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

Question

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)

Ignored exception: 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

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.
