eu.planets_project.ifr.core.storage.api.DigitalObjectManager.retrieve()

Retrieve a DigitalObject from the DataRegistry. Implementations of this method are currently expected to set the Title of the DigitalObject to a sensible filename, as this information may be used to write the data to temporary storage systems. TODO Perhaps remove the above, as persisted files should really use the leafname from the URI? @param pdURI URI that uniquely identifies the DigitalObject @return the DigitalObject retrieved from the registry @throws DigitalObjectNotFoundException If the digital object with this URI is not found in the repository

  private WorkflowResult fetchWFResultFromDR(String job_key) throws Exception{
    //2. get the data registry manager and fetch the digital object containing the wfResult
    URI drManagerID = DataRegistryFactory.createDataRegistryIdFromName("/experiment-files/executions/").normalize();
    DigitalObjectManager drExpResults = DataRegistryFactory.getDataRegistry().getDigitalObjectManager(drManagerID);
    URI wfResultstorageURI =new URI(drManagerID.getScheme(),drManagerID.getAuthority(),drManagerID.getPath()+"/"+job_key+"/wfResult-id-"+job_key+".xml",null,null).normalize();
    DigitalObject doWFResult = drExpResults.retrieve(wfResultstorageURI);
    if(doWFResult.getContent()==null){
      throw new Exception("No workflow xml content available.");
    }
    //3. now read the stream into a String and unmarshall the WorkflwoResult object          
        StringBuilder sb = new StringBuilder();
