Problems running Swarm in Forte 3.0 for Windows

[Steve Kembel]

Greetings all,

I'm writing to see if I can resolve a problem getting Swarm to run outside
of the Cygwin terminal - I would prefer to use the Forte for Java 3.0 IDE to
develop and run Swarm code under Windows 98SE. It seems that others have
been able to do this, but the methods they used to get it up and running
aren't working for me.

I initially installed the Swarm 2.1.1 binaries on a Windows system with
JDK-1.3.1_02 installed. I am able to run Java Swarm programs in the Swarm
terminal, but when I set up jheatbugs to run under Forte by adding swarm.jar
to the classpath, I get some errors. The program will compile and run, but
as soon as I click "Start" on the Swarm window, the execution halts as the
raster window comes up (it never appears, just a blip on the screen and then
the program crashes hard):

JAVA caused an invalid page fault in

I looked through the archives and it seems someone was having a similar
problem that went away after they applied the updated 2.1.1 DLL's.
Unfortunately these DLL's are no longer available on the Swarm FTP site (at
least I couldn't find them), so I tried to get it running using
Swarm2.2-pretest4 (Are the 2.1.1 updated DLL's available anywhere?). Now I
am getting a different error. I've applied all the updated DLLs and JARs and
such from the /w32/latest/ directory on the FTP server, have installed
Cygwin with the tcl/tk 8.0 libraries, but still get the following error
message every time. Is there a way to force javaswarm.dll to tell me which
libraries it is missing? I've made sure that c:\swarm-2.2\bin and
c:\cygwin\bin are in my PATH:

Exception caught: C:\Swarm-2.2\bin\javaswarm.dll: One of the library files
needed to run this application cannot be found
java.lang.UnsatisfiedLinkError: createBegin
        at swarm.SwarmEnvironmentCImpl.createBegin(Native Method)
        at swarm.Globals.<clinit>(Globals.java:25)
        at StartHeatbugs.main(StartHeatbugs.java:15)
Exception in thread "main"

Thanks very much if you have any insight into this problem.

Regards,
Steve
