Hello Team,

I had used DoorsOauthSample example to get the requirements from doors 9.5.1 version and I can perform other operations like create/update successfully.

But when I start using this example for 9.6.1 doors version its failing at

RmUtil -> lookupRequirementsInstanceShapes method

ResourceShape resourceShape = response.getEntity(ResourceShape.class);

The above line returns null.

I had compared the xml responses for 9.5.1 & 9.6.1 versions but could not see much differences.

Why this getEntity failed to get the response in ResourceShape pojo format even though the responses looks similar.

I have pasted first few lines of xml responses below for both versions,

in doors 9.5.1 :

..........

If you see the above response only addition in 9.6.1 version is
xmlns:doorsAttribute="http: //jazz.net/ns/rm/doors/attribute#">
<oslc:ResourceShape

But is this causing the issue or is there any property do i need to set for fixing this issue?

Please help me to fix this issue.

Thanks in advance.

Since you have the code, try to first print out the response to be really sure of what you are getting back.
For example, replace

response.getEntity(ResourceShape.class);

With
response.getEntity(String.class);

And read the content.

This will break the code after it, but it's a debugging step

Hi,
Thanks for your response.

In the above question I had mentioned the partial responses of the different versions as well. and the differences.

i.e I had already printed out the contents using getEntity(String.class).

P.S - Even though the responses looks almost similar but still the API unable to parse it.

Is there any other possibilities to resolve this issue.

I don't see any big change in https://www.diffchecker.com/NCxkDPIf

We don't have experience with the exact same type of error. Please make sure Lyo logging is configured properly (ie there is no error messages like "Defaulting to no-operation (NOP) logger implementation" or "SLF4J: Class path contains multiple SLF4J bindings"). Also, please set the level to DEBUG or TRACE until you figure out the problem.

I would actually pay more attention to the Doors log files because that's the component you changed.

Hello All,

I have tried using oslc4j-core 2.4.0 and 4.0.0 libraries. But still the same issue persists.

It looks like the JenaModelHelper class from oslc4j-jena-provider is unable to unmarshal the response to ResourceShape class.

Is there any alternative is available?

Did anyone find same issue?

Please help me to resolve this issue.

Thanks
