[Swarm-Support] JavaSwarm Eclipse Heatbugs issue

[Stephen Larson]

Hi,

  I'm having a problem that doesn't seem to have been reported yet using 
JavaSwarm under Eclipse and trying to run heatbugs.

  I am running Eclipse 3.1.2, with the latest version of javaSwarm, and 
Java 1.5.  I have set SWARMHOME to c:\Swarm-2.2-java and added appropriately 
to the PATH.  I have installed jheatbugs according to the instructions for 
running a swarm module in the document by S. Lytinen and S. Railsback.  I 
can run StartHeatbugs from Eclipse (no command line args) and get the basic 
GUI panels to come up.  But when I hit the "start" button, i get the 
following problem:

Exception drawSelfOn: Heatbug
Exception in thread "main" java.lang.NullPointerException
	at 
jheatbugs.HeatbugObserverSwarm.buildObjects(HeatbugObserverSwarm.java:231)
        at jheatbugs.StartHeatbugs.main(StartHeatbugs.java:30)
(Tcl -eval:) couldn't read file "C:Swarm-2.2-java/lib/tcl8.4//word.tcl": no 
such file or directory
   while executing
"source C:\Swarm-2.2-java/lib/tcl8.4//word.tcl"
while evaluating: source C:\Swarm-2.2-java/lib/tcl8.4//word.tcl

  I checked to make sure that my SWARMHOME was set correctly, and it is.  I 
tried permuting SWARMHOME to use a "/" or a "\\" instead but got the same 
error minus the verbage from Tcl.  It appears that somewhere inside 
JavaSwarm, the SWARMHOME is getting improperly parsed before it is passed to 
Tcl.  I'm guessing this might be a 1.4.2 to 1.5 incompatibility?  Haven't 
yet tried it using a 1.4.2 compiler.  Any advice before I start hacking 
around in the JavaSwarm/jheatbugs source?

Thanks,
