http connection error using cl_http_client

Former Member — Thu, 07 Feb 2013 16:45:28 GMT

Hello,

i am learning how to set up a connection from ABAP to an external web-server using cl_http_client, beginnig right from scratch.

For testing purposes I therefore have established an IIS7 (Windows7 internet information Service) on my localhost with an IP and

Port. I have created a XML-File in abap and now want to use the http-put method to create a file on the root of the localhost-server.

Below you can see my code. After the create and the send-methode, sy-subrc is always 0 (Zero). Even if I replace the '10.0.0.36' IP in

the create method with some rubbish caracters , the sy-subrc is 0 after the send-method. After the receive-method the subrc is suddently 1

( = http_communication_failure ).

Maybe you can halp me and tell me why the sent-method returns subrc = 0 and maybee you can also tell me how to fix my connection problem.

Help is very much appreciated
