Hi guys! currently we're using hibernate 2.1.0 and its working fine. here's my mapping:


hibernate.hbm.xml

<hibernate-configuration>

<session-factory>
<property name="show_sql">true</property>
<!-- for mysql -->
<property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>


<!-- Mapping files -->
<mapping resource="hbm/Profession.hbm.xml"/>
<mapping resource="hbm/Sector.hbm.xml"/>
<mapping resource="hbm/ListingRole.hbm.xml"/>
<mapping resource="hbm/ListingType.hbm.xml"/>
<mapping resource="hbm/Industry.hbm.xml"/>
<mapping resource="hbm/ContactRole.hbm.xml"/>
<mapping resource="hbm/ListingEntry.hbm.xml"/>
<mapping resource="hbm/ListingSub.hbm.xml"/>
<mapping resource="hbm/ListingHeader.hbm.xml"/>
<mapping resource="hbm/Title.hbm.xml"/>
<mapping resource="hbm/ContactRelationship.hbm.xml"/>
<mapping resource="hbm/Contact.hbm.xml"/>
</session-factory>

</hibernate-configuration>

and stored in the folder /hbm (together with the class mappings)

I created a class called SQLManager that loads the configuration file and also responsible in creating the session


SQLManager.java

package com.eon.common;

import java.sql.SQLException;

public class SQLManager {

private static final String CONFIGFILE = "/hbm/hibernate.hbm.xml";
private String _configFilePath = null;
private static SQLManager _manager = null;
private SessionFactory _factory = null;
private DataSource _datasource = null;
private Configuration configuration = null;
private boolean isStandAlone = false;

private SQLManager() {

}

public void init() {
URL configFileURL = null;
try {

configFileURL = SQLManager.class.getResource(
(_configFilePath==null)?CONFIGFILE:_configFilePath);
configuration = new Configuration().configure(configFileURL);

_factory = configuration.buildSessionFactory();
Util.getLogger(this)
.debug("open connection "+_factory.openSession().isConnected());
} catch (HibernateException he) {
he.printStackTrace();
}
}



public void createTables() {
/* try {

new SchemaExport(configuration).create(true, true);

Util.getLogger(this).debug("Generated the Database");
} catch (HibernateException he) {
he.printStackTrace();
}*/
}

public static SQLManager getInstance() {
if (_manager == null)
_manager = new SQLManager();
return _manager;
}

public void setSessionFactory(SessionFactory sf) {
_factory = sf;
}

public SessionFactory getSessionFactory(){
return _factory;
}

public Session getSession() throws HibernateException,SQLException {
if (_datasource == null)
return _factory.openSession();
else {
Util.getLogger(this).debug("new connection");
return _factory.openSession(_datasource.getConnection());
}
}

public void setDataSource(DataSource datasource) {
_datasource = datasource;
}

............

}


Here's the problem, when we migrated to hibernate2.1.2 im getting this error:

and its complaining on this line:
configuration = new Configuration().configure(configFileURL); ???

We want to migrate to the new version because of its new features but is hibernate2.1.2 stable already?Any help guys?

thanks...

solved it already. i just deleted all my jar files in \lib and paste the new jar.
