Pointers regarding consuming a external web-service from SAP

Hi All,

I am trying to consume a web-service from an external system using a URL.

Our SAP system version is 4.7. I have created a custom program and calling up the web service using HTTP POST method.

For this I referred the following weblog.

https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/847. [original link is broken] [original link is broken] [original link is broken]

I modified the program according to my requirements and called the web service, but I am facing certain issues.

1. The if_http_client->send method executed successfully (sy-subrc eq 0). But the next call to the method

if_http_client->receive the program shows error.The message is very long one and I am not able to see it fully in debugging mode.

Please help me with the following questions.

1. Is there any way I can read the message returned from the web-service to see what the error was? In 4.7 we don't have the recording function as in 6.0.

2. I have disable the login prompt by calling if_http_client->propertytype_logon_popup = http_client->co_disabled.

If I don't do that it shows me a SAP Web AS login screen. Shouldn't it show me the standard http login screen?

3.In that login screen if I provide my ID password it returns the following message

'Business Server Page (BSP) ErrorBSPexception:Access to URL :<Server>:<80>/ORABPEL/DEFAULT/READDATA1/1.0 is forbidden'

Any pointers what does it mean?

4. This method seems a very lengthy process to me. Is there any other approach to this issue?

TIA

Barada.
