Webservice connectivity issue

Hi,

The requierment is to send data to external system using the webserice, so we have consumed the WSDL file and have created proxy class and Logcial port (in SOAMANAGER Transaction).

When we try to to test the Connection in SM59 by clicking Connection Test button message "ICM_HTTP_CONNECTION_FAILED" gets displayed.

We checked in SMICM transaction both the services HTTP & HTTPS are active.

Also the WSDL file connection is checked using the SOAPUI it works fine.

Is there any confiiguration missing or is there any prerequisite for sending any data using Webservices.

If any one has faced this please let me know how to solve this.

Regards,

Ganesh
