DoorsOauthSample - Unable to get the Entity of the Resource Shape for Requirements [message #1124001]

Hi,

I am currently going through the DoorsOauthSample.java example to understand how it works and have come across a problem where I am not able to get the entity details for Resource Shape (this process occurs in RmUtil.java).

In DoorsOauthSample there are lines that gets the catalog, service provider, requirement creation factory and then requirement shape url. Its the last part where the error is happening. The lines where error is occuring is as follows:

[typeURI value is ......./dwa/rm/oslc/shape/requirement......, which looks correct]

-> response = client.getResource(typeURI.toString(),OSLCConstants.CT_RDF);
-> ResourceShape resourceShape = response.getEntity(ResourceShape.class);

When the first line runs, the reponse has some entity value but the message displayed is "Internal Server Error" and the status is "500".

When the second line runs, the resourceShape value is set to null.

I just wanted to find out if any body else has had this problem with the DoorsOauthSample example and if so then would you be able to provide some help.

Thanks.

Your help would be much appreciated Smile

Kind Regards,
Rachita Sakibanda

Hi Rachita,

I did get it running with DOORS 9.5. I had trouble with earlier versions. You are passing a module name to it, not a project? These were my parameters:

-url link_to_dwa -user Administrator -password Password123 -project myModule

The -project is a bit confusing; it wants a module not a project.

I would also suggest you look in your <DOORS Web Access install>/server/festival/logs. There is pretty good logging for any OSLC requests there; might give you more detail. The logging level can be increased by going to festival/config and swapping the log4j.support with the log4j.xml and restarting DWA.

There was a defect with http 500s occurring after numerous OSLC requests. Restarting 'fixes' it. It is properly fixed in 9.5.1.2 so if all else fails, try that - I would give you link but I am not allowed. Google fix central site:ibm.com.

HTH,
Maeve

Hi Maeve,

Yep I am definitely passing a module as I understood at the start that it's the module it requires Smile

.

I will check the logs to see if that helps, hopefully I find the source of the problem Sad

.

Thanks for your help though Smile

. Much appreciated Smile

Hi,

Its me again Smile

.

I did look at the logs and found errors saying:

...Null Authentication...
...authentication.UsernameRequiredException: A username is required...
...FAILED_USERNAME_REQUIRED...

I am unsure as to why it is giving this error as I am able to get the catalog URL, Service URL and Requirements creation factory URL so that means Oauth should be working fine right?

Also the webContextUrl that i am passing is http not https, could this be causing the problem with Oauth as DWA is not secure??

Any help would be greatly appreciated! I really want to get this sample working Smile

!

Thanks.

Kind Regards,

Hi Rachita,

what is the exact version of DWA in use? http should work, but it's possible there is a problem.

hi Rachita,

I have 9.5.1 and I see now when I run the sample I'm getting a http 401 at the end. But it's a long time since I looked at it and it seems I modified the sample a lot. I'll try to spend some time on it tomorrow.

Thanks

.

But are you able to get the resource shape entity without internal sever error 500 as that's where I am getting the error Sad

.

Thanks once again, I just want to get the sample working so I can use it to do other work Smile

Kind regards,

Yes, true I do not have 500s. And I know there is a defect in 9500 where the result is http 500s where it should succeed (200). Try DWA 9.5.1.2 - you'll get it under DOORS on ibm fix central.

Ok, I re-installed Eclipse and the client stuff and it's working for me. Actually it is better than the last time I ran it as now it is creating objects in DOORS, so I think a really useful sample.
I did nothing - added no code except modify of the consumer key/secret.
I'm on 9.5.1 but I would expect 9.5.1.2 to work also. The 500 issue is fixed on both of those.

Thanks, I will try that version and see how it goes Smile

.

Are you able to see the xml content from the REST of Firefox?

I tried it (used the oauth feature) but got 401 unauthorised error so I was unable to see the xml info from the front end (wanting to see it to see the URL links).

Have you used it before?

Thanks.

Kind regards,
Rachita

Hi Rachita,

no, I've never succeeded getting to DWA via RESTClient/Poster etc. oAuth too much of a stumbler for me. I did see Mike did a tutorial on it, but it takes more patience than I seem to possess. Look for 'Doing the OAuth Dance using your browser' on youtube, by OpenServicesDotNet. I'm preferring lyo doing it for me.

Have fun,
Maeve
