嗨，我写了一个包含APplet的web应用程序，我用这个标签在Html页面中启动APplet

<applet codebase="http://localhost:8084/WebForSpark" code="AppletBroadcaster.ZkusebniApplet" archive="AppletBroadcaster.jar, jave.jar " width="500" height="500"></applet>

所以很明显，我的build/web文件夹中的jave.jar是建立的

但是，当我在applet中按下从jave.jar执行某些操作的按钮时，javaconsole编写了以下代码

jave.jar应该做的一切都是正确的，但我的问题是，为什么在我的jave.jar中多次被称为lib/jave.jar呢

http://localhost:8084/WebForSpark/

并在小程序启动期间成功加载。。。对于no-call lib/jave.jar，我能做些什么？为什么会调用它？非常感谢

当前的applet元素归结为

<applet
    codebase="http://localhost:8084/WebForSpark"
    code="AppletBroadcaster.ZkusebniApplet"
    archive="AppletBroadcaster.jar, jave.jar"
    width="500"
    height="500">
</applet>

其中

/path/to/

可能是

/lib/

或其他路径。

谢谢您的回复，但我不完全理解您的意思。我的build/web文件夹中没有lib之类的文件夹或包。我没有明确告诉Java她应该搜索WebForSpark/lib/jave.jar，但我的jave.jar位于index.html旁边的web根目录（代码库）中。我的applet项目中只有使用lib文件夹的地方，但applets jar中却没有。我的英语不精确，所以请试着给我写下你所说的其他单词的意思。Url是由CODEBASE+Archvive组成的，所以在我的例子中是+jave.jar。请看我上面第9行的第一个javaconsole日志，这是JRE如何通信和下载jave.jar的。是的，我可以从浏览器访问JAVE.JAR，这对我来说是一个新的坏消息。。。我并没有意识到这一点，这确实是一个很大的安全问题，我必须将我的库放在另一个用户无法通过浏览器访问它们的地方。。。。但是在哪里…所以我做了一些实验。我尝试在myroot中创建文件夹库，并将JAR放入其中。将lib添加到codebase cause/WebForSpark/lib/lib/jave.jar中，因此我尝试将codebase设置回only/WebForSpark，现在它运行良好。但我真的不明白为什么。。。我的applet jar被复制到codebase，其他jar在lib文件夹中，两个jar都被成功加载。。在某些情况下，必须写入一个文件，JRE必须在codebase/lib文件夹中搜索JAR，但在何处搜索。再说一次，我可以在Lib文件夹trouhgt浏览器中访问jar，jar的安全位置在哪里？所以，如果我的小程序可以使用它们，这意味着所有互联网用户只能通过在浏览器中键入url来下载jar？我不能这样做，我的小程序可以加载外部JAR，但互联网用户没有？我只是在这里阅读你的答案，现在对我来说很清楚，谢谢，我明天会做一些实验。
