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
