Wouldn't this be a good case for the JarDirectory implementation
somebody asked for?
The index could then be statically written in a jar file downloaded
with the applet (the original mail refers to static offline HTML
files).
It could even be a great idea for improving the Maven site-plugin :-)
[I mean: when you create the Maven generated site a Lucene based
plugin could index it, create the jar index and then add the "applet"
to the Maven pages]
I have no idea what was asked since I just registered to this mailing
list,
but what I would like to end up is my HTML folder with our software
documentation, then a search.jar file which contains all my index and
then, with a simple java applet be able to query such file and
provide results always in the applet page.

Hi Paulo,
The main problem is that Lucene needs to store its index on a disk
which under normal circumstances an applet may not read. The
applet operates in a sandbox, which only allows "safe" operations.
Reading and writing to disk is not allowed. An applet can only get
resources from the host it came from.
As Lucene does not allow an IndexReader to be created for a URL, I
guess it's not possible in a normal applet environment. Or you
should dive into the IndexReader code an write your own
IndexReader for remote indices.
What you can also do is sign your applet; if a user accepts your
applet as safe you can run it as any other Java application
(download the index from a webserver to a temporary location and
query it for example).
But I am usually quite sceptic with accepting signed applets from
unkown distributors; as it is like leaving your door open for
complete strangers ("of course you may delete all my files on disk").
Are you going to put your applet on a website, or do you want to
distribute it on e.g. a cd? If I would buy some software from you
on a cd, I would more likely accept a signed applet than if I
would visit some obscure homepage.
Regards,
Dolf

Subject: webserverless search with lucene on offline HTML doc
Hello,
I would like to figure out if it is possible to write a java
applet able to search with lucene through an HTML
documentation WITHOUT having a webserver installed on the
system and on multiple platforms.
So I have a set of static offline HTML files forming a
software documentation, would like to index it and search
through it from a browser without having to install a web
server and on various platforms (osx/win32/linux) Is that
possible at all?
Thanks and sorry for the basic question,
paolo
