My client application looks like this
package pack1;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;

public class SpringHibernateTest {

/**

*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Resource resource=new FileSystemResource("src/pack1/spring-hibernate.xml");
BeanFactory factory=new XmlBeanFactory(resource);
Employee employee=new Employee();
employee.setAge(23);
employee.setId("12");
employee.setName("Dibakar");
employee.setSalary(1234.78);
EmployeeDao employeeDao=(EmployeeDao)factory.getBean("employee1Dao");
employeeDao.saveOrUpdate(employee);
Employee empresult=employeeDao.getEmployee("123");

System.out.println(empresult);
}
}
My employeeDao class:----
package pack1;

import java.sql.SQLException;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate3.HibernateCallback;
import org.springframework.orm.hibernate3.HibernateTemplate;

public class EmployeeDao {

private HibernateTemplate hibernateTemplate;

public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}


public Employee getEmployee(final String id)
{
HibernateCallback callback=new HibernateCallback() {

@Override
public Object doInHibernate(Session session) throws HibernateException,
SQLException {
// TODO Auto-generated method stub
return session.load(Employee.class,id);
}
};
return (Employee)hibernateTemplate.execute(callback);
}
public void saveOrUpdate(final Employee employee) {

HibernateCallback callback=new HibernateCallback() {

@Override
public Object doInHibernate(Session session) throws HibernateException,
SQLException {
// TODO Auto-generated method stub
session.saveOrUpdate(employee);
return null;
}
};
hibernateTemplate.execute(callback);
}
}

The exception is caused by "Caused by: java.lang.ClassNotFoundException: org.apache.common.dbcp.BasicDataSource". Ensure jar with this class is availaible.

It looks like you still are missing jars in the classpath.

Caused by: java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver

Is your Derby JDBC driver jar in your classpath.

I highly recommend reading up more on classpath and what it means in terms of having jars and classes in your classpath at compile time and also at runtime.

Thanks

Mark
