Entries in .java.policy ignored

Question

I'm developing a JAVA Applet that requires read and write access to a folder. When I add the following entry into the java.policy file within the JRE folder it works:

 permission java.io.FilePermission "${user.home}${/}logtest${/}-", "read, write";

However if I add the entry in the .java.policy file within the users home directory it does not work.

Investigating further I add another policy file mytest.policy containing the exact same permission above and modified java.security file with:

policy.url.1=file:${java.home}/lib/security/java.policy
policy.url.2=file:${user.home}/.java.policy
policy.url.3=file:${user.home}/mytest.policy

The permissions are successfully applied.

Does anyone know why .java.policy permission entries don't work?

尝试编辑文件C：\\ Users \\ USERNAME \\ AppData \\ LocalLow \\ Sun \\ Java \\ Deployment \\ deployment.properties并添加到文件的下一行：deployment.security.use.user.home.java.policy = true
