问题

I'm trying to launch my java applet (version java 6) in server webpage but When I run it i have the next error:

    java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.security.pkcs11)

With eclipse, this Applet works fine but when I try it in the server don't work. I'm using an unsigned applet (.jar). Can be this, the ploblem??

In my java .policy file I added these lines and still not working

grant {
permission java.security.AllPermission;
permission java.security.AccessControlException;
permission java.lang.RuntimePermission;
permission java.lang.RuntimePermission "accessClassInPackage.sun.security.pkcs11";
};

the same error like with these original .policy file:

grant {
permission java.security.AllPermission;
};

Have anybody idea of the problem and the solution??

Thanks in advance

回答1:

You need to sign your applet, and latest java security baseline will block any applet signed with an untrusted certificate authority.

If you choose to self-sign the applet, you may need to lower your java security settings in order for your applet to execute.

回答2:

Oracle's recent Java distributions (since roughly last summer) has disabled access to anything in any package that starts with "sun.".

This can be overcome by using policytool to add:

permission java.lang.RuntimePermission accessClassInPackage.sun.

to your local java.policy file.

回答3:

add this to your java.policy file or use the policytool:

grant {
  permission java.lang.RuntimePermission accessClassInPackage.sun "com.acme.yourpackagename";
};
