It's probably a classpath issue as you say. You added the neo4j-lucene-index-XXX.jar file manually to the classpath, but also make sure the lucene-core-3.0.1.jar is on the classpath. You can also look in the <neo4j-db-directory>/messages.log and see which extensions are loaded tigether with the graph database and which of those failed to load a.s.o.
