SMP3 Native OData iOS : ODataServiceProvisioningFailed ?

[Former Member]

Hi Experts ,

I'm using Xcode : Version 6.2, SMP3 SP06 SDK and SMP3 SP06 Runtime Server.

I followed this() article and implemented the sample OData application, When I run the app to simulator I'm  getting the issue like

this, and in the server log it's showing Error :

2015 03 25 15:22:49#+0530#ERROR#com.sap.gateway.core.ip.provider.data.CamelDataProvider##anonymous#http-bio-8083-exec-7###[Gateway][TECHNICAL][ODataServiceProvisioningFailed]:Failed to Provision Odata service. com.sap.gateway.core.api.exception.TechnicalException: DestinationConfigurationException- exception occurred while getting the destination |

Please help me to resolve the issue.

Thanks & Regards,

Vamsi K .

Just few things:

1. When calling the https SMP URL and using port 8081 from POSTMAN or Rest Client, just be aware if you are using the self-signed certificate, you need to import the SMP cert into the Trusted Certificate Authorities in the browser, otherwise, you won't be able to register.

2. When specifiying the X-SMP-APPCID header value, you need to provide a value ot it or remove it and SMP will populate it automatically for you.

Thank you

First do the full test in REST client then you can test the same in simulator,

1. Just to make sure, have you created a destination of type JPA under DESTINATION tab in gateway cockpit and added it to ESPM service?

Also, are you able to execute https://ipadd:8083/gateway/odata/sap/EspmService;v=1/SalesOrderItems in the browser?

2. Once you are done with the registration through REST client, are you able to retrieve record in REST client for same entityset (lets say SalesOrderItems) ?

URL: https://smpserverip:8081/appid

Method: GET

headers:

     Authorization: smp user credentials

     x-smp-appcid:

     content-type: application/xml

To create destination  type JPA, I'm not using Persistence Layer to persist or fetch the objects in my backend,

So to configure the service under JPA what are the steps I need to follow to access the service .

Hi Vamsi,

If i am not wrong, you are using predefined odata service ESPM. right? To make it work, you have to define Persistence Unit com.sap.espm.model under destination tab. Once you are done, you have to add this destination to the existing odata service EspmService.

Hi Vamsi,

Can you share the screenshot of GET request? I am able to receive 200 ok response and also for each entityset.

Make sure you are passing proper values in the header sections.

Note: I suggest you to hide ip address/server related info.

Hi

I skipped the X-SMP-APPID step in the REST client, Now I'm getting the response

But while running the application getting previous DBHelper calss not loaded issue.

Thanks in advance,

I am not sure what might have missed in code section. Maybe can give more inputs.

[Jitendra_Kansal]

Hi Vamsi,

Please check below once:

1. Are you able to ping app id (in admin cockpit) for the given odata service?

2. Do you see a response when you run http://smpserver:port in iOS simulator?

3. Are you able to register the same app id through rest client? and getting backend info? (you may refer )

Let me call for more inputs.

JK

Hi Jitendra kansal,

1. Are you able to ping app id (in admin cockpit) for the given odata service?

2. Do you see a response when you run http://smpserver:port in iOS simulator?

And in the Last step It's not allowing  to POST method

Can you guide me to solve this ..

Thanks in advance,

VK.

[Jitendra_Kansal]

Since you are trying with an HTTPS call, can you check if you are able to run https://ipaddress:8081 url in the PC browser? Do you see same response what you got in simulator?

I also suggest you to clear cache and cookies for both rest client and browser and then try. Sometime advanced REST client behaves strange, you may also check in POSTMAN (Postman - REST Client - Chrome Web Store).

Give a try with http and 8080 port while registration instead of https and 8081.

Hope this helps.

Regards,

JK

Yes, After pinging the https://ipaddress:8081 in the Postman -REST Client SSL connection was enabled and Registrations occurred , Now in the simulator I facing 403 issue

And I need clarification regarding end point url in Admin Cockpit and gateway Management Cockpit.

Below points to be checked again:

1.  Just noticed that you have white-listed Odata url (exposed via integration gateway).

http://ip:8080/gateway/odata/sap/EspmService;v=1

From SMP3 SP04 runtime onward, all odata services URL listen on HTTPS and Admin port (8083/8084). Cross check it once by clicking on below,

for me its like https://smpserver:8083/gateway/odata/sap/ESpmService;v=1

2.  As you are adding IGW odata url while creating app id in Admin cockpit, have you checked INTERNAL option under BACKEND tab for the same app id?

3. When exactly you are getting 403 error? During registration or accessing backend data?

1. https://192.168.1.8:8083/gateway/odata/sap/EspmService;v=1  Getting response like

2. Yes I'm giving above url in BACKEND connection tab and checking the INTERNAL option for same app id.

3. 403 issues was occurred when i clicked twice Registration button, After adding

else

        [self.downloadDataButton setEnabled:YES]; condition to startRegistration() method  Data Download Exceptions raised.

4. When the app launched on simulator for the First time hit to Register user connection is enabling in the Admin Cockpit. It means I'm hitting the service, Now I modified the code in Register user click event like

- (IBAction)startRegistrationid)sender {

    NSError *error = [self.controller initialiseSMP];

    if (error) {

       [self displayError:[error debugDescription]];

    }else

        [self.downloadDataButton setEnabled:YES];

}

So enabling the downloadDataButton, And after clicking this button new issue raised

And Once again I hit the Register user it's showing new exception
