The performance of a mapping task might be slow due to the following reasons:
•The Internet connection is slow.
•Endpoint server request is in wait state and the server is processing the request slowly.
The mapping creation might fail due to the following reasons:
•You do not have the permissions to create the WSDL folder or file.
•WSDL is not available in the provided path.
•Endpoint URL is not valid.
•The endpoint is not up and running, because of which there can be an issue with loading the WSDL. Use your web browser to verify if the WSDL URL is valid.
