JNI + Solaris : LD_LIBRARY_PATH / java.library.path initialisation
Hello.
Some JNI tools have been built to run on both windows and Solaris.
For the windows part, The PATH has been modified to add the DLL in order to be able to load the library into the JVM.
After some hard time to get the DLL build process doing his job, finally every thing worked.
But in Solaris, I can't have the library loaded (of course the library is build on Solaris ; a so file).
In a shell I try to launch some unit testing but every tries failed.
I tried to log the value of java.library.path and it remains empty on Solaris.
I think it's the environment variable that is not set properly. But I don't know what's wrong.
Here is the shell :
...
[ -z"$MOTEUR_HOME" ] && MOTEUR_HOME=`pwd`
# d閒inition du r閜ertoire des archives
LIBDIR="$MOTEUR_HOME/lib"
...
# classe ?lancer
_main=org.junit.runner.JUnitCore
# tests ?lancer
_tests=fr.mediapost.itineraire.moteur.MoteurImplTest
# le r閜ertoire contenant les moteurs
_libpath="$MOTEUR_HOME/moteur"
#classpath
_CP=$MOTEUR_HOME:$MOTEUR_HOME/configuration:$LIBDIR
if [ -d"$LIBDIR" ]; then
for i in"$LIBDIR"/*.jar; do
_CP="$_CP":"$i"
done
fi
...
#echo CLASSPATH : $_CP
echo JAVA_HOME : $JAVA_HOME
echo MOTEUR_HOME : $MOTEUR_HOME
echo Moteur : $_libpath
LD_LIBRARY_PATH=$_libpath
export LD_LIBRARY_PATH
# lancement
$JAVA_HOME/bin/java -DMOTEUR_HOME=$MOTEUR_HOME -Djava.library.path=$_libpath -DLD_LIBRARY_PATH=$_libpath -cp $_CP $_main $_tests
The output is :
MOTEUR_HOME : /export/home/users/sylvain.mougenot/moteur
Moteur : /export/home/users/sylvain.mougenot/moteur/moteur
JUnit version 4.1
09:57:12,361 DEBUG [MoteurImplTest] testCalculerInterface() - java.library.path=
...
Caused by: java.lang.UnsatisfiedLinkError: no libMoteur in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)
The libMoteur.so file is in the directory associated to the shell variable $_libpath.
Can someone tell me what I've to do to fix it?
Could the so file be found but Java can't load it?
