Can't get sockets to work

[Lincoln Spiteri <lincoln.spiteri@st.com>]

Hello,

I am trying to get the code below to work, it is  a simple server app which
echos any text it receives and then dies. The problem is that if compile this
and run it with the JDK all is ok. I telnet my machine on port 7070 type in
something and get 'Echo: something'  back.

If I try this with GCJ the server runs but when I telnet to it, it recieves my
input but the 'Echo: something' does not appear on the client side.

Am I doing something woefully wrong here or is there a problem with
ServerSocket or Socket. I tried looking at the file descriptor and socket code
during the weekend but did not have enough time to get really deep. Any help
would be appreciated.

Regards

Lincoln
