Re: [lyo-dev] Challenge Adding Affected By Links to Requirements

Daniel,

The code looks right to me. I'd suggest setting a breakpoint in the debugger to make sure the requirement URI and eTag are what you expect. You can also print the response body from the server, which might give more information. They're examples of how to do that in RQMFormSample and RTCFormSample.

I'm trying to create Affected By (change request) links on RRC requirements.  Server is responding with a 412 (Pre-condition failed).  I think the 2 key details to share are: 

1. I am authenticating at /jts first 

2. I'm getting the requirement by first getting an org.eclipse.lyo.oslc4j.core.model.Link to the requirement from its related test case and then passing the URI of that Link to getResource().getEntity(): 

        public HashMap<String, Object> getRequirement(Link requirement) { 

                HashMap<String, Object> theRequirementAndEtag = new HashMap<String, Object>(); 
                ClientResponse response = rrcClient.getResource(requirement.getValue().toString(), OslcMediaType.APPLICATION_RDF_XML); 
                Requirement theRequirement = response.getEntity(Requirement.class); 
                String eTag = response.getHeaders().getFirst(OSLCConstants.ETAG); 
                theRequirementAndEtag.put("requirement", theRequirement); 
                theRequirementAndEtag.put("etag", eTag); 
                response.consumeContent(); 

                return theRequirementAndEtag; 
        } 


3.  I am including the eTag in the update request: 

HashMap<String, Object> requirementAndEtag = myRrcUtil.getRequirement(requirements[i]); 
Requirement requirement = (Requirement) requirementAndEtag.get("requirement"); 
String eTag = (String) requirementAndEtag.get("etag"); 
requirement.addAffectedBy(defectLink); 
ClientResponse rrcResponse = rrcClient.updateResource(requirement.getAbout().toString(), 
                                                        OslcMediaType.APPLICATION_RDF_XML, 
                                                        OslcMediaType.APPLICATION_RDF_XML, eTag);
