PCGU1000 Software in Java

Hi there,
i would like to write a Software in Java(Eclipse) to control the PCGU1000.
I have already downloaded the sample “pcgu1000_sdk_rev5”, there is the FGULINK.dll inside. The samples are only for Delphi or C#.

Now, i have to call the FGULINK.dll in Java for communication to the PCGU1000.

Does anybody have a sample program in Java, or know how to communicate between FGULINK.dll to Java(Eclipse)?
