我如何离线运行此Applet？

问题描述 投票：3回答：2

我需要此小程序位于link text（在弹出窗口中也相同：http://tcip.mste.illinois.edu/applet_popup.php?num=2）

我已经下载（实际上是整个站点的镜像：D）所有的jar和js文件。

其中一个js（tcip.js）描述了哪个小程序将被调用＆并从特定jar文件中的哪个类中调用。

所以，我如何离线执行/运行它？是否必须在netbeans项目中包含所有jar文件然后运行它？

正如使用Java一样，在我的大学中，我需要这个小程序来进行Power Grid演示。

我能够在页面的源代码中找到的几行是：

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

这是什么意思..？就像我下载的所有5-6个jar文件都同时运行..然后一个名为“ lessons”或“ lessons_old_naming”的jar文件具有此结构]

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

因为这是包装结构。和Lesson4Applet是我要执行的。.]

如何获取以供离线查看/执行。。

非常感谢。如果您的任何人都可以为我工作，以便进行脱机（本地执行的jar）查看。

深入研究启动该小程序的JS，表明相关的小程序元素为：

<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>

如果使用该applet元素和http://tcip.mste.illinois.edu/的代码库创建HTML，它应该可以工作。请注意，一旦将小程序加载到我的FF中，我只会得到一个“黑屏”（耸耸肩）。

顺便说一句-您是否获得小程序制造商和网站的许可使用他们的小程序？

顺便说一句-我已经测试了这个applet元素，并看到它在本地可以工作！

[稍后：现在我更加仔细地研究您的问题，我意识到我从来没有真正正确地回答过这个问题，因为我错过了'离线'的细节。我的坏人！

通过添加codebase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. 存档属性中提到的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（粗略地）命名为OFFLINE_applet.html，并且您希望所有内容都位于powergrid目录中。在这种情况下，结构将是..

  • powergrid
    • 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，不需要applet_images中的每个图像。此小程序仅使用其中的20个，但是请下载所有小程序，并且应该可以使用。

当然，删除'codebase'属性，否则JRE仍将尝试返回http://tcip.mste.illinois.edu/站点获取资源！

测试并回到我身边。

将php页面的结果另存为html页面，然后在任何浏览器中将其打开。如果该applet不需要服务器连接，它将可以正常工作。
