I indeed remember to have seen registered triple collection under /sparql
soon after first run, but then it disappeared.

Is there any way I can register this graph manually using Felix Web Console
/system/console ?

Hi,
Based on the latest decision, I have applied the patch provided by Meric.
The registered graph is also unregistered in the deactivation of
SolrStoreImpl.

Re: Contenthub problems with SPARQL endpoint
Posted by Rupert Westenthaler <ru...@gmail.com>.
Hi,
this is a summary of a discussion I had with Suat on the #stanbol IRC channel:
Components need to register/unregister TripleCollections themselves.
In that specific case line 150 - 157 of SolrStoreImpl should be moved
to the activate(..) Method. The SerivceRegistration returned by
BundleContext.registerService(..) needs to be kept as filed and be
used in the deactivate(..) method to unregister the TripleCollection.
This should solve the reported issue.

Re: Contenthub problems with SPARQL endpoint
Posted by Suat Gönül <su...@gmail.com>.
Hi,
Meric, thanks for the patch. However, I think we need a more general
solution since the patch seems specific to Contenthub. I mean we should be
able to track all registered TripleCollections to be used by SPARQL
endpoint.
@All: As far as I understand single objects registered as services to the
OSGi are not reachable after a restart. As a solution, I think we can
create a "sparql" module within the commons and implement a
SPARQLTripleCollectionRegistry to track the triple collections to be used
by SPARQL endpoint and move the existing code from the commons.web.sparql
into this new module. If there is no other ideas, I will implement this in
the following days.
Best,
Suat

Hi Meric,
I could test how it works, but I don't see any file attached.

Re: Contenthub problems with SPARQL endpoint
Posted by Meriç Taze <me...@gmail.com>.
Hi Maciek,
I am not sure about registering graph by using web console or something
else
except Java API(programmatically) since we get this enhancement graph from
TcManager and give it as an argument to registration function.
I prepared a patch file, but I can not tested it well, if you want, you can
use
attached patch file by using below commands;
> cd STANBOL_FOLDER/trunk/contenthub/store/solr
> patch -p0 -i PATH_TO_THE_PATCH_FILE
this command must patch the SolrStoreImpl.java with output:
"patching file
src/main/java/org/apache/stanbol/contenthub/store/solr/SolrStoreImpl.java"
> mvn clean install -P installBundle -Dsling.url=
http://localhost:8080/system/console
or wait for more stable version, probably ready in next week. You can
follow this issue from https://issues.apache.org/jira/browse/STANBOL-731
Regards,
Meric.
