This is a bit off topic for the Postgres list... ;)
Make sure you explicitly include the name of the Lucene jar file in your
command line invocation, and any other directories that are required
(normally your current working directory), so for Windows you'd use
something like
java -cp .;{pathto}\lucene-1.4.3.jar YouJavaApp
When you use Lucene in your webapp include the Lucene jar file in
{tomcat_home}\commons\lib or the WEB-INF\lib directory under your webapp.
Hope that helps.

Hi John,
I have had a read through the lucene website
(http://lucene.apache.org/java/docs/index.html) and it sounds pretty
good to me. I should be able to use this in conjuction with my JSP
pages.
This may sound quite dumb to anyone who develops in java, but I need a
little help setting up the demo on my windowsXP machine. I have
installed JDY 1.5.0_07, i have installed tomcat and can confirm that is
is all up and running correctly, as I have already written a few simple
JSP pages.
I have downloaded the lucene package, extracted the package to my C:\
and followed the steps of the demo page:
http://lucene.apache.org/java/docs/demo.html
But, when i try to run "java org.apache.lucene.demo.IndexFiles
c:\lucene-2.0.0\src" from the cmd prompt, I get the following error:
"Exception in thread 'main' java.lang.NoClassDefFoundError:
org/apache/lucene/analysis/Analyser"
I am not sure why this is coming up. I have followed the instructions
on the demo page on the web.
The only thing i can think of is I may have my "CLASSPATH" incorrect.
Can someone help me out with a basic desription if what the classpath
is and where I should point the classpath environment variable to?
Once I have that correct, i think that I may be able to run the demo.
thanks for any help you can provide.

Save yourself some effort and use Lucene to index a directory of your 300
word documents. I'm pretty sure that Lucene includes an extension to read
Word documents, and you can use PDFBox to read/write PDF files. Marrying
the searching and displaying of results to your web application should be
trivial since you're wanting to use java anyway. Lucene has full character
set support and is blindingly fast
If you're looking for a solution to this problem using Postgres, then
you'll be creating a ton extra work for yourself. If you're wanting to
learn more about postgres, then maybe it'll be worthwhile.
