Simply put, it's a java class written in a certain way, according to a 
so called design pattern. If you do this, visual programming tools
such as NetBeans or JBuilder can read this class and put it on it's 
component-palette.

In practice it means: 

All attributes are private and there are get- and setmethods 
for changing them...

private integer value

public integer getValue(){ ... }
public void    setValue(integer newValue) { ... }

Events have their listeners named in a certain manner, meaning that 
the programmingtools can figure out which events the clas can send.

Also, if you for instance have a class/javabean named MyClass, you can
create a class MyClassBeanInfo which contains tailored info for
your javabean.
