Indexes in WAR files (was RE: [SUBMIT] docweb demo app)
Thanks Erik.

Not too sure my question was clear. What I'm trying to do is to create a
searchable reference info system (ie bunch of documentation...:-) that is
packaged into a warfile, dropped into a servlet container and run 'in place'
In other words, I can't have the index on the filesystem but instead, it's
prebuilt and packaged into the WAR file.

So at the moment, Lucene on seems to be able to access file system indexes
(via the FSDirectory) or RAM based indexes via the RAMDirectory (which I
understand has a few problems with arrayindexoutofbounds exceptions...)

What I was thinking about doing was twofold.

1) Modify the Directory classes so that they follow more of a decorator
pattern (as in Directory dir = new RAMDirectory(new XXXDirectory(new
FSDirectory()) instead of the manual initialisation code that I've found on
the list
(http://www.mail-archive.com/lucene-user@jakarta.apache.org/msg00196.html)
and

2) Create a WARDirectory for *readonly* access to a pre-built index stored
in a WAR.


So, am I barking up the wrong tree?


Bye,

Les

You're welcome!

The index is built when someone runs it manually from Lucene's CVS
directory
locally currently. The idea is that it will be incorporated into
distribution builds (perhaps as a separate download since its about a
2MB
WAR) in the future. What I patched doesn't make it automatically
happen...
that comes after there is lucene-dev signoff and it gets rolled into the
main distribution build dependency graph.

Re: Indexes in WAR files (was RE: [SUBMIT] docweb demo app) [ In reply to ]
So you're talking about a servlet container that does not expand the WAR
into filesystem files? Hmmm, I haven't encountered that scenario, but
surely sounds like you're right in that it won't work without modifications
to Lucene to pull an index from a "resource".

I've been embedding indexes into WAR files for quite a while and it works
fine with both Resin and Tomcat 4 - but both of those expand the WAR file
into a filesystem tree.
