Paul,
If you're creating the index files before or during the build, you can
place them in:
Project->src->main->resources->some-folder->files
Maven will package them up and place them in WEB-INF/classes/some-folder
In your application, you could use getResourceAsStream to load the
information from the classpath.
If you're launching Lucene from within your web application and
periodically building the files, then placing them into
${tmpdir}/lucene is probably the way to go.
. . . . just my two cents.
