Webdynpro Adaptive Web Service Model against a cluster

[Former Member]

Hi All:

We are having an issue with a webdynpro application

We are receiving the following error on an application which is calling a Clustered application from a SAP Composition Environment 7.1. We are trying to get more information about it.

Exception on execution of web service on destination <service_name> for operation 'ZpmrfcChequeoOperario' in interface '<service_name>

We have successfully tested on Development and Test and it is working fine. We have even point the Destination template to the URL used on Test and the application is working fine.

We have tested with the WSNavigator the services was working, but when we enter on the Service Registry and we go the system details we see it is pointing not to the Cluster Virtual mode from the backend but to one of the application mode.

The URL of wsdl binding and target address is correct.We need to discard that there is an error, on the import Adaptive Web Service Model for using external web service in WD Java.

Any ideas or how to debug an error as this, I am lookin

Exception on execution of web service on destination <service_name> for operation 'ZpmrfcChequeoOperario' in interface '<service_name>

We believe it is the destination template url is correct as we have tested from the WSNavigator and it works, but it is very strange.

Kind regards

Hi All:

Finally, what happened is that Destination Templates stored the configuration on a class and that is on memory and cached. We simply restarted the server and then it got the new configurations made which pointed to production

Thank you all for your answers, points given

HI ,

This error might be due to Webservice deastinations are not propertly configured in visual administrator.

Login to visual administator check whether destinations are ok or not?

in VA,Go to Services->Destinations->Select the destination and test it once.

Hi Gonzalo,

Did you set the user Id and password before the execution?

try{

wdContext.currentRequest_<node>Element().modelObject().setInvokerProperty(Stub.USERNAME_PROPERTY, "username");

wdContext.currentRequest_<node>Element().modelObject().setInvokerProperty(Stub.PASSWORD_PROPERTY, "password");

wdContext.currentRequest_<node>Element().modelObject().execute();

wdContext.node<output>().invalidate();

}catch(Exception e){

wdContext.currentContextElement().setError(e.getMessage());

}
