Hello Miyuru. I am unable to reproduce the problem you are having. On my system (RedHat 6.3), your EchoServer works ok both when I set X10_NPLACES and when I don't. Am I doing something differently?
$ vi EchoServer.x10 // paste your program below
$ ../bin/x10c EchoServer.x10 // compile with X10 2.3.1
$ ../bin/x10 EchoServer // run without X10_NPLACES
$ telnet localhost 1212 // in another window
> Trying ::1...
> Connected to localhost.
> Escape character is '^]'.
> hi
> hi
> there
> there
// kill EchoServer
$ X10_NPLACES=2 ../bin/x10 EchoServer // run with X10_NPLACES=2
$ telnet localhost 1212 // in another window
> Trying ::1...
> Connected to localhost.
> Escape character is '^]'.
> hi
> hi
> there
> there
// kill EchoServer

Subject: [X10-users] An Echo Server in X10
Hello,
I am trying to write a very simple Echo server using managed X10. The code
I wrote is shown below. The code compiles and runs well with X10 2.3.1
unless I set the variable X10_NPLACES. Once I set the variable X10_NPLACES
the application continues running. However, I cannot connect to the server
from outside (E.g., via telnetting to port 1212). Could any one please
explain me the reason for such behavior and a solution that I can take? I
want to run the echo server with multiple places. I tried to code the
server in Java and link to X10 via @Native() syntax but faced the same
problem. Thank you very much for your support in advance.
Thanks,
Miyuru.
