Calling Web Service from a BSP

[Former Member]

Has anyone successfully called one of the Google search engine web services from <b><u>6.20</u></b>? Or any external, non-R/3 web service for that matter? When I run test connection on a RFC destination type G (HTTP connection to External Server), it returns ICM_HTTP_CONNECTION_FAILED message. I am using api.google.com for Target Host and /search/beta2/ for Path Prefix; all other fields are blank/default. I was able to setup the RFC destination for type H (HTTP connection to R/3 system) correctly and run the sample ABAP web service client program (from SAP Help which calls STFC_CONNECTION).

Any help will be appreciated.

Thanks, Pradeep

Does your company use an Internet Proxy? Have you setup the global or RFC specific proxy settings?

This is what we had to do. We were calling a psedo webservice in 620 via HTTP Client methods and we had to setup the Proxy settings.

See the following weblog for details:

But keep in mind that even if you are able to make the connection that the WebService will most likely require a SOAP response and request. There are some ways to do this in 620, but it is a lot of development on your part and it is not forward compatible with 640. In 640 you can generate Proxy Classes - which makes calling external webservices very easy.
