[Owlim-discussion] Context mixing with Jena API and OWLIM-SE

2012-08-28 Thread Ing. Marek Smid 

Hello,

I am using OWLIM-SE 5.2.5331 with both Sesame 2.6.8 and 2.6.9, and I am 
having troubles with storing in different contexts.


I am using Jena API for accesing the repository, connecting remotely 
like this:

RepositoryManager repoManager = new RemoteRepositoryManager(serverUrl);
repoManager.initialize();
Repository repo = repoManager.getRepository(repositoryId);
RepositoryConnection repoConnection = repo.getConnection();
repoConnection.setAutoCommit(true);
SesameDataset dataset = new SesameDataset(repoConnection);

And then, for each context, I do:
ModelFactory.createModelForGraph(dataset.getGraph(Node.createURI(ctxURI)));

But it seems it uses only the default graph (default context), all data 
are stored in one heap.


However, it works well with remote connection just to Sesame (without 
OWLIM).


Am I doing anything wrong?

Thank you for any help,
Marek Smid

[Owlim-discussion] Exception NoSuchFieldError: NQUADS

2012-08-24 Thread Ing. Marek Smid 

Hello,

I am just starting using OWLIM-SE for a project at Czech Technical 
University in Prague, and I ran into an exception:


When I try to access a repository (on Sesame 2.6.2) configured to use 
OWLIM with the libraries of version 5.2.5331 attached, it gives me the 
following stacktrace:


java.lang.NoSuchFieldError: NQUADS
com.ontotext.trree.nquads.NQuads.clinit(Unknown Source)
com.ontotext.trree.OwlimSchemaRepository.clinit(Unknown Source)
com.ontotext.trree.config.OWLIMSailFactory.getSail(Unknown Source)


Any help would be appreciated.

Hello,

sorry for bothering, my mistake, it was because of Sesame version, it 
needs 2.6.8.


Regards,
Marek

[Owlim-discussion] Problem with querying OWLIM-SE via Jena API

2012-02-22 Thread Ing. Marek Smid 

Hello,

I would like to ask a question about OWLIM-SE.
I downloaded the trial version (we plan to use the full one for a 
project), and I tried to use its Jena API.


I built a NetBeans project, included all necessary libraries, and 
created a simple test. It consists of a TTL of a repository, creation of 
LocalRepositoryManager, SesameDataset and Jena Model - all based on 
provided examples. I loaded it with an extract of DBpedia in a triple 
file. All this seem to work fine, since when I dump the data via 
model.listStatements(), the data are there.


But when I try to use SPARQL query, it fails. I load a simple query with 
QueryFactory, obtain QueryExecution via QueryExecutionFactory, and 
execute it with execSelect(). All OK so far. But since ResultSet has 
hasNext()==true, I try to obtain a solution with ResultSet 
nextSolution(), and this gives the exception:


Exception in thread main java.lang.InstantiationError:

How can I get it working, please? Am I doing something wrong?
