[sleuthkit-users] Java bindings: ClassNotFoundException TskDataException

[<zah...@gm...>]

Hey everyone,
I just started using Tsk. To get a feeling I wanted to try out the sample (Sample.java, see below). I build it with Ant (build.xl, see below). While the build itself is successful I can't get the program to run (java -jar Sample.jar). I am working on a Linux Machine, the JNI libs are in /usr/lib. The file Tsk_DataModel.jar I copied to projectdir/lib.
This is the message I get:
'Exception in thread "main" java.lang.NoClassDefFoundError: org/sleuthkit/datamodel/TskDataException
	at java.lang.Class.getDeclaredMethods0(Native Method)

	at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:486)
Caused by: java.lang.ClassNotFoundException: org.sleuthkit.datamodel.TskDataException

So could anyone help me on that? Thanks.
