Lucene 1.4 (now in release candidate stage) includes built-in sorting
capabilities, so I definitely recommend you have a look at that.
SearchBean is effectively deprecated based on this new much more
powerful feature.

Lucene Users,
I'm using the SearchBean contribution from the sandbox to implement a
Struts application search with Lucene (taking ACO's advice and going
MVC on the demo app.)
Right now I'm having a problem with using any Document objects that
might be available and getting an IOException.
So basically what I'm doing, and pardon the marshalling code, etc.
I have an action that determines the users desired search (internal
via Lucene or external via Google) and forwards appropiately. If the
search is directed to Lucene I create new SearchBean using:
searchBean = new SearchBean(
FSDirectory.getDirectory(
getServlet().getInitParameter( "index" ),
false ),
query );
This bean is put on the request for use in the results.jsp page.
I'm able to quite a bit of work with the bean, determine hits, page
counts, etc. except yank a document and display the indexed fields
(I'm using the org.apache.lucene.demo.IndexHTML) such as "title",
"summary", and "url".
curr position: <%= searchBean.getHitsIterator().getCurrentPosition() %>
<% if( searchBean.getHitsIterator().hasNext() ) {
Document doc = searchBean.getHitsIterator().next(); // BOOM!
}
%>
Any ideas? I only see K. Burton's FSDirectory patch in the archives,
but nothing I don't have from CVS.
Here's the stack trace:
