php - SecureCookiePermission 问题 - Applet 无法与最新的 Java 6 更新 29 配合使用

Question

在我们的网站中，我们使用的小程序在升级到 Java 6 Update 29 后无法正常工作。小程序应该与服务器通信以将数据存储到数据库。 Applet 在较低版本的 Java(更新 22、26 或 27)中运行良好，并且不可能要求我们的客户降级 Java 版本。我在 Java 控制台中发现了一些错误，我认为 java 无法访问/创建 cookie 或 session (某种权限问题)。谁能帮我解决这个问题吗？

谢谢!

Answer 1

嗯...我不太确定，但这条线是

java.security.AccessControlException: access denied (com.sun.deploy.security.SecureCookiePermission origin.http://www.example.com:80)

可能表示该小程序正在尝试以“cookie”形式访问其源，或者某些 cookie 策略设置错误的内容，或者您​​的小程序未签名。

...因为cookies tut note说的是

You must sign your RIA JAR file in order to access cookies. See the documentation for the jarsigner tool to learn how to sign JAR files.
