Problem Accessing Protocol Classes in INBOUND PROXY

[Former Member]

Hi guys.

Im having problems accessing Protocol Classes in a inbound proxy.

I have this code that is copied from:

http://help.sap.com/saphelp_nw04/helpdata/en/a7/3b2a2d45a34a23b75e3b18745c63bc/frameset.htm

 DATA:  lo_server_context   TYPE REF TO if_ws_server_context,
             lo_payload_protocol TYPE REF TO if_wsprotocol_payload.

lo_server_context   = cl_proxy_access=>get_server_context( ).
lo_payload_protocol =
     lo_server_context->get_protocol( if_wsprotocol=>payload ).

But Im getting this error:

The result type of the function method cannot be converted into the type lo_payload_protocol

If I try to get the attachment protocol with this code:

 
DATA: lo_server_context TYPE REF TO if_ws_server_context,
lo_attachment_prtcl TYPE REF TO IF_WSPROTOCOL_ATTACHMENTS.
lo_server_context = cl_proxy_access=>get_server_context( ).
lo_attachment_prtcl = lo_server_context->get_protocol( if_wsprotocol=>ATTACHMENTS ).

Im getting the same error.

What am I doing wrong? It' s code copied fror SAP Library!!!

Thanks a lot.

hi,

you are choosing wrong type for lo_payload_protocol.

you must change like this

lo_payload_protocol TYPE REF TO IF_WSPROTOCOL.
