how to consume ABAP web service in webdynpro

[Former Member]

Hi,

I have to consume one ABAP web service in webdynpro for Java, I can test & run the web service using Transaction WSADMIN, but how do I use it in webdynpro. I tried using WSDL URL, but WebService Model Creation wizard failed to load the wsdl, I also saved the wsdl file locally & tried, but no success.

Is there any way, we can use ABAP web service in webdynpro.

Thanks in advance.

Deepak.

Hi,

What is the error when the wizard fails?

Do you have any data type that is not supported?

In NWDS, it says "Error in loading WSDl file. Please check error logs for more details".

some part of the log generated is as below

Are you able to access the above link from browser, seems to be a connection issue.

yes, I can open the wsdl using the browser with the same url,

even I am able to test & run the web service using WSADMIN transaction,

which opens it in a browser for test run.

still wsdl is not getting loaded in NWDS.

I also tried to create a web service system in VC, but there also it failed to ping.

Hi Deepak,

First Close Your NWDS IDE then Open NWDS IDE and try to Import Adaptive Web Service Model.

Make sure you are using correct userid and password (ECC System) and your wsdl doesnu2019t contain any space. If it is working from WSADMIN you can definitely import it as a WD Model.

Mithu,

thanks for the information,

but already tried this so many times with no success.

any other idea?

Kind Regards

Deepak.

Hi Deepak,

We have faced same problem. But it is solved just be closing IDE.

Create a new local test project inside it try to import the model and then check whether you are getting same problem or not.
