[Resolved] Problem generating kea thesaurus...

[gelinp]

Hi,
I parameter the config file (cf. other post about persistance problem of this configuration) then when I send information to calcul first level of the thesaurus exemple OPenKM display the error message :

Founded 0 terms in level 0

I can see a java exception into jboss console :

Code: Select all

It looks like a problem with repository configuration... I've read the documentation about it but I'm not fluently with Jackrabbit... Do I must change parameters into repository.xml file ?

Thank you for your help.

Thesaurus has no relation with Jackrabbit configuration. If you have followed the wiki sample, it should work. If not, something is wrong in the documentation. Which OpenKM version are you using?

Version: 5.1.7 (build: 7085). I'm following tutorial, only the tutorial...

This is my configuration to use kea thesaurus (the same as the exemple):

Code: Select all

kea.thesaurus.owl.file=/vocabulary/inroute.owl
kea.thesaurus.base.url=http://www.inroutenetwork.org
kea.thesaurus.tree.root=SELECT DISTINCT UID, TEXT FROM {UID} Y {OBJECT}, {UID} rdfs:label {TEXT} ; [rdfs:subClassOf {CLAZZ}] where not bound(CLAZZ) and lang(TEXT)="en" USING NAMESPACE foaf=<http://xmlns.com/foaf/0.1/>, dcterms=<http://purl.org/dc/terms/>, rdf=<http://www.w3.org/1999/02/22-rdf-syntax-ns#>, owl=<http://www.w3.org/2002/07/owl#>, rdfs=<http://www.w3.org/2000/01/rdf-schema#>, skos=<http://www.w3.org/2004/02/skos/core#>, dc=<http://purl.org/dc/elements/1.1/>
kea.thesaurus.tree.childs=SELECT DISTINCT UID, TEXT FROM {UID} rdfs:subClassOf {CLAZZ}, {UID} rdfs:label {TEXT} where xsd:string(CLAZZ) = "RDFparentID" and lang(TEXT)="en" USING NAMESPACE foaf=<http://xmlns.com/foaf/0.1/>, dcterms=<http://purl.org/dc/terms/>, rdf=<http://www.w3.org/1999/02/22-rdf-syntax-ns#>, owl=<http://www.w3.org/2002/07/owl#>, rdfs=<http://www.w3.org/2000/01/rdf-schema#>, skos=<http://www.w3.org/2004/02/skos/core#>, dc=<http://purl.org/dc/elements/1.1/>

the folder vocabulary must be under jboss home, the problem could be it not found the file.

Thank you for your help, I resolved the problem :

My path was good :

Code: Select all

/var/www/jboss-4.2.3.GA/vocabulary/inroute.owl

But right files where root.www-data rwxrwx--- and I modify them like that root.www-data rw-rw-rw-

So the problem is that kea doesn't use www-data users group ! So you need to explain into the wiki how kea use right with the file system.

Than you for your help.

The idea is one user called openkm will be who executes jboss application server. And all files under jboss must have rw rights for that user.
