I got the LuceneInAction.zip, extracted the highlighter-dev.jar and

TermQuery termQuery = new TermQuery(new Term("field", "fox"));
QueryScorer scorer = new QueryScorer(termQuery);
Highlighter highlighter = new Highlighter(scorer);
TokenStream tStream = new StandardAnalyzer().tokenStream("field",
new StringReader(string));
String s = highlighter.getBestFragment(tStream, string);
System.out.println(s);
and I get this error...
Exception in thread "main" java.lang.NoSuchMethodError:

Am I using the correct jar? After looking into the src files, I
want to say that the TextFragment constructor (from the jar file)
take only 2 params, but the Highlighter or TokenSources is trying
to pass it 3 params, but I am not sure of any of this? Can you
make sense of this?
My hunch is you've got another Highlighter JAR in your classpath.
The LIA code compiles just fine against the highlighter-dev.jar it
contains, so I can only presume you've got something mismatched.
