Re: [Java-player-users] Using latest Javaclient with Player 1.6.4

[Radu B. R. <ru...@cs...>]

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.
