[9fans] Styx/9p implementations in JavaME

[Anthony Sorace]

I'm beginning a project that involves writing some Styx servers in
Java, particularly in a JavaME (formerly known as J2ME) environment.
Uriel's nice page on 9p implementations lists two Java
implementations, but neither's been updated in a good while, one is
client-only, and neither lists which flavor of Java it's designed for
(write once run somewhere?). Does anyone have any information on a
Styx server in a current-ish Java?

I thought J2ME was limited to http connectivity...  At least my
initial experiments with it on my motorola razr had me limited to http
connectivity via limits in the classes available I thought.

I didn't spend a lot of time with it though.

I don't *think* that's right. I'm very, very far from a Java expert,
but my impression from more knowledgeable people is that JavaME allows
direct socket communication, but the implementations on many devices
do not. Certainly that was our experience when we were working on
applications which tried to listen on the network: JavaME provided the
capabilities, but almost all of the handsets we looked at did not.

I'll keep you posted.

It might just depend on what profiles are implemented.

Ah here we go from Beginning J2ME (Li and Knudsen) p159

"Although the MIDP 2.0 specification requiers only HTTP and HTTPS
connections, it suggests that implementations support socket, server
socket, and secure socket connections."

but of course!  it's a telephone environment.
it must have profiles to say just how things can be incompatible.

I have ssh, telnet irc, everything in my sony w300i (MIDP 2.0)

here a tutorial implementing telnet:

ah, good. it's by the guy who'd put me under the impression that it
was possible. ;-)

Unfortunately it didn't seem the edition of motorola razr I had from
Cingular was capable of anything but http connections... so I wrote a
gateway to some apps on my server at home and used xinetd with a
header to implement just enough of http to make the phone think I was
a web server.

Nowadays, I'd have written my application with Yaws (erlang web
server) and had it generate dyanimc content, but at the time the app
was in C++.
