在网站上运行Java小程序
[英]Running a Java applet on a website
问题描述
I have created a Java game using Eclipse. 
我已经使用Eclipse创建了Java游戏。 It has 11 classes (with one main class that calls everything else). 它有11个类（其中一个主类调用其他所有类）。 I called it as an applet in the following manner: 我通过以下方式将其称为小程序：
<!-- This is the applet handler to load the Handler Class to run the game -->
<td colspan="3"><applet code="Handler.class" codebase="History Adventure Alamo Adventure/" name="Alamo Battle Adventure" width="680" height="509" archive="Handler.jar" id="Alamo Battle Adventure">
</applet></td>
With it uploaded to the website, it shows an error and tells me to click for details. 将其上传到网站后，显示错误，并告诉我单击以获取详细信息。 When I select it, it tells me ClassNotFoundException: Handler.class 当我选择它时，它告诉我ClassNotFoundException：Handler.class
The code is in the body and I have nothing in the head. 代码在正文中，我头上什么也没有。 What have I done wrong? 我做错了什么？
Here is the rest of my code for the page. 这是该页面的其余代码。 The actual test page can be found at www.kluckhohndesign.com 实际的测试页面可以在www.kluckhohndesign.com上找到

This should get you further: 这应该使您更进一步：
<html>
<body>
<applet
code="Handler"
codebase="http://www.kluckhohndesign.com/History%20Adventure%20Alamo%20Adventure/"
name="Alamo Battle Adventure"
width="680"
height="509"
archive="Handler.jar"
id="Alamo Battle Adventure" >
</applet>
</body>
</html>
You can leave out the http://www.kluckhohndesign.com/ prefix on the codebase. 您可以在代码库上省略http://www.kluckhohndesign.com/前缀。
Now it causes an InvocationTargetException . 现在，它导致一个InvocationTargetException 。 But ask a new question about that. 但是，请问一个新的问题。
Further notes 进一步说明
- The
codeattribute should be the fully qualified name of the class & has nothing to do with the Jar.code属性应该是该类的完全限定名称，并且与Jar无关。 Most people think FQN equates toHandler.classbut it actually means justHandler.大多数人认为FQN等于Handler.class但实际上意味着Handler。 - The codebase can be simply
History%20Adventure%20Alamo%20Adventure/if it is coming off your site.如果代码库不在您的站点上，则它可以只是History%20Adventure%20Alamo%20Adventure/。 It needs the%20for spaces, as spaces are not valid in an URL.由于空格在URL中无效，因此需要%20的空格。 Then again, most deployers would not use directory names with spaces at all, for that very reason.同样，出于这个原因，大多数部署人员根本不会使用带有空格的目录名称。 - The
appletelement was never meant to be 'self closed' as was shown in your original page.如原始页面所示， applet元素绝不会“自我关闭”。 Instead it needs an explicit</applet>closing element.相反，它需要一个显式的</applet>关闭元素。 - Please keep testing in the simpler page I suggested, without all that other cruft. 请继续在我建议的较简单的页面中进行测试，不要再进行其他操作。
