Hello,

Lately, I have been using Longwell with a large dataset ( in RDF/XML file).
The result is that it takes ages to de deployed in Tomcat.

That's mainly why I am trying to feed Longwell with data from Sesame.

Firstly, I have initialized my Sesame instance with my huge dataset. (it
took a few minutes to be loaded).
Afterwards, I had a look at 2 old posts to configure Longwell with Sesame:
- http://osdir.com/ml/web.simile.general/2007-07/msg00008.html (which seems
confirmed that Longwell can natively be connected to Sesame)
- http://www.mail-archive.com/[email protected]/msg03671.html (which
includes a patch to enable connecting to Sesame with new properties)

I followed the idea from the first post above. Here are the 3 lines that I
have modified in this file:

longwell.store.type = native
longwell.store.dir = WEB-INF/database
longwell.store.db.url =
http://localhost:8080/openrdf-workbench/repositories/TEST/

But when making my war (maven) and then deploying that in Tomcat, the
servlet stops at this line:
 [...gwellServlet] < index the longwell data (Oms)

Few files are also created in WEB-INF\database:
 - values.id /values.hash / values.dat
- triples-spoc.dat, triples-posc.dta
- etc

I think that these are database indexes. But when opening these file (which
are unreadble), I can't even see one word which are corresponding to my
dataset.

So, I think that Longwell is not well connected to Sesame and that my
settings are incorrects.


For my better understanding, can you let me know if I'm right on the
following points:

 1. store.type = native set the fact that we are not in memory mode and that
the date should be read from a database
 2. store.dir = the path where the indexes will be created.
     (Or maybe the path where they should be read? in this case, do you know
where to retrieve the indexes made from Sesame?)
3. store.db.url = the URL where the repository is available.

> Am I using the right properties name to define sesame URL? (in
longwell.properties)

I will be really grateful if you have the time to take my demand in
consideration.
