Sorry for making a new post, but I have stripped down my mapping file and classes, and am still getting no output from my program.
Hibernate version:
2.1
Mapping documents:
This document works:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping schema="ADMSTDDE">
<class name="Client" table="DEXA010T">
<id column="CLIENT_ID" name="id" type="string">
<generator class="assigned"/>
</id>
<property column="NAME" name="name" type="string"/>
</class>
</hibernate-mapping>
I don't get anything clients to print at all, by just adding the ClientGroup to the mapping file....there is no code change at all:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping schema="ADMSTDDE">
<class name="Client" table="DEXA010T">
<id column="CLIENT_ID" name="id" type="string">
<generator class="assigned"/>
</id>
<property column="NAME" name="name" type="string"/>
</class>
<class name="ClientGroup" table="DEXA020T">
<id column="CLIENT_GROUP_ID" name="id" type="integer">
<generator class="sequence"/>
</id>
</class>
</hibernate-mapping>
Code:
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
List result = session.find("from Client");
for (int i = 0; i<result.size(); i++) {
Client theClient = (Client) result.get(i);
System.out.println("Client id: " + theClient.getId() + " Name: " + theClient.getName());
}
System.out.println("\n" + result.size() + " Clients.");
tx.commit();
sessionFactory.close();
Here is Client.java:
Code:
public class Client {
private String id = null;
private String name = null;
private List clientGroups = new ArrayList();
// Getters and Setters below
}
Here is ClientGroup.java:
Code:
public class ClientGroup {
protected int id;
private Client client = null;
private String name = null;
// Getter and Setters below;
}

After that there is nothing else in the console. The program will run for a while longer, but it doesn't print any sql, or pull anything back from the database.
