Question

更新到Java version7 update 51后，我购买了代码签名证书并签署了我的applet。我有主applet（AppletDemo.jar）和另外两个applet（commons-codec-1.7.jar和FDxSDKPro.jar），它们由主applet使用。我用DigiCert证书签了全部。

所有这些都已签名，并使用jarsigner工具验证我收到此消息：

*s = signature was verified
m = entry is listed in manifest
k = at least one certificate was found in keystore
i = at least one certificate was found in identity scope
jar verified.*

当我尝试加载applet时，我在java调试控制台中收到以下消息（真正的url被替换为tag）：

basic: Plugin2ClassLoader.addURL parent called for <url>/fpApplet/AppletDemo.jar
basic: Plugin2ClassLoader.addURL parent called for <url>/fpApplet/FDxSDKPro.jar
basic: Plugin2ClassLoader.addURL parent called for <url>/fpApplet/commons-codec-1.7.jar

basic: Your security settings have blocked an untrusted application from running
basic: exception: Your security settings have blocked an untrusted application from running.
com.sun.deploy.security.BlockedException: Your security settings have blocked an untrusted application from running

我假设，Applet因此而被阻止，以及以下两行（Trust for：fpApplet / FDxSDKPro.jar已结束：Thu Jan 01 01:00:00 CET 1970）。

如果罐子签了，我不知道怎么会发生这种情况？有人有这样的问题吗？

默认情况下，版本7中的JAVA安全性很高，因此请将安全性从控制面板更改为中等。请按以下链接http://www.java.com/en/download/help/jcp_security.xml

Java Applet - 版本7更新51 - “Trust for：<url> fpApplet / FDxSDKPro.jar已结束：Thu Jan 01 01:00:00 CET 1970”</url>
