I need my source code to recognize a dll while running my SAR in JBoss.

The structure of my SAR is as follows:

-MySar.sar
-META-INF
-jboss-service.xml

-service
-MyMBeanClass.class

-commons-io-1.2.jar

-commons-logging-1.1.jar


So where can I put my dll and how can I get my bean to read it? Thanks.
