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
