unsatisfied link error

[ketandba]

hi,
i am developing web application using java.
i am using ant builder for build the java project.
i am creating .ear file through ant build.xml and deploy this .ear file on jboss application server.
for running some java program i have to use shared library...so at run time i have to pass
java.library.path = path/of/shared/lib/libdb_java-4.3.so
this libdb_java-4.3.so is shared library and it resides on linux server where jboss is installed.

when end-user running this application through browser(from windows operating system), how pass the
java -Djava.library.path for getting shared library...

otherwise program terminated with
Exception in thread "main" java.lang.UnsatisfiedLinkError: no db_java-4.3 in java.library.path

while generating .ear file through ant builder..
i am just compile the classs which includes .jar file in classpath.

if i run the program on linux server by giving command
java -Djava.library.path=path/of/shared lib/libdb_java-4.3.so programName.class it works
perfectly.....
Is any setting on jboss server..or where to put shared library on jboss directory structure...
pl. guide me...
Thanks in advanced..

i think i have to change the run.sh of jboss server.
but how?

here is my run.sh for your ready reference..
