Decrease of RMI Application Coupling Degree Based on Dynamic Proxy and Interceptor

Based on Java RMI framework, a new design is introduced to plug common services into RMI application without modifying the remote interface. 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.
