Since xml has many advantages over html , we also discuss the possible application of xml in labview and implementing strategy of using java applet to parse viml documents 武漢理工大學(xué)碩士學(xué)位論文本文進一步簡要分析和展望了xml在labview虛擬儀器系統(tǒng)的可能應(yīng)用,概述了html的缺點及xml的優(yōu)點和基本原理,提出以lava小應(yīng)用程序解析viml文件的技術(shù)路線。
We use session manager to solve the problem of sending and receiving the multi formats of media data ; use local service layer and java applet numeric underwrite mechanism to reading and writing the local resource 使用通信管理器功能模塊解決多種媒體格式的數(shù)據(jù)同時在網(wǎng)絡(luò)上傳輸?shù)膯栴};使用本地服務(wù)層或者javaapplet數(shù)字簽名機制,為applet存取本地資源提供有效手段。
Two kinds of web application architectures are included in section three . they are object web that uses java applet as corba clients and four layers architecture that uses javabean as corba clients 根據(jù)第二部分的分析,文章第三部分提出結(jié)合java和corba的兩種用于分布式應(yīng)用程序開發(fā)的www開發(fā)技術(shù):由applet作為corba客戶的對象web和jsp與corba結(jié)合的四層體系結(jié)構(gòu)。
Another increasingly common feature of some web frameworks is to create a richer and more responsive user interface by including dynamic client - side processing , through the use of code such as a javascript script or a java applet 另一個web架構(gòu)增長的需求特性是透過包含動態(tài)用戶端處理去建立一個更豐富、更具回應(yīng)能力的用戶界面,這可能會使用像javascript或是java applet的程式碼。
Using the groupware , collaborate members can interchange their ideas very well . the system uses a four layer design framework ( java applet client layer , communication manager layer , local service layer , application & rtp server with database server layer ) 實現(xiàn)時,軟件整體設(shè)計采用一種四層( javaapplet客戶層、通信管理器層、本地服務(wù)層、應(yīng)用服務(wù)器(含數(shù)據(jù)庫服務(wù)器)層)結(jié)構(gòu)設(shè)計方法。
Users may or may not understand why java web start can manage and launch a list of client java applications but is unable to have any connection to java applets that run with the java plug - in , despite the fact that either program can be launched from a web browser 用戶可能理解或還不理解為什么java web start能管理和啟動許多的客戶機java應(yīng)用程序,卻不能與以java插件運行的java applets建立任何連接,盡管事實是任一程序都可以從web瀏覽器啟動。
At last , when which choose java to realize webgis system , on one hand it makes use of the traditional method to realizes webgis in interiorly the network , on the other hand it employ the method of the usage java applet to realize it . namely it announces the internal geography information on the net 在選用java來實現(xiàn)webgis系統(tǒng)時:一方面,利用傳統(tǒng)的方法在內(nèi)部網(wǎng)絡(luò)實現(xiàn)webgis ,另一方面,使用javaapplet的方法來實現(xiàn)webgis ,把內(nèi)部的地理信息在網(wǎng)上發(fā)布。
After analyzing the advantage and disadvantage of some models ( such as cgi server apk plug - i activex java applet ) in constructing webgis , the paper analyzes the system characteristics and some application branches of a perfect net language - java , so all of this give prominence to the advantage of applying java in constructing webgis . then in view of software engineering the paper analyzes the superiority of developing component - based webgis by javabeans and practices the yunnan resort navigation system using maplnfo " s mapxtreme for java 3 . 1 beans . the system can provide some basal functions such as zoom in , zoom out , pan , adding theme , measuring and so on 接著論文分析了構(gòu)造webgis的幾種模式? ? cgi模式、服務(wù)器應(yīng)用程序接口方法、 plug - in模式、 activex模式以及javaapplet模式的優(yōu)缺點,進而闡述了網(wǎng)絡(luò)語言java的系統(tǒng)特性及其各種應(yīng)用分支,突出了采用java開發(fā)webgis的優(yōu)勢,然后從軟件工程的角度分析了采用javabeans進行webgis組件式開發(fā)的優(yōu)勢,并具體試驗了基于mapinfo公司mapxtremeforjava系列beans進行云南省旅游景點導(dǎo)航系統(tǒng)的構(gòu)造,開發(fā)出的系統(tǒng)實現(xiàn)了地圖顯示、放大、縮小、漫游、添加專題等常規(guī)的gis功能。
In order to realize dynamic data exchange and real - time communication , some methods to improve real - time capability of web - based remote monitoring and control system are analyzed and studied in this thesis . java applet technology , socket network communication technology and opc technology are discussed in detail . the web - based real - time remote monitoring and control technology is applied to the hydro power remote monitoring and control system in order to realize the automation reconstruction of hydro power , and the structure of hardware and software is described in detail 結(jié)合遠程監(jiān)控對通信的實時性要求,以實現(xiàn)網(wǎng)絡(luò)的實時數(shù)據(jù)交互為目標,在介紹socket網(wǎng)絡(luò)通信的基礎(chǔ)上,本文研究了基于web的網(wǎng)絡(luò)遠程實時監(jiān)控技術(shù),分析了服務(wù)器層作為遠程監(jiān)控系統(tǒng)中的中間層,與遠程監(jiān)控瀏覽器及現(xiàn)場監(jiān)控服務(wù)器進行實時數(shù)據(jù)通信的方法,對javaapplet技術(shù),以及opc技術(shù)作了詳細介紹。
