Hello everyone,
We currently have a Jena TDB and we would like to install a D2R server and
connect this D2R server directly to the Jena TDB.
Do i have to export the content of the whole TDB in a .rdf file and then
import this to D2R server, or is there a way to use an API or a service to
make my

Hello there,
Here is my question.
I have an existing TDB containing triples.
I have a RDF file and i want to update the existing TDB with the data
contained in the RDF file.
If nodes already exist they should be updated and new data added.
Is it possible to do it with the Jena API ?

shouldn't do backups from another JVM (like using the Java API) or likewise
you could have problems.

I solved the problem by removing this line when i retrieve and store data
in TDB :
// Set prefix namespace
model.setNsPrefix(Measure.PREFIX, Measure.getURI()+#);
I still use the tdbloader.bat to restore data. Everything works fine :)
Thx for ur help.

Hello everyone,
I'm using this code to backup a Jena TDB :
FileOutputStream fos = new FileOutputStream(new File(backupFilePath));
TDBBackup.backup(new Location(tdbLocation), fos);
This generate a backup.rdf file
But i really dunno how to restore this backup in a new jena TDB.

Any clue ?

Anyway i still have a question.
Here the changes :

At the end i close the connection as follow :

I have a question concerning transactions.
I dont find any answer in the documentation so here is the questions.

} catch (Exception ex) {
ds.abort();
} finally {
ds.end();}

to initiate this
transfer of data from the journal to the database?
It may also be of interest to the application to hold off this transfer
from the journal to the database until a certain point in time.

We have a problem with the size of the triplestore.
Indeed, after having inserted 15 elements (2ko each one as rdf format) we
noticed that the size of the TDB increased from 192mo to 216mo : 24 mo is
