Use Java Native Access (JNA) : http://jna.java.net/

System.LoadLibrary can be used to load the libraries. Check this previous thread for example usage

You need to use JNI to call native functions. In your case it you need to load Library first in memory using Runtime.getRuntime().loadLibrary(PATH_OF_DLL_FILE)

you can use following link too http://www.equestionanswers.com/dll/java-call-dll-functions.php
