我正在尝试引用 JLayer。

<applet
code="AppStart.class"
height="480"
width="640"
archive="jl1.0.jar, AnApplet.jar"
</applet>

我不断在控制台上收到此错误

Exception in thread "pool-1-thread-1" java.security.AccessControlException:

有什么帮助吗？

这是我第一次使用引用的 jar。我的其他小程序工作正常。

引用的 jar 未签名，它正在尝试创建一个线程，这在 applet 中的未签名 jar 中是不允许的。

签字。
