To call standard tcode in webdynpro( thru webgui) : Assistance class

Question

Hi Gurus,
I have an alv display in which the vbeln entries have link to action control.
i.e when i click vbeln( sales order no), it should open a new window through its/webgui.
1.I am getting following error when i activate , get_execute_location is private/protected.
2. How do i go about the following code:
wd_comp_controller->execute_get_location(
IMPORTING
e_host = lv_host
e_out_protocol = lv_out_protocol
e_port = lv_port ).
Within my method of my assistance class I call an interface in class cl_http_server to procure my host,
protocol and port number.
CALL METHOD cl_http_server=>if_http_server~get_location
IMPORTING
host = e_host
port = e_port
out_protocol = e_out_protocol.
Can some one explain in detail.
Best Regards,
Navin Fernandes.

Hi Navin,
To display a standard tcode in your webdynpro application using  ITS  you can use the following code
DATA: url TYPE string,
        host type string,
        port type string.
*Call below method to get host and port
  cl_http_server=>if_http_server~get_location(
     IMPORTING host = host
            port = port ).
*create URL
  CONCATENATE 'http'
  '://' host ':' port
  '/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction=' 'SE11'
   INTO url.
*get the window manager as we are opening t code in external window.
  DATA lo_window_manager TYPE REF TO if_wd_window_manager.
  DATA lo_api_component TYPE REF TO if_wd_component.
  DATA lo_window TYPE REF TO if_wd_window.
  lo_api_component = wd_comp_controller->wd_get_api( ).
  lo_window_manager = lo_api_component->get_window_manager( ).
*  call the url which we created above
  lo_window_manager->create_external_window(
  exporting
  url = url
  receiving
  window = lo_window ).
  lo_window->open( ).
Hope this helps!
