DoorsOauthSample & Lyo 2.4 & DOORS 9.7 & Java 11

JankCode · February 6, 2020, 2:32am

Changes:

Used Java 11,
Replaced wink with jersey
RuntimeDelegate.setInstance(new org.glassfish.jersey.server.internal.RuntimeDelegateImpl());

get a org.eclipse.lyo.client.oslc.OAuthRedirectException on step 3:

 		//STEP 3: Try to access the context URL to trigger the OAuth dance and login
 		try {
 			client.getResource(webContextUrl,OSLCConstants.CT_RDF);
 		} catch (OAuthRedirectException oauthE) {
 			validateTokens(client,	oauthE.getRedirectURL() + "?oauth_token=" + oauthE.getAccessor().requestToken, user, passwd, webContextUrl + "/j_acegi_security_check" );
 			// Try to access again
 			***ClientResponse response = client.getResource(webContextUrl,OSLCConstants.CT_RDF);***
 			response.getEntity(InputStream.class).close();
 		}

Hello and welcome to the OSLC forum!

@jamsden has experience with that sample. Before we start debugging, did you read https://www.eclipse.org/forums/index.php/t/1065558/? In other words, do you go to the URL in the myhostname:8080/dwa/oauth-authorize-token?oauth_token=6d934153-d152-4942-a378-32c9f1549305 and still get the exception after re-running?

If you wish to have an app that does not require restart during the OAuth “dance”, please see https://github.com/OSLC/lyo-samples/tree/master/client-oauth-discovery-dui from @jad.

JankCode · February 13, 2020, 1:37am

still get the exception after re-running? Yes.

Looked at “lyo-samples/client-oauth-discovery-dui at master · OSLC/lyo-samples · GitHub” and its a Web Application. So, I would replace how we create a OslcOAuthClient (using helper) with using the factory?

OslcOAuthClientBuilder oAuthClientBuilder = OslcClientFactory.oslcOAuthClientBuilder();
oAuthClientBuilder.setFromRootService(rootService);
oAuthClientBuilder.setOAuthConsumer(“”, consumerKey, consumerSecret);
oAuthClientBuilder.setClientBuilder(clientBuilder);
oAuthClientBuilder.setUnderlyingHttpClient(new UnderlyingHttpClient() {
@Override
public HttpClient get(Client client) {
return ApacheConnectorProvider.getHttpClient(client);
}
});
client = (OslcOAuthClient) oAuthClientBuilder.build();
bindClientToSession(httpServletRequest, client, consumerKey);

Additionally, DOORS classic 9.7 with DOORS Web Access DWA only supports Oauth 1.0 & 1.0a. Does your client code support these versions?

PS thanks for the help

Hi

So, I would replace how we create a OslcOAuthClient (using helper ) with using the factory?

Yes! But please note that the OslcClientFactory is the new OSLC client (Lyo 4.0) for Jersey. I believe the DoorsOauthSample code you were looking at is based on Lyo 2.4 (and hence Wink)

Additionally, DOORS classic 9.7 with DOORS Web Access DWA only supports Oauth 1.0 & 1.0a. Does your client code support these versions?

The sample code does support Oauth 1.0 (But I am not exactly sure if it support both 1.0 and 1.0a, but at least one of them for sure.)

I tried to build/run lyo-samples/client-oauth-discovery-dui at master · OSLC/lyo-samples · GitHub and got:

Blockquote Could not find artifact org.eclipse.lyo.clients:oslc4j-client:jar:2.4.0

The pom sets:

Blockquote <version.lyo>4.0.0-SNAPSHOT</version.lyo>

So, not sure why the project is looking for 2.4.0?

JankCode · February 18, 2020, 12:48am

The end of the URL needs a “/”

Bad:

-url http://doorshostname:port#/dwa -user username -password password -project module_name

Good:

-url http://doorshostname:port#/dwa/ -user username -password password -project module_name

andrew · February 18, 2020, 6:46pm

Hi,

I cannot reproduce your error with the 2.4.0 deps:

Thanks for reporting the tip with the URL, which README should I add it to?

jad · February 20, 2020, 8:13am

I just tried and cannot reproduce the 2.4.0 deps error either.

JankCode · February 20, 2020, 7:29pm

The Project calls out two REPOs and I do not see org.eclipse.lyo.clients:oslc4j-client:jar:2.4.0?
Do you have a local REPO in your setting.xml or have the jar in your local .m2?

andrew · February 20, 2020, 8:32pm

First, you should not need the 2.4.0 client to run the oAuth discovery app.

Second, before 4.0.0 the client was called oslc-java-client. See https://oslc.github.io/developing-oslc-applications/eclipse_lyo/setup-an-oslc-provider-consumer-application.html for more info.

JankCode · February 26, 2020, 9:23pm

Thanks for the help everyone. So, if I am accessing IBM DOORS, as a OAuth 1.0a client, using the example provided. I should use the Lyo “classic” oslc-java-client:2.4.0? Right? Any plans to re-write the org.eclipse.lyo.client.oslc.samples.DoorsOauthSample for oslc4j-client:4.0.0.M1 ?

andrew · March 6, 2020, 11:27am

No plan to rewrite for now, you and @jamsden are the most likely people to make a PR for its support
