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

[Daniel Chirillo <chirillo@xxxxxxxxxx>]

Thanks, Samuel. Is there a way to get/print/display
the request (the XML that is being PUT)? That would be tremendously valuable
in debugging.

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);
