Entity Service test issue (Service Browser)

[Former Member]

Hi,

I'm trying to exchange data between a Callable Object and a WebService method.

I createt a CAF Development Component and importet a webservice. I capsuled a method in an Entity Service (deactivatet local persistency).

When i now try to test this Entity Service through the Service Browser, i get the following error message:

<b>ERROR: No business object instance found</b>

The WebService works fine with the same parameters. I can test it with the Web Service Navigator.

The strange part is: no Entity Service in my System works through the Service Browser test. No self made Entity Service and none of the preinstalled SAP Entity Service.

I always get the same error.

Is this some installation or configuration issue?

Also: i can't find any information about this error in the logs. Although i changed the severity in the visual administrator from FATAL to ALL.

I'm using the NW SneakPreview SP15. Regarding to the tutorial "81 Integrate a Web Service in Your Composite as an External Service*" this should work in the preview version.

Best Regards,

Manuel

Hi,

Last time I had this same problem of yours is because the Entity Service is not properly deployed. Upon deployment, there is some errors happen. What I can suggest is try to redeploy your CAS and make sure no errors happen

Hi,

Please make sure that the build of your DC is without any error. Furthermore please check the log file of the J2EE engine. It's called 'defaultTrace.<#>.trc' where # is a count variable starting with 0. This file is located in a path similar to this one 'C:\usr\sap\<SID>\JC30\j2ee\cluster\server0\log' (where <SID> is the system id, e.g. 'F04').

Open this log file with the notepad and search for notion 'exception', probably you'll get more info about the error.

Hi,

I'm using the WebService (EDMFoundationWS with method getEmployee, exists on SAP Web AS) which is working. i testet it with the WebService Navigator and the ID 20 and got a Employee back.

The build of the DC was successfuly.

In the default trace log i don't get a error message when i'm executing the query from the Entity Service!! There is no log entry within the timeframe i executet this query.

Although i switched the property "DatabaseLogs_Severity" to ALL in the Visual Administrator. (Entries "Dispatcher 0 0_28668" and "Server 0 0_28668" > "Kernel\LogManager").

That's strange. Is there any other "severity switch" regarding to caf i missed??

But, there are Errors within the default trace:

Hi,

what about your permissions for your entity service? Have you deselected it in the designtime? If not, does your user have the correct authorizations (maintained via ACLs)?

Hi,

in the designtime? i deselected it in NWDS during the creation of the Entity Service. I haven't chenged something about security in the browser based caf designtime.

regards,

Manuel

[jan_rauscher]

Hi,

Yes, the CAS perspective in the NWDS is the design time of CAF Service&UI Layer (= CAF Core).

I must admit: I'm running out of ideas, however please check if the external service configuration is adjusted correctly. You can find a decription how this can be done in the tutorial you alread mentioned ('81 Integrate a Web Service in Your Composite as an External Service* (PDF/Service)') in the chapter 'Runtime External Service Configuration'.

Hi,

a colleague meant it seems to be not a technical issue. The Service Browser just don't find any User with the ID 20. This also can be the reason why i won't get a error log entry.

So, if the WebService does this means that the parameter mapping between EntityService and WebService is somehow wrong.

My Mapping:

Input->pers_no/minValue

to Input->ns6:parameters/ns4:getEmployee/ns4:employeeID

Output->Result/pers_no

to Output->ns6:parameters/ns4:getEmployeeResponse/ns4:Response/ns1:employeeID

Output->Result/firstName

to Output->ns6:parameters/ns4:getEmployeeResponse/ns4:Response/ns1:firstName

Output->Result/lastName

to Output->ns6:parameters/ns4:getEmployeeResponse/ns4:Response/ns1:lastName

Output->Result/id

to Output->ns6:parameters/ns4:getEmployeeResponse/ns4:Response/ns1:eMail

Is it possible to Debug the EntityService (setting breakpoints)? What do i have to do?

Best regards,

Manuel

[jan_rauscher]

Hi,

Did you already tried to test the handeling of your entity service with local persistence? Do you face the same issues? If not, please check if the web services are correctly configured in the service configuration. Furthermore please be aware, that the transaction handling on the remote database have to implemented by the web services. CAF does not execute a commit in the backend implicitly.

Hi,

with version NetWeaver04s SneakPreview SP07 it works fine.

I don't know the cause of this issue, maybe an installation issue or something.
