DistributedCache.addResource though not sure if adding just text files

Subject: External jar dependency of map reduce jobs
I have few map reduce jobs that I am invoking from a glasfish container.
I am not using "hadoop" command line tool but calling the jobs directly
from glassfish programatically. I have a driver that runs on glassfish
and calls these jobs sequentially. I was able to run the jobs as long as
they do not depend on external jar files. But I have one job that
depends on external jars and that fails with ClassNotFound exception.
I know that -libjars options can be used when using command line hadoop
but since I am invoking the jobs programatically from an app server, I
am wondering how I can add external dependencies in this case.
Any help would be appreciated.
