Looking at things more carefully, it may be one of your dependent classes that's not being found.
A couple of things to try. 1> when you do a 'jar -tfv <yourjar>", you should see output like: 1183 Sun Jun 06 01:31:14 EDT 2010 org/apache/lucene/analysis/sinks/TokenTypeSinkTokenizer.class and your <filter> statement may need the whole path, in this example... <filter class="org.apache.lucene.analysis.sinks.TokenTypeSink"..../> (note, this is just an example of the pathing, this class has nothing to do with your filter)... 2> But I'm guessing your path is actually OK, because I'd expect to be seeing a "class not found" error. So my guess is that your class depends on other jars that aren't packaged up in your jar and if you find which ones they are and copy them to your lib directory you'll be OK. Or your code is throwing an error on load. Or something like that... 3> to try to understand what's up, I'd back up a step. Make a really stupid class that doesn't do anything except derive from BaseTokenFilterFacotry and see if you can load that. If you can, then your process is OK and you need to find out what classes your new filter depend on. If you still can't, then we can see what else we can come up with..
