Question

当我想在服务器上加载Applet时，浏览器会显示：

java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: http://<my server>:9080/ram7.5.2.1/applets/lifecycle.jar
    at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source)

    at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:795)
Ignored exception: java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: http://<my server>:9080/ram7.5.2.1/applets/lifecycle.jar

但问题是我已将该属性放在清单文件中，如下所示：

Manifest-Version: 1.0
Created-By: 1.6.0 
Permissions: all-permissions
Application-Library-Allowable-Codebase: *
Application-Name: SearchApplet
Caller-Allowable-Codebase: *

我不想更改Java安全级别或将网站放入异常站点列表。

问题解决了。它应该首先将标签添加到清单文件中，但也应该将标签添加到html标签。
