Hi John,
Could you please open an issue here https://github.com/rafaharo/apache-stanbol-client including the stack trace of the NPE. I will take a look to it as soon as possible.

I am using the java Stanbol client to query the Stanbol server and extract places, names and organisations. When I add my enhancement engine to the chain I get a null pointer in javax.ws.rs.ProcessingException on the client side during the read entity method . If I comment out the engine metadata editing below, my client software works fine with the extra engine on the chain. UriRef textAnnotation = EnhancementEngineHelper.createTextEnhancement(ci, this); metadata.add(new TripleImpl(textAnnotation, DCTERMS.type, new UriRef("http://example.org/ontology/LengthEnhancement";))); metadata.add(new TripleImpl(textAnnotation, RDFS.comment, new PlainLiteralImpl(" --- this is where I want to add information ----"))); How can I add information to the metadata without breaking my client ? Best Regards, John Crowther
