【摘要】 首先介绍了Web Senices的体系结构和协议栈;然后根据同步模式的缺陷,提出异步Web服务的解决思想,并描述了它在J2EE中的工作原理是通过缓冲和回调两种机制的结合来实现将客户端请求放入请求队列和将消息异步地发送回客户端。最后讲述了在J2EE中创建异步Web服务应用的过程,并描述了示例的工作过程。更多还原

【Abstract】 Firstly the architecture and protocol stack of Web Services are introduced. Then according to the disadvantage of synchronous mode, asynchronous Web Services is put forward; It’s principle in J2EE is also described that through combination of the two mechanism: buffering and callback, queuing client request into request queue and sending message asynchronously back to client are all implemented. At last, how to create asynchronous Web Services application and the working process of the example are also described.更多还原
