s and development groups have evolved from the need to make business transactions more secure on the Internet. In doing so, business presence has grown exponentially over the last decade. Commercials on TV tell business owners if they aren’t on the web, they won’t survive. Programmers face difficult and exciting challenges in the areas of security for client/server transaction. One of the most popular languages used on the Internet is Java. Java runs on many different platforms, which makes it very versatile in Internet applications. JavaSoftTM has introduced the Java Commerce Client (JCC) framework. The JCC provides a secure, robust, and reliable platform that enables software vendors to write electronic commerce applications. With a framework, you focus on the application-specific business logic and let the framework handle the low-level programming details. Application-specific code is organized into modules called cassettes. A cassette represents one part (or module) of a transaction. Cassettes are mixed and matched to lay the foundation for an electronic transaction. A cassette designed by one vendor can interact with one or more cassettes by that same vendor or by agreement with a cassette from another vendor. The JCC framework orchestrates cassette interoperations and enforces the high level of security required for reliable transactions between clients and merchant servers. The framework and cassette innovation supports a full range of large and small money-based applications such as personal finance software, tax calculation programs, and retail sales applications--all of which can run on any Java-enabled platform with the JCC framework installed.The JCC framework consists of commerce-related classes, interfaces, and cassettes for you to implement your own application-specific electronic commerce code, and an environment within which the application code runs. Clients with an installed and configured JCC fra...
