Question: Difference between java Beans and Enterprise Java Beans?

Answer: ► JavaBeans may be visible or nonvisible at runtime.For example, the visual GUI component may be a button,list box,graphic or a chart. An EJB is a nonvisual ,remote object.
► JavaBeans are intended to be local to a single process and are primarly intended to run on the client side.Although one can develop server-side JavaBeans,it is far easier to develop them using the EJB specification instead. EJB's are remotely executable components or business objects that can be deployed only on the server.
► JavaBeans is a component technology to create generic Java components that can be composed together into applets and applications. Even though EJB is a component technology,it neither builds upon nor extends the original JavaBean specification.
► JavaBeans have an external interface called the properties interface, which allows a builder tool to interpret the functionality of the bean. EJBs have a dployement descriptor that describes its functionality to an external builder tool or IDE
► JavaBeans may have BeanInfo classes,property editors or customizers
