What?
Java won't try to load random files as .class files.
Are you launching Lucene from within the startup process of your
webapp? I don't see any support for loading Lucene indexes from within
a ZIP file (e.g. WAR, JAR) so you might have to bootstrap the
following when deploying:
1. Know where your files are within the WAR
2. In a ServletContextListener -- perhaps the one that actually
sets-up Lucene -- do the following:
a. Unpack each file of your index into ${tmpdir}/lucene (or whatever)
b. Configure Lucene with an IndexReader that looks at ${tmpdir}/lucene
3. Clean-up after yourself during undeploy
