Is it possible to use the latest version of Javaclient from CVS with
Player 1.6.4? It seems that I'd loose a lot of recent bug fixes by
going back to an old version of Javaclient, but I don't know if this
combination will cause me any problems.
Also, I've noticed that the HEAD revision in CVS generates several
"the field is never read locally" errors in Eclipse. A few of these
are actually bugs cause by a trivial oversight when copying and
pasting:

Hey Josh,
Yes, Javaclient from CVS should work nicely with 1.6.4 (although I
always test against 1.6.5 and latest 1.6.5 CVSed).
I am currently wrapping up the last classes for Javaclient2, and I think
that we should all concentrate our efforts of testing/developing and
using on the 2.x API.
I will have a beta version soon online. Any requests ? (I will integrate
Gareth's exception patches)
Btw, functions like the ones above (from AudioMixerInterface) will be
obsolete. Instead you will just get something like:
AudioMixerInterface ami = request...
ami.getLevels (); // request a PLAYER_AUDIOMIXER_GET_LEVELS
... // wait in a loop
if (isConfigReady ())
PlayerAudiomixerConfig pac = ami.getConfig ();
... and then access pac.getMaster_left, pac.getMaster_right,
pac.getPcm_left...etc
So basically all the Player structures will be accessible directly from
now on using get/set methods. I think this will ease things a lot.
Some feedback would be nice :)
Cheers,
Radu.

Radu, Thanks for the quick response. How soon is soon? I'm the teaching assistant for a class that is going to be using Javaclient, but I don't want to have to start with the current version and then switch everyone over. When you say 2.x API, are you still using Player 1.6.5, or the beta Player = 2.0?

Hey Josh, Yup, I'm talking about Player 2.0. I've been coding the 2.x interfaces for the last couple of days (I was about to start a thread here and on playerstage-users/developers *IF* we actually need a Java client anymore, provided that we can generate - to a certain extent - some basic functionality via SWIG), and it seems like the whole thing is getting close to release. How close it's hard to say... if it would be my call, we'd all work together to finish the damn thing until the end of the week, so we can all mind our AI/robotics high-level research afterwards. :) As about SWIG, don't get me started... I'm not the most prolific Java coder out there, but looking over some generated SWIG code (Yuck!) is what actually made me start porting Javaclient 1.6.5 to 2.0 anyway. :) Besides, what's the point of having a Java client, if you link against a system library, thus being unable to just copy a JAR nicely and use it on whatever operating system you want (JVM-enabled)? What interfaces would you need for your class? I can make sure that we finish working on those first. I will also send a mail to ps-developers and jump in to help them finish 2.0 sooner. I was too busy with other stuff until now to actually do something in that direction. You *could* also still use Player/Javaclient 1.6.5, which should still work nicely. Make a list of whatever interfaces you are going to use, hardware (drivers) and simulators, and we can look to see if they are bug-free. Cheers, Radu.

Radu, We're hesitant to switch to Player 2.0. This is for an undergraduate robotics class and we're already throwing enough at the students.=20 Adding an untested code base to the situation doesn't seem like a great idea. Specifically, we're the most worried about the documentation. Player 1.6.5 didn't have the greatest documentation, and I don't know how much further behind Player 2.0 and Javaclient 2.0 will be. I'm actually using SWIG at the moment to generate an interface for libgazebo. Going straight into libgazebo lets me run simulations much faster than real time. As a long term goal I want to create a higher level interface that can use libgazebo for faster than real time simulations, or player for controlling real robots.

Hey Josh, Yeah, I understand. It is a bit "risky". Well let me know if there's anything that you need for the Javaclient 1.6.5/Player 1.6.5 combo. Good luck with your class. Radu.

Btw, I just commited a patched AudioMixerInterface to the CVS. Forgot to
say thanks. :)
