Example ....Lucene with Java Server Pages?
Hello,
I search for a JSP examples of a simple search application with Lucene.
I try to execute the lucene search as a .jsp file but it doesn't work.
Do you know where can I found information about this topic
Thank You

That's exactly why I don't feel mine is the best
solution. Many people have been asking about the right
pattern for Lucene in webapps, and I'm paying close
attention to those.
To open an IndexSearcher is easy; the hard part for me
is when to close it (to be ready for a potentially new
index.) Perhaps a special HTTP command to trigger
that? I don't know.

James,
Well, if you want to do things right, then you should probably also get
that IndexSearcher (or any other Java code) out of your JSP. :)
You are right, IndexSearchers are meant to be reused. When the index
changes, you need to open a new one, if you want to see the changes.

That demo (results.jsp) opens a IndexSearcher per each
request, which I deem not really the right way of
using Lucene in a web app.
I used jspInit() to initiate a servlet-wide instance:
<%!
IndexSearcher searcher = null;
public void jspInit() {
searcher = ...;
}
%>
Still not complete sure if this is the best way, but
at least not every new IndexSearcher per request.

lucene-1.4.3.tar.gz contains src/jsp. Also try "ant war-demo" in Lucene's
source package.
