Hi. I've been trying to simply crete a user and store data into MySQL.
I've been getting the mapping exception but I'm not sure where to look to fix this problem since my JUnit test runs fine and adds data to MySQL. I'm also using Jetspeed.

Any tips or suggestions would be very appreciate it.

Hibernate version: 3.0

Mapping documents:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.adsmack.framework.domain">

<class name="User" table = "user">
<id name="userId" column = "userId" type="integer">
<generator class="native"/>
</id>
<property name="userName"/>
<property name="displayName"/>
<property name="pwd1"/>
<property name="pwd2"/>
<property name="email"/>
<property name="firstName"/>
<property name="lastName"/>
<property name="birthDate"/>
<property name="address"/>
<property name="city1"/>
<property name="city2"/>
<property name="province"/>
<property name="country"/>
<property name="post"/>
<property name="sex"/>
</class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():

User theUser = new User(userName, displayName, pwd1, pwd2, email, firstName, lastName, birthDate, address, city1, city2, province, country, post, sex);
Session s = factory.openSession();
Transaction tx = s.beginTransaction();
s.save(theUser);
tx.commit();
s.close();
return theUser;

Name and version of the database I am using:
MySQL 4.1.12

Odds are decent that your mapping file isn't on your classpath. Open up your WAR/EAR file and make sure that User.hbm.xml is where you expect it to be.

Thanks for your reply. User.hbm.xml is in my classpath.
I forgot to mention that I'm using portlet. I was able to add data using hibernate when I ran my test class. So I think the problem might exist with my portlet. I get the error on s.save(theUser) line. Any replies would be very appreciate it.

Can you query users from within the Portlet ?

If not, make sure that you have the mapping element -

in your hibernate.cfg.xml file.

Data cannot be inserted into the table at this point. User.xml is in my configuration file. I also gave credits to those who replied to me. It seems like it's missing something but I just don't know what...
Thanks for any tips in advance.

Everything I see looks correct.

Can you enter data manually, and then try and query it ?

Thanks for your quick reply. Yes, my JUnit class runs fine and inserts data into the table. So I'm guessing this isn't really a mapping issue?? But I'm new to Hibernate so I could be wrong.

I would look at how your SessionFactory is being configured - in the Portlet code - and make sure it's finding and loading the classes/mappings.

Also, if you have data in the database you are using, can you just try and code a simple query against it and see if it retrieves the rows correcly ?

It won't (always) throw an exception on a query, it just won't return any results.
