In this paper , the rmi mechanism is adopted . in the communication all the distribution object is implemented with java , and with the help of java implicit security mechanism which includes secure apis , developer can add lower layer and higher layer security function Java的远程方法调用( rmi )允许程序员编写分布式应用程序,在这个分布式应用程序中,远程java对象的方法可以被运行于网络中不同主机上的java虚拟机( jvm )调用。
What was needed was a remote transport technology that combined the small footprint of java s rmi remote method invocation and the sturdiness of the more mature corba common object request broker architecture technology 所需要的就是一种远程传输技术,它兼有java的rmi ( remote method invocation ,远程方法调用)较少的资源占用量和更成熟的corba ( common object request broker architecture ,公共对象请求代理体系结构)技术的健壮性。
This paper discusses the construction of three - tier architecture applications using www technologies and component technologies respectively , and specifically for building three - tier architecture applications using corba component model , analyze the semantics of passing corba objects as the parameter of remote method invocations . a tool has been created to implement passing corba objects completely , including their state and behavior 本文分别讨论了使用基於www技术和构件技术来实现三层次架构,并特别针对使用corba构件模型来构建三层次架构,分析corba对象作为远程方法调用的参数的语义,并制作了工具实现完整传递corba对象的状态和行为。
Chapter 2 ananlyses the predominance of conbination of java and xml technologies in development of eai applications , and proposes a data exchange model based xml in eai application . chapter 3 discusses the integration of xml and database , especailly object - oriented database and relational database , and as example , introduces the realization of the transformation betewwn database and xml used xsu . chapter 4 discusses the communication between servers , focuses on xml - rpc and xml messaging , and then introduces simple object access protocal ( soap ) technology and its application in xml - prc and xml messaging 本文共分五章:第1章对eai的概念、内容及应用现状作了分析;第2章分析了java和xml构建eai应用的优势,提出了一个在eai中基于xml的数据交换模型;第3章介绍了数据库与xml的集成,着重是对象数据库和关系数据库,并以xsu为例介绍了其具体实现;第4章讨论了服务器到服务器之间的数据通信,主要是xml远程方法调用技术和xml消息传递模型,重点讨论了简单对象访问协议( soap )及其在xml远程方法调用和xml消息传递中的实现。
To reply the internet demand of style design , it draws two methods of remote data access : one is based on http , the data format is xml , the web server is constructed by jsp , the itc can obtain the data and parse it by msxml , so that it can reach the appropriate data access and format conversion . the other is based on soap and webservices , the webservices can provide remote procedure call to obtain the fashion parts information 面对款式设计的网络化要求,提出了两种实现远程数据获取的方法:基于http方式,采用xml作为远程数据交换的格式,利用jsp构建服务器,在客户端使用itc获取远程数据用msxml解析,达到远程数据的正确获取和格式转换;基于soap和webservices方式,利用webservices提供远程方法调用来获取款式部件信息,在客户端采用soaptoolkit获取数据后用msxml解析,达到远程数据获取的目的。
Many new features are implemented in dpcf runtime , such as : no any preprocessor and precompiler ; rmi - liked programming model ; objects created on remote hosts ; asynchronous remote method invocation ; migrating objects to heterogeneous hosts ; scalable support for multi - protocol of network Dpcf运行时的特性包括:不需要任何的预处理程序和预编译器;类似于rmi的编程风格;能在远程主机上创建对象;异步远程方法调用;能在异构主机间迁移对象;可扩展的多种网络通讯协议的支持。
As trobus , a middleware product compliant with corba v2 . 3 specification , is still based on the standard synchronous method invocation , it does n ' t work in some applications such as order / purchase system , real - time control system and information publishing system , etc . in this thesis , a service system was developed on trobus to provide communication decoupling and active services , which is compliant with corba event service specification Trobus系统是一个基于corba的分布式对象中间件产品,它兼容corba2 . 3规范。但由于它基于同步的标准远程方法调用,无法直接用于一些非耦合且异步的应用场合,如定购系统、实时监控系统和信息发布系统等。
