Help with signing jar files

Question

hi,
Iam trying to let a applet do file acces on a client. Therefore I must sign a applet so it may access the filesystem. This works, but the code keeps screaming about security violations.
Now ive vopied the code from a example from Oracle and I found one difference.
next to the fileUploader class that I also have in my jar file there is a
FileUploader$1.class with the following code:
import oracle.ewt.thread.Task;
import oracle.ewt.thread.TaskEvent;
final synchronized class FileUploader$1 implements Task
    private final FileUploader this$0 = fileUploader;
    private final boolean val$nf = flag;
    private final Object val$val = object;
    public void runTask(TaskEvent taskEvent)
        FileUploader.access$0(this$0, val$val, val$nf);
    FileUploader$1(boolean flag, FileUploader fileUploader, Object object)
}but if I try to compile this code then I get all sorts of error telling me Iam missing vars and methods.
Can anyone tell me why this class is there and what it does and if its nessesary for the fileaccess then how can I create it

a Name1$Name2.class file is generated from an inner class Name2 in a class Name1.
in your case you want to look at and compile FileUploader.java. This will then generate any inner class FileUploader$innerclass.class files necessary
