RMI with jigsaw

Hi,

	I'm trying to enlarge jigsaw funktionality by making it possible to be 
administrated by using RMI. I have encountered some problems:
	
1. When I start my server class( which implements UnicastRemoteServer ) from
   httpd, simply by writing at the end of the main method:
   	MyAdministrator administrator = new MyAdministrator(this);
   ,Jigsaw changes its behaviour - I can't delete any directory using generic
   resource editor( I can still delete files ).

   Netscape get back an error: Document contains no data.
   
2. When I try to delete directory using RMI method deleteFolder, which use the   
   method delete(String child) from DirectoryResource, I get an exception 		

   java.lang.SecurityException
        at java.lang.SecurityManager.checkDelete(SecurityManager.java)
        at java.io.File.delete(File.java)
 	.....       
 	at java.lang.Thread.run(Thread.java)
 	
   In order to get appropriate DirectoryResource I wrote the which starts from   
   root resorce till the resource which I want to get
   ( maybe this is possible to get this resource by calling any jigsaw classes   
   method ?).
   
3. I delete file resources by calling also delete(String child) method from
   DirectoryResource and it deletes file resources but when I try to delete      
   phisical file from system file I get similar exception.
   
I will be grateful for any sugestion which could help me resolve that problems.

				Thanks
