Maybe I am not clear about your question, but a ServerSocket just sets up a Socket as an end-to-end connection with another host's socket, by implementing its .accept() method.

That is an error message from your Operating System saying that you don't have the telnet program installed.
There is a chance, also, that it is not that, but that you have a messed up reference to telnet in your environment variables, and so the OS can't find it. You might want to check that.
It would be pretty unusual that your OS hadn't bundled telnet.
(If you run Windows, you can search your hard disk like this :) dir C:\telnet.* /s

i checked it is windows 7 enterprise operating system.

Yes, but did you run that little command I posted above, to see if telnet is resident?
@krakatoa,
@gudii9,
Did you attempt to install Telnet using the instructions provided in the link above?
It would be pretty unusual that your OS hadn't bundled telnet.If you have a look at the link that I posted above, the very first (informative) line on the page states:
Telnet Client is not installed by default on Windows 7, Windows Server 2008 R2, Windows Vista, or Windows Server 2008.And note that I didn't say that it ISN'T included (bundled) with Windows, it's just that it isn't installed by default.

If you have a look at the link that I posted above, the very first (informative) line on the page states:
I don't always have time to read links.
I'll remember not to "overinform" people next time.

C:\Users\xyz001>C:\telnet. * /s
The system cannot find the path specified.
I got above message. I will try to install by following above link once I reach home from home laptop.

OK, so when it finishes the search, if it says :
"File not Found"
then you do not have telnet installed.
"File not Found"
then you do not have telnet installed.

The server asks us our name, so I typed 'Bob'. It says 'Hello, Bob' and then closes the connection.
