Problems trying to retro fit SSL to server
Hi all, im trying put SSL sockets into my server, but am encountering a few problems, mainly with the following two lines
SSLSocket sslsocket = (SSLSocket) sslserversocket.accept();
in my Accept function (null pointer exception - trying to cast a Socket to an SSLSocket?)
and
//sslserversocket = new SSLServerSocket( port );
in my Listen function
Apologies for the full code listing and the fact that it is littered with older element of the server, but they may be the sources of the problem :-)
Thanks in advance
