, the customer returned from jsp is integer, but in Book.hbm.xml, it must be Class Customer, how can I make it works?
I researched many days and couldn't get it. your any input will be appreciated.

Code:
Postgre SQL ScriptCREATE TABLE customer( id serial NOT NULL, firstname text, lastname text, age int4, CONSTRAINT customer_pk PRIMARY KEY (id)) ;CREATE TABLE book( id serial NOT NULL, title text, author text, customer_fk int4, borrowallowed bool NOT NULL DEFAULT true, CONSTRAINT book_pk PRIMARY KEY (id)) ;ALTER TABLE book ADD CONSTRAINT book_customer FOREIGN KEY (customer_fk) REFERENCES customer (id) ON UPDATE RESTRICT ON DELETE RESTRICT;
Book.hbm.xml
Code:
