[Java-player-users] Getting started

[Moshe S. <ms...@gm...>]

Hi guys,

I've worked with the Java Client before (version 1.5a) and I am trying
to re-utilize my project on the latest version.

Unfortunately, I fail to run even the simplest thing. The following
code hangs and never reach the println.

public static void main(String[] args) {
        PlayerClient pc  =3D new PlayerClient("localhost", 6665);
        PositionInterface pi =3D pc.requestInterfacePosition(0, 'a');      =
 =20
        System.out.println("EXIT");
}

The player server is up and running and everything works fine when I
access it by the c client.

Please advise.


p.s. I couldn't find any link to java-player from the site of
Player/Stage, but to the older version. Shouldn't the link be updated?

Thanks,

Moshe

Hellos,

I cannot explain the code hang. Try to run Javaclient in debugmode (by
using System.setProperty ("PlayerClient.debug") to true) and see if you get
any errors.

Are you running on a real robot or a simulated one?

The link to the new Javaclient web pages is posted in the P/S/G Contrib
section at http://playerstage.sourceforge.net/contrib.html. :)

Chers,
Radu.

Got nothing special from Stage.
The Java-Client print many lines:

Found it, but the link at
http://playerstage.sourceforge.net/clients/clients.html is outdated
and I couldn't find any back link from
http://java-player.sourceforge.net to
http://sourceforge.net/projects/java-player

Are you using the latest CVS Player or the original 1.6.4 release?

Thanks for this one, I will talk to Brian to modify
http://playerstage.sourceforge.net/clients/clients.html.

There is no direct link needed from http://java-player.sourceforge.net to
http://sourceforge.net/projects/java-player. You can click on download and
it will take you there.
