java - 如何离线运行此小程序？

标签 java debugging applet

我需要这个位于此处的小程序 link text (弹出窗口中的相同内容在这里:http://tcip.mste.illinois.edu/applet_popup.php?num=2)

我已经下载(实际上镜像了整个站点 :D )所有的 jars 和 js 文件。

其中一个 js (tcip.js) 描述了将调用哪个小程序以及从位于特定 jar 文件中的哪个类调用。

那么，我该如何离线执行/运行它呢？就像我必须将所有 jar 文件包含在 netbeans 项目中然后运行它一样吗？

因为我正在使用 Java，所以我需要这个小程序来进行我大学的电网演示。

我在页面源代码中得到的其中一行是这样的:

edu.uiuc.TCIP.education.summer06.lessons.lesson4.Lesson4Applet

这是什么意思……？是不是我下载的所有 5-6 个 jar 文件都同时运行..然后其中一个名为“lessons”或“lessons_old_naming”的 jar 文件具有这种结构

edu.uiuc.TCIP.education.summer06.lessons.lesson4.Lesson4Applet

因为这是包结构..？ Lesson4Applet 是我想要执行的..？

如何获取它以供离线查看/执行...？

将不胜感激..如果你们中的任何人能让它为我工作..用于离线(本地执行的 jar)查看。

最佳答案

深入研究启动该小程序的 JS 表明相关的小程序元素是:

<APPLET name='myApplet' WIDTH = 800 HEIGHT = 600 
        CODE='edu.uiuc.TCIP.education.summer06.lessons.lesson2.Lesson2Applet' 
        ARCHIVE='jfreechart-1.0.10.jar , jcommon-1.0.13.jar , jama-1.0.2.jar, lessons_old_naming.jar , psdataobjects.jar, psdisplayobjects.jar, anl_lpsolver.jar , zebLP.jar'>
</APPLET>

如果您使用该小程序元素和代码库 http://tcip.mste.illinois.edu/ 创建 HTML ，它应该工作。请注意，一旦小程序加载到我的 FF 中，我就会看到一个“黑屏”(耸肩)。

顺便说一句 - 您是否已获得小程序和网站制作者的许可，可以使用他们的小程序？

顺便说一句 - 我已经测试了这个 applet 元素并看到它在本地工作!

后来:现在我更仔细地看了你的问题，我意识到我从来没有真正正确地回答过它，因为我错过了“离线”的细节。我的错!

通过添加代码库属性，我通过允许 JRE 返回所有资源的原始站点来“作弊”。 AFAIU 这些资源是:

  1. archive 属性中提到的 Jars。
  2. 小程序使用的图像。

这会有点棘手。

让我们假设您希望 HTML 被(糟糕地)命名为 OFFLINE_applet.html，并且您希望所有内容都位于 powergrid 目录中。在那种情况下，结构将是..

  • 电网
    • OFFLINE_applet.html
    • jfreechart-1.0.10.jar
    • jcommon-1.0.13.jar
    • jama-1.0.2.jar
    • lessons_old_naming.jar
    • psdataobjects.jar
    • psdisplayobjects.jar
    • anl_lpsolver.jar
    • zebLP.jar
    • applet_images

实际上，并不是applet_images 中的每个图像都是必需的。这个小程序只使用了其中的大约 20 个 AFAIR，但是下载了所有这些并且应该可以工作。

当然，删除“代码库”属性，否则 JRE 仍将尝试返回到 http://tcip.mste.illinois.edu/资源网站!

测试一下然后回复我。
