Hi Sathish,

Are you getting value in Webservice navigator for the input you have given for executing the model?

hi shabir,

In webservices , i got the result.. .I am not getting the values in my application only..

check your web services method and parameter type. If the signature is different web service will not be execute. check the data type for the input parameters.

Hi,

Everything is fine. I have checked with by creating a sample application using same model. In tht application also i am facing same problem. Is it may be the problem with backend? ???

seems strange after generating the model classes and still not getting output!!

could you try giving input in the try..catch block ?

hi,

use the Messagemanager to check whether the model classes are getting Instantiated .inside the try and catch use

wdComponentApI.getMessageManager().reportSuccess("some message");

and check whether u have invalidated the correct response node.

as u are using the code inside the try and catch , the exception is caught

so in the catch block use the message manager to check whether u are getting any exception.

wdComponentAPI.getMessageManager().reportException("some message"+Exception );

thanks and regards

Hi Satish,

This is a strange scenario. Some possible reasons could be,

1. If the webservice is callinf SAP R3 for data, then while creating a webservice and executing the websercice, you are pointing to different client than the one which you see in wsNavigator.

2. You have not bound the correct input for model execution.

3. You are invalidating the entire request node and not just response node after execution.

4. The model is pointing to wrong webservice or the logical destination defined and has a wrong client(if defined)

5. While Executing a web service, there are some exceptions which was caught within websevice and webservice has not returned any corresponding message in the return type of the webservice method.

6. exceptions caught in webdynpro but not displayed.

and So on and on.

Already you have answered for many of this in the previous section. Please confirm the other things if not answered. also, it would be useful for us if we can get the code used by you.

Thanks ..

are you invalidating the exact output node ?

print size of output node in the try..catch block itself
