I have a simple Hibernate code. The query does not work in the sense that even though the table has entries,nothing is returned. Any help is appreciated. I am using Hibernate 3.2 and Cloudscape 10.1

Hibernate.cfg.xml

</hibernate-configuration>

Query code
--------------

ackage app.proj.practice.beans;

import java.util.List;

import org.hibernate.Session;

public class PracticeManager {


public List listQuestions()
{

Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
List result = session.createQuery("from Category").list();
session.getTransaction().commit();
return result;

}
/**
* @param args
*/
public static void main(String[] args)
{
PracticeManager pracMgr = new PracticeManager();
List questions = pracMgr.listQuestions();
int size = questions.size();
System.out.println("Size:" + size);
for ( int i = 0; i < size; i++ )
{
Questions question = (Questions)questions.get(i);
System.out.println("Question Id:" + question.getQuestionId());
System.out.println("Question Desc:" + question.getQuestionDesc());
System.out.println("-------End of Record-------------------");
}

}

}


output:
-----------
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Hibernate: select category0_.CATEGORY_ID as CATEGORY1_0_, category0_.CATEGORY_NAME as CATEGORY2_0_ from CATEGORY category0_

Thanks,
