    Default Getting the beans property at runtime.

    I have made a bean component automatically created by netbeans.Then I bind a jtextfield's text property to that bean's property and in my main method I set the property for that bean.Yet, I m not getting the property name in my textfield after the program runs.Can anybody help.
    Here is the bean component that netbeans created for me by default.
    Java Code:
    package saraelectro;
    import java.beans.*;
    public class myBean implements Serializable {
        public static final String PROP_SAMPLE_PROPERTY = "sampleProperty";
        private String sampleProperty;
        private PropertyChangeSupport propertySupport;
        public myBean() {
            propertySupport = new PropertyChangeSupport(this);
        public String getSampleProperty() {
            return sampleProperty;
        public void setSampleProperty(String value) {
            String oldValue = sampleProperty;
            sampleProperty = value;
            propertySupport.firePropertyChange(PROP_SAMPLE_PROPERTY, oldValue, sampleProperty);
        public void addPropertyChangeListener(PropertyChangeListener listener) {
        public void removePropertyChangeListener(PropertyChangeListener listener) {
    This is my main method to set the property of that bean.
    Java Code:
    public static void main(String[] args) {
           myBean bn= new myBean();
           bn.setSampleProperty("This text should go into the jtextfield");
           myFrame frm=new myFrame();
    And that is what netbeans created after I bound jtextfield's text property to my beans' property.
    Java Code:
    bindingGroup = new org.jdesktop.beansbinding.BindingGroup();
    org.jdesktop.beansbinding.Binding binding = org.jdesktop.beansbinding.Bindings.createAutoBinding(org.jdesktop.beansbinding.AutoBinding.UpdateStrategy.READ_WRITE, myBean1, org.jdesktop.beansbinding.ELProperty.create("${sampleProperty}"), myTextField, org.jdesktop.beansbinding.BeanProperty.create("text"));
    WHY am I not getting that value of my bean in my textfield??
