Hi This would happen if Zemanta returns an Recognition where the "http://s.zemanta.com/ns#Target"; instance does not define a value for the "http://s.zemanta.com/ns#title";. (see http://wiki.iks-project.eu/index.php/ZemantaEnhancementEngine Section "Recognition" and "Mapping of Recognitions").
The Code assumes that a value this property MUST BE returned by Zemanta. Can you provide also the logging above this Error and or the Text sent resulting in this. I would like to make some tests before deciding what todo in case of an missing value of the title property. best Rupert On Thu, Sep 1, 2011 at 2:20 PM, David Riccitelli <[email protected]> wrote: > Dears, > > I'm getting an exception when using the Zemanta engine (r1164032): > > (many infos with the response from Zemanta, then) > > 01.09.2011 12:16:54.602 *WARN* [639264024@qtp-303243765-0] > org.apache.felix.http.jetty /engines/ (java.lang.NullPointerException) > java.lang.NullPointerException at > org.apache.clerezza.rdf.core.impl.SimpleLiteralFactory.createTypedLiteral(SimpleLiteralFactory.java:267) > at > org.apache.stanbol.enhancer.engines.zemanta.impl.ZemantaEnhancementEngine.processRecognition(ZemantaEnhancementEngine.java:347) > at > org.apache.stanbol.enhancer.engines.zemanta.impl.ZemantaEnhancementEngine.computeEnhancements(ZemantaEnhancementEngine.java:213) > at > org.apache.stanbol.enhancer.jobmanager.impl.InMemoryJobManager.enhanceContent(InMemoryJobManager.java:78) > at > org.apache.stanbol.enhancer.jersey.resource.EnginesRootResource.enhanceAndBuildResponse(EnginesRootResource.java:179) > at > org.apache.stanbol.enhancer.jersey.resource.EnginesRootResource.enhanceFromForm(EnginesRootResource.java:143) > (...) > > What could lead to this exception? > > BR > David > > > -- > David Riccitelli > ----- > Skype: ziodave > Twitter: @ziodave > LinkedIn: http://it.linkedin.com/in/riccitelli > ----- > Interact SpA > Via A.
