Strange Hibernate Behaviour

Hello,

I had the following codes with does not show me any error at all and there is no updates/insert
into the database:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

import com.theta.code.Addrtyp;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.MappingException;
import net.sf.hibernate.Session;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;

public class InsertACodeTest {

	private static Configuration cfg = null;
	private static SessionFactory sf = null;
	private static Connection conn = null;
	private static Session se = null;
	private static Addrtyp at = null;

	public static void main(String[] args) {
		try {
			loadDBConnection();
			loadConfiguration();
			loadFactorySession();
			loadSession();
			testInsert();
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			System.gc();
		}
	}

	private static void loadConfiguration() throws MappingException {
		cfg = new Configuration().addFile("Addrtyp.hbm.xml");
	}

	private static void loadFactorySession() throws HibernateException {
		sf = cfg.buildSessionFactory();
	}

	private static void loadDBConnection()
		throws
			ClassNotFoundException,
			IllegalAccessException,
			InstantiationException,
			SQLException {
		String sJDBCdriver = "COM.ibm.db2.jdbc.app.DB2Driver";
		String sDBurl = "jdbc:db2:LOS_DB";
		String sUserID = "db2admin";
		String sPassword = "db2admin";
		Class.forName(sJDBCdriver).newInstance();
		conn = DriverManager.getConnection(sDBurl, sUserID, sPassword);
	}

	private static void loadSession() {
		se = sf.openSession(conn);
	}

	private static void testInsert() throws HibernateException {
		at = new Addrtyp();
		at.setCode("999");
		at.setDesc("test 999");
		at.setStatus("A");
		at.setDescEnglish("bla");
		se.saveOrUpdate(at);
	}
}
and the XML file is like this:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<class 
    name="com.theta.code.Addrtyp" 
    table="CODE.ADDRTYP"
>

    <id
        name="code"
        type="java.lang.String"
        column="CODE"
    >
        <generator class="assigned" />
    </id>

    <property
        name="desc"
        type="java.lang.String"
        column="DESC"
        length="50"
    />
    <property
        name="status"
        type="java.lang.String"
        column="STATUS"
        length="1"
    />
    <property
        name="descEnglish"
        type="java.lang.String"
        column="DESC_ENGLISH"
        length="100"
    />

    <!-- associations -->

</class>
</hibernate-mapping>

Can anyone tell me whats wrong? All I could get is these 2 lines:

log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

Does these warning won't update/insert anything into the database?

Thanks

Neo
