Hi Robert,
For Lucene Java issues, try [EMAIL PROTECTED], you will get much
better help in the future.
The issue appears to be that you need to include the actual JAR files
in the classpath, the directory containing them is not sufficient.
See http://www.gossamer-threads.com/lists/lucene/java-user/50132?
search_string=ERROR%20opening%20the%20Index;#50132 for a similar
discussion (which also can be applied to Lucene 2.2.0)
Cheers,
Grant

1)I have downloaded and unpacked the Lucene tar.gz file

. . . which is the directory in which reside the two .jar files, core

4)from within my Lucene directory, I issue the following command (as
indicated in instructions at

Any suggestions? Clearly I am a novice in matters Javan . . . but
learning rapidly . . . I feel certain that this
can be resolved with a small "path" change of some sort . . . but
Zeus be damned if I know what it is.
Java program in general appears to be properly installed. Recently
downloaded from the Sun site.
I am able to compile and run other *.java files from my tutorial
directory. . . .
Thanks in advance for any help that might be forthcoming. I've
stepped through the directions several times . . . to no avail.
I have looked at the FAQ and browsed the list archives, but find
nothing so fundamental.
Cordially,
R. Mullin
