This design improves the mechanism of RMI, which is based on dynamic proxy and interceptor technology. The implementation of class loader and stub is custom. The design ensures both the integrity of RMI mechanism and the plug-ins of some common services that are based on component. The design improves the modularization of application and decreases the coupling degree among different modules; by this means these middle-ware's modules gain more scalability and flexibility.展开更多

The algorithm with which some kinds of parameter type in DELPHI language can be converted into JAVA data representation is described. And how to use the object-oriented programming method to organize a class module of parameter conversion which is clear in hierarchy, unanimous in form and easy to generate is also discussed.展开更多

In addition to this model, we define remote server objects as session or entity objects according to their roles in a distributed application server, which separate information details from business operations for software reuse. A web store system is implement by using this multi-tier distributed object enterprise computing model.展开更多
