1 A BeanBox is a visual interface that displays (and allows changes to be made to) the properties of a JavaBean and further allows one to see and change the linkage between JavaBeans.
2 A JavaBean consists of Java Code and possible associated files such as one or more icons, an image or two, a help file etc. This collection of entities is stored in a jar file which is based on the well-known UNIX tar file concept
3 JavaBeans are naturally used as distributed objects in CORBA and can be linked to both JDBC (and hence databases) and COM from Microsoft.
4 There is a Java native distributed communication model RMI (Remote Method Invocation) which provides CORBA like capabilities for a pure Java world
