Re: NoClassDefFoundError

My hunch is you don't have the Lucene JAR in the classpath at runtime.

My code works well, in Linux but on Solaris 9 it tanks, I keep getting this exception. Is there anything I can tweak? The code in question I am assuming

is this:

try

{

Query query = parser.parse (request.getParameter ("param1"));

Hits hits = searcher.search (query);

out.println (hits.length () + " results<br><hr>");

for (int i = 0; i < hits.length (); i++)

{

Document doc = hits.doc (i);

out.println (doc.get ("path"));

out.println ("<br>");

}

}

catch (ParseException pe)

{

throw new IOException (pe.getMessage ());

}



Any thoughts?
