Notes/Domino 4 and 5 Forum

Hello,
I'm trying to build a web service to access to a Lotus Notes database. When testing under Eclipse, everything works just fine. But when I deploy my application on my webserver (Tomcat 6.0/Axis 1.4), it just doesn't work anymore.

Here's the error I get :
java.lang.UnsatisfiedLinkError: C:\Lotus\Notes\nlsxbe.dll: Can't find dependent libraries
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(Unknown Source)
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at lotus.domino.NotesThread.load(NotesThread.java:281)
at lotus.domino.NotesThread.checkLoaded(NotesThread.java:301)
at lotus.domino.NotesThread.initThread(NotesThread.java:139)

The system PATH is set to include C:\Lotus\Notes (where Notes is installed), and so is the java.library.path option of the Tomcat server. It must be some very little configuration mistake, since the app worjks when launched through Eclipse, but I spent all day on the problem and wasn't able to solve it.

Any help would be more than welcome.
