I am using netbeans, and want to integrate struts and hibernate for a simple application to display all the data of a table on a jsp page.

But i am getting the following error

import org.hibernate.SessionFactory;

/**

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;
    }
}

    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;
    }

Simply add to your pom.xml :

<dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib-asm</artifactId>
        <version>1.0</version>
</dependency>

I found this:

http://www.hildeberto.com/2008/05/hibernate-and-jersey-conflict-on.html

Essentially, just in case the full explanation above goes: I Fixed classloading issues with asm by using the cglib-nodep-2.2.3.jar. The reason why this needs replacing is that ASM is a popular library. Hibernate is built against asm 1.5.3 but asm is now at version 4. Somewhere, the class loaders in my container are picking up a much more recent version of asm and the class ClassWriter has been changed. Hibernate uses cglib under the covers, which in turn uses asm 1.5.3. This is the issue. cglib-nodep was built to fix this issue. The asm classes have been moved from their standard package to a cglib package and it is these cglib versions that are used by the nodep library.

Spring adopts a very similar approach.

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.
