cannot get demo working

This might be a classpath problem or a file naming problem.
I cannot get the lucene demo working.

I have CLASSPATH=.;c:\jdk1.3.1_01;c:\jdk1.3.1_01\lib
and put both, lucene-1.2-rc4.jar lucene-demos-1_2-rc4.jar into
c:\jdk1.3.1_01\lib

but I always get
C:\lucene-1.2>java org.apache.lucene.demo.IndexFiles <path>
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/dem
o/IndexFiles

I even tried with -cp "lucene-1.2-rc4.jar;lucene-demos-1_2-rc4.jar" ...
to no avail.

Any clues?

You need to point to the jar file itself e.g.
CLASSPATH=.;c:\jdk1.3.1_01;c:\jdk1.3.1_01\lib\lucene-1.2-rc4.jar;c:\jdk1.3.1
_01\lib\lucene-demos-1_2-rc4.jar
I think this should work

You must reference them directly in the classpath.
CLASSPATH=.;C:\mydir;C:\mydir\myjar.jar

Jar files are not picked up by directory references. Anyhow this is
getting a bit off topic. More of a general java use question.

Thanks. The demo works now.
Sorry for this basic Java question, but "put it in your CLASSPATH"
can mean to put it in the path or put it in the CLASSPATH variable.

I struggled with how much detail to cover...eventually I decided to
write it to the modertately experienced java programmer who had no
lucene experience. I'm open to alternative wording patches for anything
in there. (patch first ask questions later ;-) )
