I am not a java programmer but am working on a project that uses hibernate to store data.

When i execute my file i get an error :

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lo
gging/LogFactory
at net.sf.hibernate.cfg.Configuration.<clinit>(Configuration.java:94)
at net.ttg4me.data.UpdateCps.main(UpdateCps.java:23)
Press any key to continue...

I believe this error is due to improper classpath. However i have tried everything i possibly could to set the classpath..but without any success.

If i try compiling Configuration.java i get exactly a 100 errors all saying something to the effect :
D:\net\sf\hibernate\cfg\Configuration.java:24: package org.apache.commons.logging does not exist
-> import org.apache.commons.logging.Log;

Apache server is installed on my server
Please help..

Here's my sample code:

package net.ttg4me.data;

import net.sf.hibernate.Session;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.*;
import net.sf.hibernate.transaction.*;
import net.sf.hibernate.cfg.Configuration;


// use as
// java test.InsertProduct name amount price
public class UpdateCps {

public static void main(String[] args)
throws Exception {
try
{
// 1. Build a Product
CpsBrep p = new CpsBrep();
p.setRejcode("sachin");

// 2. Fire up Hibernate
Configuration cfg = new Configuration()
.addClass(CpsBrep.class);
SessionFactory sf = cfg.buildSessionFactory();

// 3. Open Session
Session sess = sf.openSession();

// 4. Save Product and close Session
Transaction t = sess.beginTransaction();
sess.save(p);
t.commit();
sess.close();
}
catch (Exception ex)
{
System.out.println(ex);
}
}
}

it is 100% certain that you are missing commons-logging.jar from your classpath (and posibly others)


btw. why does your subject say net.sf not found and your contents talk about commons-logging classes ?
