Research on Performance Optimization in J2EE Resource Integration
J2EE资源集成的性能优化研究

Based on JCA specification, J2EE Application Server gives a standard way to integrate enterprise re- sources. Under the connector architecture, the application server provides different services, including transactions, security and connection management for resource adapters, and these services are important to the system perfor- mance. This paper studied several problems in application server's resource integration implementation, including connection management and transaction management. Some available optimizations and the implementations are giv- en. These optimizations have been successfully employed in the J2EE Application Server OnceAS.
