Hi

I am a new user to Lucene.

I tried running the Lucene web application demo provided with the source. I
am able to index the files but I get the following error when I try to
search a query from the browser.

    no idea about the webapp demo app, but are you sure you have all the
    required files like the jar in the right place?
