Error when I load RDF file in Web Services using class Model in Jena
Question
I have a question:
I would like to load a RDF file in my WebService.
I have written this code:
@WebService(serviceName = "Prova_WS")
@Stateless()
public class Prova_WS{
/**
* Web service operation
* @param f
* @param label
* @return
*/
@WebMethod(operationName = "operation")
public String operation(@WebParam(name = "f") String f) {
Model model = ModelFactory.createDefaultModel();
InputStream in = FileManager.get().open( f );
// read the RDF/XML file
model.read(in, "");
ResIterator sublist = model.listSubjects();
Resource sub = null;
while (sublist.hasNext()){
sub = sublist.next();
break;
}
return sub.toString();
}
}
I have done "Clean and Build", "Deploy" and "Test WebService" operations, but I get this error when I insert this value to the operation: "C:/prova.rdf" (without "").

It's executing
Model model = ModelFactory.createDefaultModel();
and giving:
java.lang.ClassNotFoundException: org.apache.xerces.util.XMLChar
That suggests the Xerces jars (xercesImpl -- also needs xml-apis) are not on the runtime class path.
It's better to use "file:C:/prova.rdf" but that isn't the issue here - it isn't at that point.
