Saving hibernate object throws IllegalArgumentException
I'm attempting to save a hibernate-generated class in a servlet using jboss 4.0.2 and the Java 1.5.0.03 jdk. Can anyone shed light on why the following doPost method fails at (1) below with an IllegalArgumentException exception (ERROR [BasicPropertyAccessor] expected type: java.lang.Long, actual value: java.lang.Long)? I've included the console output, server.log, Address.hbm.xml, hibernate-service.xml, and the generated Address.java. Thanks in advance.
public class DataServlet extends HttpServlet {
protected void doPost(
HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
...
try {
session = HibernateUtil.currentSession();
tx = session.beginTransaction();
Address address = new Address();
address.setStreet("home");
(1) session.save(address);
tx.commit();
} catch(PropertyAccessException e){
(2) szErrorMsg = e.getMessage();
tx.rollback();
} finally {
}
...
e.getMessage() at (2) above returns ...
