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 ...
