I am fairly new to RTC and am looking for a way to both query and update work items via the REST API :
https://jazz.net/wiki/bin/view/Main/ResourceOrientedWorkItemAPIv2 . I can access the root services document at .../jazz/rootservices but it does not contain the element:

<oslc_cm:cmServiceProviders rdf:resource="https://localhost:9443/jazz/oslc/workitems/catalog"/>

I'm wondering if an admin has to enable the REST API so I can programmatically query the work items? For example, I just want to get a JSON representation of a single work item.

Additionally:

My end goal is to create a web service that will call on the API to update work items which will be hit by a form; at this point I'm just trying to hit the API and am struggling to get traction. If anyone has any suggestions or useful links, I would be grateful.

What is <dc:title> in the received document? Can you post the response content? If you compare what you have got to https://jazz.net/jazz/rootservices, what differences do you notice?

Hey Donald,

The URL I'm using is to access the document:
https://sma-unleash.ratl.swg.usma.ibm.com:9445/jazz/rootservices

I notice that it doesn't have:

<oslc_cm:cmServiceProviders rdf:resource>;
Maybe I'm just confused about the URL I need to access the API of this particular Jazz server, in other words maybe I need to be using a different URL than https://sma-unleash.ratl.swg.usma.ibm.com:9445 .

Fairly new to RTC, any clarification would be great!

The server that you are using has a non-standard configuration. The URL that you used points to JTS, not CCM/RTC. If you check the /jazz/rootservices document, you will see that <dc:title> is "Rational Jazz Team Server". If you then follow the /jazz/application-about link, you will also see that the version is 5.0.2

For this particular server, the context root for CCM/RTC is /ccm or /rtc. Both /ccm/rootservices and /rtc/rootservices return the same document, which confirms that the correct context root should be /rtc. In this document, you will see the tag that you are looking for, and also notice that <dc:title> is "Change and Configuration Management".

In summary, the starting point for your exercise is https://sma-unleash.ratl.swg.usma.ibm.com:9445/rtc/rootservices

 Thanks so much, that is a great help. I might have one other URL question if you don't mind.

I've been trying to login using the Java API Ralph linked me too but I'm having a strange issue. Here's the code: https://bpaste.net/show/109978e4b345 . I've tried every combination to login but I always get the same exception : https://bpaste.net/show/d5c67af6c5a5 which fires on the line:  ITeamRepository repo = TeamPlatform.getTeamRepositoryService().getTeamRepository(repoUri); I'm wondering if it's my URL that's causing it. Also, thanks again!

If you want to use Plain Java start here:

and the related posts. the URI used to login to a RTC Server is usually https://server:port/ccm

Hi Gregory,

I have only limited experience with the plain Java API. Ralph is the expert in this area.

Consider: Open Services for Lifecycle Collaboration Workshop and Developing an OSLC consumer to collaborate with the Requirements Management application.

I tried to collect some information on OSLC and REST here: https://rsjazz.wordpress.com/interesting-links/ even if the blog is really not about REST/OSLC yet.

Note: the domains could be different, but the core methods should be the same.
