Hi,
As far as i know dll can't be called inside a java code directly.
But u can call them using java native interface(JNI)
(write a c program to call the dll and use JNI for calling the program).
A bit of google search will show lots of examples available in the net.

Basically you write a C wrapper around the DLL using a header file that javah will generate for you. Try this google search for more JNI info:

Warning, JNI is pretty advanced and does break the platform independance. You may want to make sure that there is no other way to do what you are trying to do.
Hope this helps.
