Abstract: The software architecture of EEJBM is the two-layer distribute component software architecture. In order to gain the high performance for the remotely method invoking, it optimizes two points: the first is using register-provide method to get the high performance server’s location, the second is using EJBPOOL to initialize the EJB HOME’s connection beforehand. The forecasting arithmetic is discussed and analyzed in different area. The experimental results show that the new EJB software architecture can get good result in improving the performance and efficiency of distribute system.

摘要： EEJBM体系结构采用服务器路由和构件调用预测算法来提高EJB应用系统的效率，把优化的重点放在使用Register-Provid来提供高效服务器地址和使用EJBPOOL来缓冲EJB构件的连接过程。文中分析了3种EJBPOOL中的构件预测替换策略，并且讨论每个算法特性及其不同应用场景。实验结果表明，这种新的EJB体系结构有效地提高了分布式系统的性能。
