Using interceptors to enhance CORBA

The integration of distributed computing and the object model leads to distributed object computing, in which objects rather than processes are distributed across multiple computers. A well-established standard for distributed object computing is the Common Object Request Broker Architecture (CORBA). Previously, you would have had to create-and enable the application to use-the components that provide such additional capabilities. Using these components requires specialized knowledge and understanding of problems outside the application domain. With the advent of interceptors-non-application components that can alter application behavior-you can enhance CORBA applications at runtime with components whose operation is transparent to both the application and the CORBA framework, modifying application behavior without modifying the application or the CORBA framework.
