Hi all, i have a simple JPanel bean in my projects, now i want to drag my panel bean class into my jframe.

My panel bean class is like this:

public class BeanPanel extends javax.swing.JPanel {

/** Creates new form BeanPanel */
public BeanPanel () {
    initComponents();
    Session session=HibernateUtil.getSessionFactory().openSession();
}

This code seem to break the bean:

Session session=HibernateUtil.getSessionFactory().openSession();

When i try to drag the class into my JFrame bean i had this error message:

This component cannot be instantiated. Please make sure it is a JavaBeans Component

If i comment it all works fine. What is the reason of this?

Thanks.
