我制作了一个 Java Swing GUI 并试图将其放到网站上，我将我的 html 文件放在 lwjgl_jar 文件夹中并解决了 my previous problem关于无法找到 AppletLoader 但我现在收到一个新错误:
Permissions for Applet Refused. Please accept the permissions dialogue to allow the applet to continue the loading process.
错误出现在告诉Java“这次运行”之后。所以我在网上搜索并发现我的问题的解决方案是我的 jar 文件尚未签名，考虑到我正在使用我认为应该已经签名的 Slick 和 lwjgl 文件，但我的 racegame.jar 包含我的，这很奇怪小程序可能需要签名，所以关注了this guide to signing jars :
然后进入最后一步并输入:jarsigner -keystore myKeystore racegame.jar myself
签署我的 racegame.jar 但它说:
jarsigner: unable to open jar file: racegame.jar
我尝试使用的任何其他 jar 文件也会出现此错误。
为什么不打开 jar 文件并对其进行签名？完全按照指南中显示的方式执行并测试了所有其他步骤。

我曾经在网上找到这篇关于 How to sign the JAR Files 的文章，这篇文章可能包含一些内容，可以在某种程度上帮助你。请看一看:
Sign All Applet JAR files
Applets are back! And now applets can do more than ever before thanks to
signed JAR files. By signing your JARs, you can get access to the filesystem
and other resources that were previously off-limits, provided the user
grants your applet those privileges. And signing JAR files is now very easy
thanks to tools bundled with the JDK. However, be certain to sign all JAR files
used by your Java applet. If you sign the JAR file with your main applet class,
your applet will launch. If it later uses classes from another JAR file, though,
you can run into trouble. If the newly-loaded class tries a restricted operation
and its JAR file isn't signed, your applet will fail at that point with a
security exception. Rather than waiting for this and debugging it when it occurs,
save yourself the trouble and sign all of your JAR files up front.
You can create your own certificate using tools provided by the JDK.
keytool -genkey -alias mykey lets you create your own certificate. Be sure to
specify an expiration date far in the future with -validity 1000. The default is
only 6 months.
Sign your JAR files with jarsigner my.jar mykey (where my.jar is the name of
the jar file to sign).
Deploy all of your JAR files to a folder on your web server, add an HTML page
with the applet tag, and let the world enjoy your new applet with powerful
permissions.
keytool -genkey -v -key store mycompany.keystore -alias myalias_goes_here -keyalg RSA -keysize 2048 -validity 10000
