Yes, use the Java File class:

>>> from lucene import *
>>> initVM(CLASSPATH)
<jcc.JCCEnv object at 0x293a0>
>>> File
<type 'File'>
>>> a=StopAnalyzer(File("foo.txt"))
>>> list(a.tokenStream("foo", StringReader("the foo is bar")))
[<Token: (the,0,3)>, <Token: (is,8,10)>]
>>> list(StopAnalyzer().tokenStream("foo", StringReader("the foo is bar")))
[<Token: (foo,4,7)>, <Token: (bar,11,14)>]

Andi..

ps: the foo.txt in the example above contains:
foo
bar
baz
