[Gvsig_english] gvSIG and Java on Mac OS X

[Benjamin Ducke]

Dear developers/list,

I am currently trying to understand how Java works on Mac OS X.
Since Apple decides what Java gets installed on any version of
Mac OS X, not the user, I would like to be able and bundle my own
1.6 JRE with gvSIG, so that I can deploy an identical version on
any Mac.

As a JRE, I am using the Soylatte FreeBSD port and that seems to run
fine, but gvSIG always picks up the system's outdated Java 1.5 (I am
running on Mac OS 10.4 with no intentions whatsoever to update
to 10.5).

Now, I have tried to recreate the whole Java startup procedure using
a shell script, which I modeled after the one for Linux:

----

#!/bin/sh
# gvSIG.sh: startup script for gvSIG on Mac OS X
PATH_TO_GVSIG="/Users/bartsimpson/Desktop/gvSIG1.1.2.app"
PATH_TO_RES="$PATH_TO_GVSIG/Contents/Resources/gvSIG/gvSIG 1.1.2 build 
1045.app/Contents/Resources"

export DYLD_LIBRARY_PATH="$PATH_TO_RES/NativeLibs"
export PROJ_LIB="$PATH_TO_RES/Java/gvSIG/extensiones/org.gvsig.crs/data"

cd "$PATH_TO_RES/Java"

# Setup Java environment and run gvSIG

# Java tuning settings
MAX_HEAP=512
INI_HEAP=512

JAVA_VM="/Users/bartsimpson/Desktop/soylatte16-i386-1.0.3/bin/java"

$JAVA_VM -Djava.library.path="../NativeLibs" -cp 
andami.jar:./lib/gvsig-i18n.jar:./lib/beans.jar:./lib/log4j-1.2.8.jar:./lib/iver-utiles.jar:./lib/castor-0.9.5.3-xml.jar:./lib/crimson.jar:./lib/xerces_2_5_0.jar:./lib/javaws.jar:./lib/xml-apis.jar:./lib/looks-2.0.2.jar:./lib/JWizardComponent.jar:./lib/kxml2.jar:./lib/jcalendar.jar:./lib/jh.jar 
-Xms${INI_HEAP}M -Xmx${MAX_HEAP}M com.iver.andami.Launcher gvSIG 
gvSIG/extensiones "$@"

----

This goes almost all the way to starting gvSIG, but eventually fails:

Can someone on this list make sense of that error message?
Is the problem with the CRS library? Did I forget to include
something into the Java classpath or the system's linker path?

Thanks,

Ben
