Problems solved by technology

Legacy applications are not so constrained by this, and, in fact, since it only has to be internally consistent, some legacy applications employ good programming techniques (for example, the suggested documentation and interface information), while other traditional applications do not
Rewriting legacy applications to adapt them to new computing environments is time- and resource-intensive, expensive, and introduces errors
[0009] As a result, existing systems suffer from undesired shortcomings and limitations

Abstract

A system and method incorporating existing or legacy software applications into a distributed data processing environment by encapsulating each legacy application into a new application which adheres to the Enterprise JavaBean (EJB) interface specifications. The new application with the EJB interfaces allows use of the application in a distributed processing environment such as the Internet or a virtual private network such as an intranet.
