By default, the JVM sets the java.library.path system property, which is uses to locate shared objects, to the LD_LIBRARY_PATH. So as long as the LD_LIBRARY_PATH references the directory containing the .so file, you should be set. If you install JBoss Native, check the run.sh script because at one time it set java.library.path to $JBOSS_HOME/bin/native. If that is still the case, you need to set java.library.path to $LD_LIBRARY_PATH:$JBOSS_HOME/bin/native. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4145569#...
