Getting Rita.WordNet to work

Question

According to Rita Homepage you just have to download Rita.jar and WordNet-3.1 and add both to thebuild path of your java project.

I did it like that and everytime i try to use it:

RiWordNet wordNet = new RiWordNet(Test.class.getResource("/WordNet-3.1").getPath());

I get:

Answer 1

The data files are no longer supplied as part of the installation. You need to download the WordNet version for your platform and then pass it to the constructor, as documented here.
