How to set java.library.path in Sun Java Web Server

think you can just set the LD_LIBRARY_PATH environemnt variable before starting it up

Possible to guide me on the commands to do it?

anyway i did a  and this is the print out:
/sun/webserver7/lib:/sun/webserver7/jdk/jre/lib/s
parc/server:/sun/webserver7/jdk/jre/lib/sparc:/sun/webserver7/jdk/jre/lib/sparc/native_threads:/sun/webserver7/https-bkpppv
ms/web-app/bkpppvms/ppvms/lib::/sun/webserver7/lib:/sun/webserver7/lib:/sun/webserver7/jdk/jre/lib/sparc/server:/sun/webser
ver7/jdk/jre/lib/sparc:/sun/webserver7/jdk/jre/lib/sparc/native_threads::/sun/webserver7/lib::/usr/lib

Basically, i have inserted a .dll file in/sun/webserver7/https-bkpppv
ms/web-app/bkpppvms/ppvms/lib (which is already shown in the print out for java.library.path) but yet i still get this exception:

the print out was retrieved using System.getProperty("java.library.path")
