Service call exception; nested exception is: com.sap.engine.services.webser

[Former Member]

Hi,

I am trying to call a webservice from a simple webdynpro for some reason I am getting this error,

Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlUnmarshalException: XML Deserialization Error. XML is not valid. Element [http://session.services.enterprise.mclarensoftware.com]<successful> is required in <createSessionReturn> but can not be found.

My WSDL looks like this,

<?xml version="1.0" encoding="UTF-8" ?>

Any ideas?

Hi Fahad,

First Check the web service whether its working in web service navigator.

Deserialization Error because web service signature change:

Once you generated the Webdynpro model from web service you should not change the web service signature

if you change the web service signature you will get this exception

com.sap.engine.services.webservices.jaxrpc.exceptions.XmlUnmarshalException: XML Deserialization Error.

To solve this you have to re generated the webdynpro model again with latest web service.

I hope this will solve

Regards

Suresh
