Jess Wiki: Property Change Events

import java.beans.*;

public class JavaBean implements {
    private String m_val;

    public String getFoo() { return m_val; }

    public void setFoo(String val) {
        String tmp = m_val;
        m_val = val;

    public void addPropertyChangeListener(PropertyChangeListener pcl) {
    public void removePropertyChangeListener(PropertyChangeListener pcl) {
