SecureServer error

[shaziah aris]

I have installed JSSE and following the instructions as carefully as I could. But when i compiled the SecureServer.java it generates the following error:
1. Cannot resolve symbol HTTPServer
symbol: class HTTPServer
location: class SecureServer
public class SecureServer extends HTTPServer
^
2. Cannot resolve symbol
symbol: method run()
location: class SecureServer
server.run
^
3. Cannot resolve symbol
symbol: variable ServerPort
location: class SecureServer
(SSLServerSocket) ssf.createServerSocket(ServerPort).
^
Hope to get some early responses.
TQ.
