Thank you for the advice: it does work with JDK ... at least, it
displays the small window I had in the file...
However, I notice that there are (not so) subtle differences between
JDK and Kaffe:

1) unless I use:  "jdkswarm StartCooperation |tee" to run the program,
I do not see any written output in the Swarm terminal (I found the
answer in the archives for this list, but why is it so?)

2) With Kaffe, I could compare a String variable with a string using
the == operator:

String variable="first";
variable=="first"; // return true

With JDK, the same bit of code returns false. Is there another way
than == to compare strings?

There may be more, but 2) is enough to prevent the simulation
written for Kaffe to work.

Help!

Marie-Edith.
