RE: trying to work out WinSwarm pretest-6's requirements

[Vidrine II,C. Kent]

I've had some success working with Swarm 2.2 pretest 6 in Windows 2000. I
run the model from the command line by using the script that is shown below.
It works just fine, but I always get an illegal memory reference message in
a popup window when I click the button to end the program.

set savepath=%path%
set JAVA_HOME=D:\java\j2sdk1.4.0
set JAVA_EXE=%JAVA_HOME%\bin\java.exe
set SWARM_DIR=D:\Swarm-2.2
set SWARMHOME=/Swarm-2.2
set CYGWIN_HOME=D:\cygwin
set cp=.;%SWARM_DIR%\share\swarm\swarm.jar;%SWARM_DIR%\share\swarm\kawa.jar
set path=.;%SWARM_DIR%\bin
set path=%path%;%JAVA_HOME%\bin
set path=%path%;%CYGWIN_HOME%\bin
%JAVA_EXE% -Xmx256m -cp %cp% my.package.name.StartSwarm --varyseed
set path=%savepath%

Subject: trying to work out WinSwarm pretest-6's requirements


Hi,
  sorry to post again about this but I thought I'd let people know about my
progress with getting Swarm 2.2 pretest-6 to work under Windows (2000)
independently of the provided scripts (i.e. javaswarm).
  I'd like to try and figure out what the bare minimum required to get Swarm
working in this way is. With Swarm-2.1.1 I was able to work from the FAQ's
advice (http://lark.cc.ukans.edu/~pauljohn/SwarmFaq/SwarmOnlineFaq.html#7.9)
but unfortunately that doesn't seem applicable to the latest snapshot
anymore.
  Bearing in mind that my IDE is not launched from the Cygwin shell and so
doesn't have access to the Cygwin environment variables, I've tried to
replicate the necessary ones through the Windows environment variables. All
that was required with Swarm-2.1.1 was:
1. appending C:\Swarm-2.1.1\bin to PATH
2. setting HOME to C:\.
3. setting SWARMDIR to C:\Swarm-2.1.1
4. I added the swarm.jar package to my IDE but not the kawa.jar package (the
JDK rt.jar is already included). This worked fine so I'm not sure when
kawa.jar is required.

  Now I've changed over the relevant environment variables and experimented
a bit here is what I've found:
1. removing C:\Swarm-2.1.1\bin from PATH results in a "javaswarm not in
java.library.path" exception in javaswarm.dll at runtime
2. with C:\Swarm-2.1.1\bin in PATH a runtime exception occurs in
javaswarm.dll "Can't find dependent libraries"
3. adding _JAVASWARM_LIBPATH as specified by running "eval javaswarm"
doesn't make any difference to the above exception
4. adding the kawa.jar package doesn't make any difference to the above
exception

  So, here are a few questions I'm trying to find the answers to:
1. what is kawa.jar used for/by?
2. what are the minimum packages needed to run a Java Swarm application?
3. what are the minimum paths that need to go in PATH?
4. what does _JAVASWARM_LIBPATH do?
5. where's the source for javaswarm.dll? My search hasn't found it in the
source for pretest-6.

  I think such minimum configuration information would be very useful in the
FAQ, as not all Windows users wan't to use Swarm through the provided
scripts.
        James
