I am a newbie at JNA and need some assistance. First let me explain what I am trying to do:

I have an unmanaged DLL (I do not have the source code). I would like to create a Java wrapper around this DLL. After several days of intense frustration I have given up on implementing the wrapper using JNI, due to an exception that I cannot resolve. I have thus turned to JNA.

The problem is, I cannot get my JNA code to compile. I am sure that I must be missing something simple. I have include my code below as well as the build error.

Java Code

------------------------------------------------------- Rda2Server.java

--- package rda2;

import com.sun.jna.*;

public interface Rda2Server extends Library { Rda2Server INSTANCE = (Rda2Server)Native.loadLibrary("RDA2", Rda2Server.class);

public void Connect(String DataPath, long Workstation, String Username, String Password); public void Disconnect(); public boolean Connected(); }

rda2.java

--- package rda2;

import com.sun.jna.*;

public class rda2 { public static void main(String[] args) { boolean connected = false; Rda2Server serverLib = Rda2Server.INSTANCE; serverLib.Connect("C:\\database", 7, "", ""); connected = serverLib.Connected();

if (connected) { serverLib.Disconnect(); connected = serverLib.Connected(); } } }

Compilation Error

--------------------------------------------------- C:\j2sdk1.4.2_14\bin>javac D:\WS\DSDProjects\Utility\rda2\rda2.java D:\WS\DSDProjects\Utility\rda2\rda2.java:21: cannot resolve symbol symbol : class Rda2Server location: class rda2.rda2 Rda2Server serverLib = Rda2Server.INSTANCE; ^ D:\WS\DSDProjects\Utility\rda2\rda2.java:21: cannot resolve symbol symbol : variable Rda2Server location: class rda2.rda2 Rda2Server serverLib = Rda2Server.INSTANCE; ^ 2 errors

Any assistance would be helpful.

Thanks,
