Dear All
Hope someone can help. I'm trying to run the demo's that came with Lucene
(3.0.0). I extracted the tar.gz to a directory /home/paul/bin/lucene-3.0.0
and changed into the directory. The contents of the directory are as
follows:
total 2288

drwxr-xr-x 4 paul paul 4096 2010-02-13 20:00 src
I then run the following command, with the following results:
java -cp /home/paul/bin/lucene-3.0.0/ org.apache.lucene.demo.IndexFiles docs
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/lucene/demo/IndexFiles

I also tried:
CLASSPATH=/home/paul/bin/lucene-3.0.0/
echo $CLASSPATH
/home/paul/bin/lucene-3.0.0/
java org.apache.lucene.demo.IndexFiles docs
This gives the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: docs

Could not find the main class: docs. Program will exit.
I've searched the mailing lists and the problem generally seems to be that
the class path is not set. Is this the issue here. If so what am I doing
wrong? Why does the second example say the class docs is missing when this
is the directory to index? Does this all mean the classpath is not set in
the first example but is in the second?
Alternatively any suggestions as to what the problem is? If it's a java
problem and is in the wrong forum, my apologies. If some one'll point me in
the right direction I'd be grateful.
Many thanks in advance.
Regards
Paul
