JWNL Wordnet 3.0 configuration and setup

    Just downloaded WordNet 3.0 and JWNL. Running on a mac os x 10.6, eclipse 3.6.2. I couldn't get this thing to work - kept getting the errors below.

    The two things I did that fixed it (beyond setting dictionary_path correctly):
    1. file_properties.xml needs to have this line changed from "1.7" to "3.0"

    <version publisher="Princeton" number="3.0" language="en"/>

    2.  WordNet/dict contains a bunch of files. Apparently, the ones called "index.xxx" need to be renamed to "xxx.exc".
    So, index.noun => noun.exc

    Hopefully that'll help someone else from having the same frustrations I went through getting this thing to work!

    (error message below for reference)
