Possible to pass in OntModelImpl instance as one of the argument in
a web service method?
Hi all,
May I know will it be possible to pass in OntModelImpl instance as one of the argument in a web service method?
When I create this web servvice and deploy it, it is throwing deployment exception claiming that :"java.lang.IllegalStateException: Cannot build JAXB context.....com.hp.hpl.jena.ontology.impl.OntModelImpl does not have a no-arg default constructor....com.hp.hpl.jena.rdf.model.impl.ModelCom not have a no-arg default constructor......com.hp.hpl.jena.enhanced.EnhGraph does not have a no-arg default constructor." .
After that, I had try to add in the public no-arg default constructor in OntModelImpl, ModelCom, EnhGraph class, and this time the web service was able to deploy but then I had another exception when i running this web service :
"javax.xml.ws.WebServiceException: javax.xml.bind.UnmarshalException: Unable to create an instance of com.hp.hpl.jena.ontology.impl.OntModelImpl

There is no support for marshall/unmarshall of OntModels, they are not
serializable in the java sense. You would need to write a wrapper class
that serializes by writing out in one of the standard RDF syntaxes
(compressed n-triples for example).
