[Swarm-Support] A Question (jSWARM Tutorial)

[Paul Johnson]

Dear Sagib:

I'm transferring this message onto the address@hidden list.

Can you compile and run other Swarm programs?  For example, jheatbugs or 
jmousetrap?  If you can run them, then we know the problem is in the 
program you are trying to run.

Now, here is the big issue. THere is no finished "java tutorial" aside 
from Marcus Daniel's online slides and program called SDG.  There is a 
half-way finished project to make a java version of the bugs tutorial 
that was started by Charles Staelin (when Charles sent that to me, I 
named it "CharlesJavaTutorial.zip" and that is the name under which I 
distribute it).  As far as I know, that was never finished. That 
tutorial has been put into the Savannah web page/CVS archive and various 
volunteers have appeared on the scene to do this and that, but it is not 
done.  So I'd suggest you try to get the newest version--whatever state 
it is in--and then see if you can make that run. If you can't, then fix 
it ( :) and check the fixes back in on Savannah.

I'm browsing in Savannah and I can find the files in the CVS:

http://savannah.nongnu.org/cgi-bin/viewcvs/swarm/apps/java/jtutorial/

Instructions on anonymous CVS check out are at:

http://savannah.gnu.org/cvs/?group=swarm

So, you can check out the code and fix it up. You will have to register 
as a developer in order to check in your fixes, though.

But I do not see a java tutorial listed as an active project. I'm pretty 
sure that was an oversight.

There was another java tutorial,  by Anthony Liekens, (who runs the 
alife.org site). I don't know what state that is in.


If you don't want to do that, then I'd suggest you learn about java 
Swarm by studying the SDG  example and other programs that we (SDG 
members) are building.
