Once you have instantiated an OSLC client, you can use the UpdateRequirement class to update the content of a DOORS Next Requirement.
The first step is to access the existing content of a DOORS Next Requirement. At this stage it is critical to keep track of the ETag part of the response. This ETag is to reference in the update request, so that DOORS Next can ensure the requirement was not modified by another user meanwhile.
OslcClient client = OslcClients.jazzForm(new UsernamePasswordCredentials("myUser", "myPassword")).create(); // get the existing requirement URI requirementUri = URI.create("https://myServer:9443/rm/myRequirement"); ResourceResponse<DngRequirement> response = new GetRequirement(client, requirementUri).call(); DngRequirement requirement = response.getEntity(); String eTag = response.getETag(); // change the title of the requirement requirement.setTitle(requirement.getTitle() + " (updated)"); // send the update to the server new UpdateRequirement(client, requirementUri, eTag, requirement).call();
