Controller request to another one which is in another bsp appl. + attrib.

Question

Hi everybody,
how can I call a controller from another controller which is in a separate BSP-application and how can I get some of its controller attributes? I've split the whole application in two seperate one in order not to lose the overview.
Shouldn't be that complicated, or?
Thanks for any help.
Jens

Hi,
For Example u take first application znavigation in that controller do_request u write
method DO_REQUEST.
*CALL METHOD SUPER->DO_REQUEST
data: r_view type ref to if_bsp_page.
dispatch_input( ).
  r_view = create_view( view_name = 'app1.htm' ).
  r_view->set_attribute( name = 'first' value = input1 ).
  r_view->set_attribute( name = 'second' value = input2 ).
  call_view( r_view ).
endmethod.
and do_handler_event()
method DO_HANDLE_EVENT.
*CALL METHOD SUPER->DO_HANDLE_EVENT
EXPORTING
   EVENT           =
   HTMLB_EVENT     =
   HTMLB_EVENT_EX  =
   GLOBAL_MESSAGES =
RECEIVING
   GLOBAL_EVENT    =
DATA: button_event TYPE REF TO cl_htmlb_event_button.
DATA: V_TARGET_URL TYPE STRING,
        W_APP_NAME TYPE STRING.
IF htmlb_event IS BOUND AND htmlb_event->name = 'button'.
    button_event ?= htmlb_event.
  ENDIF.
  DATA: data_input  TYPE REF TO cl_htmlb_inputfield.
  IF button_event->server_event = 'submit'.
    data_input ?= cl_htmlb_manager=>get_data(
                                      request = runtime->server->request
                                      name    = 'inputfield'
                                      id      = 'InputName1' ).
  IF data_input IS NOT INITIAL.
    input1 = data_input->value.
  ENDIF.
   data_input ?= cl_htmlb_manager=>get_data(
                                      request = runtime->server->request
                                      name    = 'inputfield'
                                      id      = 'InputName2' ).
      IF data_input IS NOT INITIAL.
    input2 = data_input->value.
  ENDIF.
Construct the Target URL
        CALL METHOD RUNTIME->CONSTRUCT_BSP_URL
          EXPORTING
            IN_PROTOCOL       = 'http'
            IN_APPLICATION_NS = RUNTIME->APPLICATION_NAMESPACE
            IN_APPLICATION    = RUNTIME->APPLICATION_NAME
            IN_PAGE           = '**/znavigation1/zsecondappl.do'
          IMPORTING
            OUT_ABS_URL       = V_TARGET_URL.
        CONCATENATE RUNTIME->APPLICATION_NAME '/**/' INTO W_APP_NAME.
        REPLACE W_APP_NAME IN V_TARGET_URL WITH SPACE.
Pass the input1 and input2  via URL
        CONCATENATE V_TARGET_URL '?input1=' input1 INTO V_TARGET_URL.
        CONCATENATE V_TARGET_URL '&input2=' input2 INTO V_TARGET_URL.
        NAVIGATION->GOTO_PAGE( V_TARGET_URL ).
  ENDIF.
endmethod.
Activate the first application.
second bsp application:
do_request();
METHOD DO_REQUEST.
   data: r_view type ref to if_bsp_page.
   dispatch_input(  ).
Get the values from source BSP Application which was set via URL
    input1 = REQUEST->GET_FORM_FIELD( 'input1' ).
    input2 = REQUEST->GET_FORM_FIELD( 'input2' ).
*IF  r_view IS BOUND.
r_view = create_view( view_name = 'secondappl.htm' ).
r_view->set_attribute( name = 'input1'  value = input1 ).
r_view->set_attribute( name = 'input2'  value = input2 ).
call_view( r_view ).
ENDIF.
ENDMETHOD.
do_handler_event:
METHOD DO_HANDLE_EVENT.
DATA: button_event TYPE REF TO cl_htmlb_event_button.
DATA: V_TARGET_URL TYPE STRING,
        W_APP_NAME TYPE STRING.
IF htmlb_event IS BOUND AND htmlb_event->name = 'button'.
    button_event ?= htmlb_event.
  ENDIF.
DATA: data_input  TYPE REF TO cl_htmlb_inputfield.
  IF button_event->server_event = 'back'.
     CALL METHOD RUNTIME->CONSTRUCT_BSP_URL
          EXPORTING
            IN_PROTOCOL       = 'http'
            IN_APPLICATION_NS = RUNTIME->APPLICATION_NAMESPACE
            IN_APPLICATION    = RUNTIME->APPLICATION_NAME
            IN_PAGE           = '**/znavigation/zapplication1.do'
          IMPORTING
            OUT_ABS_URL       = V_TARGET_URL.
        CONCATENATE RUNTIME->APPLICATION_NAME '/**/' INTO W_APP_NAME.
        REPLACE W_APP_NAME IN V_TARGET_URL WITH SPACE.
        NAVIGATION->GOTO_PAGE( V_TARGET_URL ).
  ENDIF.
ENDMETHOD.
