Accessing Webservices from WD - WS Destination Configurations

[Former Member]

Hi All,

We have configured Webservices destinations for exection and metadata and trying to access this from WebDynpro.

We are getting the following error :

com.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception when retrieving the WS invoker using the execution destination 'TestLogonTicket'

hi

when you create your destinations for your webservices in the SOAMANAGER-> Destination Template

you would be providing wsdl url and destination , and in the below you can

find the username and pwd that need to set , you need to select the radio buttons with logon tickets ,

username , password , there , re-check the username and pwd by selecting the radio button with selecting the

radio button username password , and even check the webservice in the WSNAVIGATOR , whether its working

fine , and other thing is there is situation where your webservice may work fine inthe wsnavigator even then there would

be some problem inthe webservice , even check this scenario.

Thanks Murali.

I tested the WS from navigator with both the destinations - Metadata as well as Execution. It works fine.

Is there any specific dependecies which we need to add to work with webservices?

Hi,

Are you using logon ticket security mechanism in Execution destination?

If yes then did you integrate your webdynpro application in the portal? Or make WebDynpro application authenticated?

For testing purpose try to use the metadata destination for both execution and metadata. If it works then the problem is with the logon ticket.

Yes Charan. Iam using Logon Ticket for Execution.

I tried using metadata, it would not work due to authentication issue.

When I change, it still give configuration error as mentioned earier.

Hi,

Thanks all for your suggestions. The issue is resolved.

I recreated destinations mentioning the system and host name for both ( Though I think this is not mandatory ) Earlier I used destinations without these values.

For Metadata Destination which uses UserId/Password as HTTP Authentication , I mentioned the login credentials.

Thanks,

Hi,

Check your webservice destinations whether it is configured properly.

From which system you are getting the web services.

Hi Uma,

Did you create the Destination in Visual Admin?

If you had done, please verify the URL which you gave.

Hi,

Webservice is deployed on CE 7.1 server and the WD application also is deployed on the same server.

Created these destinations not in VA , but in NWA under SOA Management.
