摘　　要：SOA架构使得下一代软件系统具有分布式、面向服务和动态配置和部署的特点,这种软件架构引起了Internet从传统的eyeball web到transactional web的发展趋势。但是Web浏览器在功能上过于单一,缺乏离线操作和对相关应用程序的API支持,从而人们开始研究和开发比Web浏览器功能更为丰富的胖客户端。文中提出了一种客户端自主更新与适配远程服务接口的智能客户端(Smart Client)框架。该框架在本地维护了一个服务连接池,这使得客户端对常用服务的绑定和访问在一定程度上可以不通过UDDI或LDAP自行完成,这样降低了客户端访问UDDI或LDAP的开销,减轻了UD-DI或LDAP的负载,也提高了对常用服务的访问效率。According to SOA architecture, the next generation software system will turn to the distributed, service-oriented and dynamically configured and deployed pattern. It is changing the Internet, augmenting the eyeball web with capabilities to produce transactional web. The web browser, which has been prevailing over the whole Intemet, lacks functionality, offline operation and API support, thus rich client is taken into account by some researchers and corporations. This paper proposes a kind of smart client architecture which may self- update and dynamically adapt to the re, mote service interface. The architecture proposed maitains a service connection pool at client side. To a certain extent, it may manage the frequently requested services＇ binding and accessing automatically so that the overhead of querying the UDDI or LDAP and balance of UDDI or LDAP may be reduced and the service acces_q efficiency can be improved relatively.
