HibernateUtil.java:

package controller;

import org.hibernate.cfg.Configuration;
import org.hibernate.SessionFactory;

/**
 * Hibernate Utility class with a convenient method to get Session Factory
 * object.
 *
 * @author ROMO
 */
public class HibernateUtil {

    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from standard (hibernate.cfg.xml) 
            // config file.
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Log the exception. 
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

FindQuestion.java:

package controller;

import beans.Question;
import com.opensymphony.xwork2.ActionSupport;
import java.util.ArrayList;
import java.util.List;
import org.hibernate.Session;

/*

public class FindQuestion extends ActionSupport {

    private String q = null;
    private String categoryname = null;
    private List questionList = new ArrayList();

    @Override
    public String execute() throws Exception {
        q = "Question";
        categoryname = "Category";
        try {
            Session session = HibernateUtil.getSessionFactory().getCurrentSession();
            session.beginTransaction();
            this.questionList = (List<Question>) session.createQuery("from Question").list();
            session.getTransaction().commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return SUCCESS;
    }

}

Can someone please Help me out.

Answer 1

You have asm version that is incompatible with your Hibernate version. One way to check for compatible versions is to take a look to the maven dependencies, here for example for hibernate-core. It is usable way even if you do not maven builds.

One working combination for example is:

• Hibernate 3.6.10,
• cglib 2.2
• asm 3.1.

If you need answer that is more suited for you, you have to share information about which libraries are included at the moment.
