jwnl difficulties in installing Relex on ubuntu

[JRowe]

After installing opencog, I'm now attempting to install Relex 1.3.0,
using the latest download from the lp site.
I have it located at /home/relex. I've set the JAVA_HOME env var.

I've manually specified the path for the jwnl libraries in build.xml
like so:
<pathelement location="/home/relex/jwnl14-rc2/jwnl.jar"/>
<pathelement location="/home/relex/jwnl14-rc2/jwnl.jar"/>
<pathelement location="/home/relex/jwnl13rc2/jwnl.jar"/>

Ant reports a successful build. When I run any of the shell scripts, I
get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: net/didion/
jwnl/JWNLException

I'm not sure where to go from here - all dependencies are installed,
code is the latest release, java path is set, ant reports build
success. What am i missing?

I think we resolved everything via IRC, but curtesy means an
email reply ...

Indeed, everything got fixed and I have Relex running correctly. There
were a few things that needed to be done, but essentially, I had to
manually input the path to jwnl in the Relex parameters, both when
compiling, and when specifying libs to be used in the .sh scripts.
After that, be sure you have the JAVA_HOME environment variable set,
and Relex should work wonderfully.
