OSLCClient receiving entity issue [message #1578645]

Hey there,

I am having an issue with receiving an entity through response.getEntity function.

I am quite sure that the ClientResponse is not null and it's entity attribute is not null either but when I try to get entity out of that response I see that the entity properti changes to null and I do not understand how it is happening.

The code and explanation is:
OslcClient oslcClient = new OslcClient();I create OSLC client

ClientResponse response= null;
Entity entity = null;
response= oslcClient.getResource(resourceURI, OslcMediaType.APPLICATION_RDF_XML); get responce and I see the result from other adapter that entity is not null and it is the right entity. But the response entity is not readable here sinde it is inputstream

entity = response.getEntity(Entity.class);Here I see the result entity as null and it also changes the response entity property to null

It looks like I am doing something wrong but I really do not understand what it is. I appretiate any help or suggestions.

Best regards

Hi, D.G. What type of resource are you getting specifically? You probably want to use something like ChangeRequest.class or Requirement.class in your call to get resource. If Entity.class is an OSLC4J annotated class, you'll want to check your annotations. You need at least @OslcNamespace and @OslcResourceShape on the class declaration. OSLC4J will return null if it can't find any resources matching the declared type in the annotations.

If you need, you can debug further by passing String.class when you call getEntity(). Then at least you can see the content as a plain text string.

Good luck,
Sam

Dear Sam,

Thank you very much for the respond. I am using two custom adapters and Entity.class is an OSLC4J annotated class.

I copied class declarations as you said:
@OslcName(ToolBAdaptorConstants.ENTITY)
@OslcResourceShape(title = "Entity Resource Shape", describes = ToolBAdaptorConstants.TYPE_ENTITY)

Unfortunately I am still receiving null for both Entity.class and String.class where response is not null.

When I run code in debug mode I had an message "Source not found." ClientResponseImpl.getEntity(Class<T> line:52) with Edit source Lookup Path.. button.
Does that make any sense for you may be? I am sorry if I am asking something very basic.

best regards

Hi,

I was wondering if any of you used client for adapters other than BugzillaAdapter and have found a way to receive the resources as an RDF/XML. If I use HTML as a media type it is easy to read resource but this is totally against what OSLC tries to do. However I am just not able to use client to receive resource from other adapter. This should be easy as I understand but couldn't find any solution. I appreciate your experienced suggestions if anyone used the clint for custom adapters.

Best regards
