PropertyChangeListener - Details

• 
  Key Concepts: 
  PropertyChangeListener is an interface in the BC-JAS Java Application Server that allows an object to be notified when a property of a bean changes. It is used to detect changes in the properties of a bean, such as when a user changes the value of a field in a form. 
  
  How to use it: 
  To use PropertyChangeListener, you must first create an instance of the interface and register it with the bean. This can be done by calling the addPropertyChangeListener() method on the bean. Once registered, the listener will be notified whenever a property of the bean changes. 
  
  Tips & Tricks: 
  When using PropertyChangeListener, it is important to remember to unregister the listener when it is no longer needed. This can be done by calling the removePropertyChangeListener() method on the bean. 
  
  Related Information:
