关于改进Web Services调用机制的研究

现行的Web Services技术的服务调用过程是基于XML的SOAP协议.随着Web Services应用范围的扩展,对其服务性能提出了更高的要求,但由于XML的自身特性,限制了Web Services作为分布式计算技术在事务级领域的应用.首先概述了Web services的总体框架,然后基于Web Services的性能评判标准,分析了Web Services的性能现状,并结合EJB技术、数字证书技术和紧耦合集成技术,从系统调用机制角度对Web Services加以改进.最后阐述了改进调用机制的特点和适用范围.

Research on improving mechanism of web services transfer

The process of services transfer by web services technique is based on SOAP protocol,which is developed from XML.With the range of the web services extending,more demands of its function are expected.Butweb services,a distributed computing technique,is limited in transaction-level application by some shortages of XML.The framework of web services is introduced,and then on the basis of judging web services function criterions,its current situation is analyzed.A novel of web services transfer mechanism is pren-sented,which is combined with some techniques ofEJB(enterprisejavabean),digital certification and tightly concatenating integration.Finally,the characteristics and the application areas of this transfer mechanism are expounded.
