How to use dll's(Functions) in java ?

Question

Hi
I want to use the windows : shell32.dll. The declaration is as follows:
Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" ( _
     ByVal hwnd As Long, _
     ByVal lpOperation As String, _
     ByVal lpFile As String, _
     ByVal lpParameters As String, _
     ByVal lpDirectory As String, _
     ByVal nShowCmd As Long) As Long
I load the library via System.loadLibrary("shell32") and define the native methods(in java code):
public native long ShellExecute(
long hwnd, String lpOperation, String lpFile,
          String lpParameters, String lpDrectory, long nShowCmd);
but i get a: java.lang.UnsatisfiedLinkError: ShellExecute. Whats wrong ? For long hwnd i used "0" for the first time, but this shouldn't be the problem. Any idea ?
hte problem i have is to execute a very difficult programm. this need a system(windows) shell to run. so i try to start it with the shell32.dll. in VisualBasic i found my aim using this topic, but it doesn't run in java.
thanks for help.
