Hello,

I have just one basic question:
Is there a way to see the declaration of response.getEntity() function in client project? I just want to debug but I can not go in to that function to see how it works. I was wondering if this is something happens to me may be because of missing files/environment or everyone have same difficulty.

Here is the code how I use getEntity() function to give you an idea:

OslcClient client = new OslcClient();
response = client.getResource(resourceURI, OSLCConstants.CT_RDF);
EntityB resource = response.getEntity(EntityB.class);

Thanks in advance

ClientResponse.getEntity() is an Apache Wink Client method. You could set breakpoints in these methods in OSLC4J if you're still getting back null.

org.eclipse.lyo.oslc4j.provider.jena.AbstractOslcRdfXmlProvider.isReadable(Class<?>, MediaType, MediaType...)
org.eclipse.lyo.oslc4j.provider.jena.JenaModelHelper.fromJenaModel(Model, Class<?>)

If you attach the RDF and the annotations on your EntityB.class, I might be able to help as well.

Hi Samuel,

Thank you very much for your reply. I am using client from ToolAAdaptor to receive entity from ToolBAdapter. respond looks fine actually, but as I mentioned before after calling respond.getEntity() it becomes null.

Can that be because of "ToolBAdaptor" initial in RDF? Since the call is from ToolAAdaptor maybe this needs to be ToolAadapter? Or am I making thing complicated?

I printed out response and this is the result I receive:
<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF
