Hibernate + PostgreSQL : relation does not exist - SQL Error: 0, SQLState: 42P01
- by tommy599
Hello,
I am having some problems trying to work with PostgreSQL and Hibernate, more specifically, the issue mentioned in the title. I've been searching the net for a few hours now but none of the found solutions worked for me.
I am using Eclipse Java EE IDE for Web Developers. Build id: 20090920-1017 with HibernateTools, Hibernate 3, PostgreSQL 8.4.3 on Ubuntu 9.10.
Here are the relevant files:
Message.class
package hello;
public class Message {
private Long id;
private String text;
public Message() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
}
Message.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

name="Message"
table="public.messages">
<id name="id" column="id">
<generator class="assigned"/>
</id>
<property name="text" column="messagetext"/>
</class>
</hibernate-mapping>
hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>

package hello;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class App {
public static void main(String[] args) {
SessionFactory sessionFactory = new Configuration().configure()
.buildSessionFactory();
Message message = new Message();
message.setText("Hello Cruel World");
message.setId(2L);
Session session = null;
Transaction transaction = null;
try {
session = sessionFactory.openSession();
transaction = session.beginTransaction();
session.save(message);
} catch (Exception e) {
System.out.println("Exception attemtping to Add message: "
+ e.getMessage());
} finally {
if (session != null && session.isOpen()) {
if (transaction != null)
transaction.commit();
session.flush();
session.close();
}
}
}
}
Table structure:
foo=# \d messages
Table "public.messages"
Column | Type | Modifiers
-------------+---------+-----------
id | integer |
messagetext | text |

If I copy/paste the query into the postgre command line and put the values in and ; after it, it works.
Everything is lowercase, so I don't think that it's that issue.
If I switch to MySQL, the same code same project (I only change driver,URL, authentication), it works.
In Eclipse Datasource Explorer, I can ping the DB and it succeeds. Weird thing is that I can't see the tables from there either. It expands the public schema but it doesn't expand the tables. Could it be some permission issue?
Thanks!
