socket creation

[hilz]

hi
i am trying to create a socket as follows:

mailSocket = new Socket("localhost",8084); //tried with a lot of other port
numbers too

and i keep getting the exception:

java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:171)
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:158)
at java.net.Socket.connect(Socket.java:452)
at java.net.Socket.connect(Socket.java:402)
at java.net.Socket.<init>(Socket.java:309)
at java.net.Socket.<init>(Socket.java:124)
at mail.Server.<init>(Server.java:28)
at mail.Server.main(Server.java:11)



what do i need to do to be able to successfully create a socket?
thanks
hilz

you need the port to be open (i.e. a ServerSocket accepting connections on
that port) ....

The Socket constructor actually connects to the remote host and port
you specify. If nobody's listening, the constructor will fail as
you've discovered.

Either connect to a well known service (for example port 80 on most
web servers), or write a second program that opens a ServerSocket to
accept incoming connections on a port you've chosen.
