Besides writing a common abstract api , the main effort is actually to implement the adapters to some of the already existing regexp engines in the java environment 除了编写公共抽象api ，主要的工作实际上是实现java环境中某些已存在的regexp引擎的适配器。
If you already have a supported java environment , download the server - only wasce setup file for your platform , then install community edition simply by running the wasce setup file 如果您已经有了支持的java环境，则只需要通过运行setup - wasce文件安装community edition 。
However , for the rest of the series , you will be expected to know the basics of grid technology and the java programming language including a suitable environment , such as that from 然而，对于本系列教程的其他部分来说，您需要了解网格技术和java编程语言的基本知识（包括合适环境的知识，例如sun所提供的java环境） 。
This means your code can run in a pure java environment when a small footprint and flexibility are key or integrate into an existing corba infrastructure with minimal code changes 这意味着，您的代码可以在纯java环境中运行（当小的资源占用量和灵活性很关键时） ，或者对代码作少量修改后集成到现有的corba基础架构中。
Of all the rexx interpreters i ve discussed in this article , this is the only one that does not meet the rexx language standardsso it is perhaps best described as " rexx - like . " its purpose is to bring rexxs ease of use to the java environment 在本文中讨论的所有rexx解释器当中，只有这种解释器不符合rexx语言标准所以称其为“类rexx ”最为恰当。这种解释器的作用是将rexx的易用性带入到java环境。
However , when people use java to realize their arcims application systems , they should make their systems built up directly on arcxml , a communicating language used in arcims , which complicates the process of gis system ' s implementation and forces developers to face the same problems traditional gis faced 不过，由于arcims各部件之间需要依靠arcxml语言进行通信，所以java环境下arcims应用系统的开发需要建立在对arcxml语法知识深入了解的基础上。这使开发者使用java开发gis功能时依然面临着与传统gis开发同样的问题， gis应用系统开发过程趋于复杂。
The forth and fifth chapter are the kernal part of this paper , in the first we present the data flowing model between data tier and logistic , get a meta model of it , and realization it , in the later we present you the data flowing model between view and logistic , get a meta model and realization it in java 第四部分和第五部分是本文的核心，其中第四部分是总结出数据层和逻辑层数据交互的模型，抽象出其元模型，并在java环境下实现该元模型。第五部分是总结表示层和逻辑层数据层交互的模型，并在模型的基础上提出元模型及在java下的实现。
Pose some models about mobile agent security by new technology of cryptology such as dsa , kerberos authorization service . 3 . based on java , put forward some secure communication encrpytion algorithm and functions between agents and hosts or agent servers , such as dsa , md5 , timestamp and so on 在java环境下，结合java支持代码可移动、异构平台等优势，实现对于移动agent安全诸方面较为常用的移动agent之间及与主机之间安全通信的消息摘要，数字签名和安全框架中的时间戳安全策略等功能。
Three tiers structure of sofeware which have been used in the sofeware system broadly , the first research objects , conclude the data flowing model between data tier and logistic and the data flowing model between view and logistic , then build the meta model of the two model , at last realizing the two meta model basing on using xml and software reusability , 作者通过对现在广泛应用的三层体系结构和n层体系结构的分析入手，提出数据层和逻辑之间交互的模型，逻辑层和表示层之间交互的模型，并在此模型的的基础上提出他们的元模型，利用xml技术，软件复用思想，在java环境下实现这两个元模型。
Firstly we introduced research background and theory foundation . data characteristics of half structure and xml and cscw are simply introduced ; very important critical technology of cooperation work : transform between xml and the relational database is researched deeply secondly . the emphatic questions such as principle and thought are expatiated , and a general transformation rule and realization such as the data abstract , integration and transform are put forward ; as well as we introduced data binding in java environment , and put forward a datachange model which works in cooperation work 本文首先介绍研究的背景和理论基础，对xml 、 cscw技术和web的半结构化数据特点做了简单介绍；接着对数据库协同工作中的关键技术： xml与关系数据库之间的相互转换进行了深入的研究，阐述了转换过程中的原理、思想精髓等重点问题，提出了通用的转换规则，以及在web数据库中数据的提取、集成、转换等实现技术；同时还介绍了在java环境下数据绑定的过程，并提出一个协同数据库管理系统的模型datachange 。
