RTC OAuth consumer error

0
Arvind Rangarajan (16●1●3●3) | asked Mar 30 '12, 4:25 a.m.
I am trying to retrieve the OSLC catalog from the RTC url :
https://rtc:9444/ccm/oslc/workitems/catalog using OAuth. I generated a consumer (Inbound) key with a secret.

I supplied this key and invoked the getRequestToken on the OAuthClient but I got back a 'invalid_consumer_key' message.

I skipped this step an invoked the access method, I got back a 'parameter absent' message. I sent the consumer key,secret,realm,oauth parameters as per the OAuth specification.

Can someone please guide me on the correct way to retrieve the catalog ?

Have you looked at https://jazz.net/library/article/635 ?
You might also want to provide more context on what you are trying to do and how.

Thanks Ralph. I will look into the article.

I need to write a client application that lists the Project areas (and downwards like Defects etc) present on my RTC server. I intend to do this starting from the CCM Rootservices and extracting the CM providers. I have been able to retrieve the CCM rootservices document and from that the catalog URL. This is the snippet of the code I use. 


OAuthServiceProvider serviceProvider = new OAuthServiceProvider(RURL, UURL, AURL);

		OAuthConsumer consumer = new OAuthConsumer(null, "secret", "key", serviceProvider);

		

		OAuthAccessor accessor = new OAuthAccessor(consumer);

		

		//Setup the client that is set up with SSL.

		OAuthClient client = new OAuthClient(new HttpClient3(new MyCustomSSLClient()));

		//Attempt to get a request token from the provider

		try {

			try {

				client.getRequestToken(accessor); -> throws exception 'invalid consumer key'

			} catch (OAuthProblemException e) {

				

				Collection<OAuth> parameters = new ArrayList<OAuth>();

				OAuth.Parameter param = new OAuth.Parameter("oauth_consumer_key", consumer.consumerKey);

				parameters.add(param);

				param = new OAuth.Parameter("oauth_consumer_secret", consumer.consumerSecret);

				parameters.add(param);

				param = new OAuth.Parameter("realm", "Jazz%20Team%20Server");

				parameters.add(param);

				param = new OAuth.Parameter("oauth", "OAuth");

				parameters.add(param);

				OAuthMessage req = new OAuthMessage(OAuthMessage.GET, uri, parameters); -> uri is the catalog url

				OAuthMessage request = client.access(req, ParameterStyle.BODY); -> throws exception 'parameter absent'

You might want to consider posting questions like that in the Extending Team Concert forum. That forum is also a good source to search for similar questions. The Advanced Search might be useful too. i would also search developerworks for articles.

I assume you would provide a user ID and a password. you would not need a registration as friend. If you register as friend I would assume you need to set a functional user ID. However, O have not had time to play much with OSLC.

Thanks Ralph - I will look to post it on the other forum. The article link that you provided is also proving to be useful in this regard.
