Question

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：hxxp：//tcip.mste.illinois.edu/applet_popup.php？num = 2）

（请将“hxxp”替换为“http”以访问上述链接）

我已下载（实际上镜像了整个网站：D）所有的罐子和放大器js文件。

其中一个js（tcip.js）描述了将调用哪个applet＆amp;哪个类位于特定的jar文件中。

那么，我如何离线执行/运行它？是这样的，我必须在netbeans项目中包含所有jar文件＆amp;然后运行它？

因为我是java＆amp; amp;的初学者我在学院的电网演示中非常需要这个applet

如果有人能帮我解决这个问题，我将非常感激。

我能够在页面源中获得的一条线是：

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

这是什么意思？是否像我下载的所有5-6个jar文件同时运行..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..？和Lesson4Applet是我想要执行的...？

如何才能让它离线查看/执行..？

非常感谢..如果你们中的任何人能够让它为我工作......对于离线（本地执行的jar）观看。

Answer 1

深入研究启动该applet的JS建议相关的applet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applet元素和代码库http://tcip.mste.illinois.edu/创建HTML，它应该可以正常工作。请注意，一旦applet加载到我的FF中，我只得到一个“黑屏”（耸耸肩）。

BTW - 你是否获得了applet和网站制作者的许可才能使用他们的applet？

顺便说一句 - 我已经测试了这个applet元素并且看到它在本地工作了！

后来：现在我更仔细地看你的问题，我意识到我从来没有真正回答过它，因为我错过了'离线'细节。我的坏！

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“欺骗”。 AFAIU这些资源是：

存档属性中提到的Jars。
小程序使用的图像。

这会有点棘手。

让我们假设您希望HTML（不良）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......

能量栅格
- OFFLINE_applet.html
- jfreechart的-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
  - 在http://tcip.mste.illinois.edu/applet_images/

实际上，并非所有applet_images中的图像都是必需的。这个小程序只使用了大约20个AFAIR，但是下载它们并且应该可以正常工作。

当然，请删除“codebase”属性，否则JRE仍会尝试返回http://tcip.mste.illinois.edu/网站获取资源！

测试并回复我。

Answer 2

将php页面的结果保存为html页面并在任何浏览器中打开它。 applet不需要服务器连接，然后它就可以工作。

如何离线运行此Applet？
