Problem in Running the Lucene web application demo
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.
HTTP Status 500 -

no idea about the webapp demo app, but are you sure you have all the
