Re: [lyo-dev] Eclipse Lyo with IBM Rational Change 5.2.x is not able to authenticate
Hi Miguel,

It would probably make sense to ask in a forum about Rational Change such as:
    http://www.ibm.com/developerworks/forums/forum.jspa?forumID=1508

Having said that, I asked around a bit and seems that OAuth was added in 5.3 and suggest that you try the latest fixpack 5.3.0.5

Best of luck with it

Dear all,


I hope that someone could help me with the following issue:
A colleague of mine has IBM Rational Change 5.2.0.8 installed on a server and I'm trying to connect to the server by using Eclipse Lyo. (Note: there is no additional IBM product installed in the infrastructure, e.g. Jazz framework). 

I'm trying to use the RTCFormSample.java example to get access, but the problem that I could spot is related to the authentication (it is not able to get the OAuth URLs).
Following exception is raised:
SEVERE: Unable to access the Jazz rootservices document at: https://servername.com/rootservices
org.eclipse.lyo.client.exception.RootServicesException: OSLCC003: An error occurred processing the root services document.  Server location: https://servername.com.

Caused by: org.eclipse.lyo.client.exception.ResourceNotFoundException: OSLCC004: The requested resource could not be found.  Resource: https://servername.com  Value: http://jazz.net/xmlns/prod/jazz/jfs/1.0/oauthRequestTokenUrl.

at org.eclipse.lyo.client.oslc.jazz.JazzRootServicesHelper.processRootServices(JazzRootServicesHelper.java:200)
... 2 more


The rootServices file contains the following information:
<?xml version="1.0" encoding="windows-1252"?>
<rdf:Description
<oslc_cm:cmServiceProviders rdf:resource="http://131.176.192.51:8602/oslc" />

<jfs:oauthDomain>/jazz</jfs:oauthDomain>
<jfs:oauthRequestConsumerKeyUrl rdf:resource="/jazz/oauth-request-consumer"/>
</rdf:Description>

In the JazzRootServicesHelper.java file, I noticed that it also asks for the following predicates: oauthRequestTokenUrl, oauthUserAuthorizationUrl, oauthAccessTokenUrl.

Since I'm working not with the most recent Rational Change, I'm guessing the problem is related with source code and not with the server configuration.

Anyway, could please sombody tell me how I can troubleshout this problem? Is it possible to use Lyo with IBM Rational Change 5.2.x??

Cheers,
Miguel
