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

[Daniel Chirillo <chirillo@xxxxxxxxxx>]

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);
