Hi,
I have 2 web dynpro components.(COMP1 and COMP2). I wants to call  the application of COMP2  from a button click  from COMP1.

2.  Inside the event handler method for the button i have  written the code as given below.
  data str_url type string.
  CALL METHOD cl_wd_utilities=>construct_wd_url
    EXPORTING
      application_name              = 'COMP2_APP'
    IMPORTING
      out_absolute_url              = str_url
  wd_this->fire_to_app_plg(
    url =                               str_url
When i click the button it wont navigate to COMP2. Is there any other step required ?
Please helps me to solve this issue...

Hi,
   To call URL in same window first create an outbound plug in your current window(ex: EXIT_PLUG ),mark this
   EXIT_PLUG as interface and plug type EXIT. Now use the following code in your button action.
data : lr_view_cont TYPE REF TO if_wd_view_controller.
data : lr_win_cont TYPE REF TO if_wd_window_controller.
data : lt_parameter_list type wdr_event_parameter_list.
data : ls_parameter type wdr_event_parameter.
data : lr_val type ref to data.
data : lr_comusg type ref to if_wd_component_usage.
field-SYMBOLS : <fs> type any.
lr_view_cont = wd_this->wd_get_api( ).
CALL METHOD LR_VIEW_CONT->GET_EMBEDDING_WINDOW_CTLR
  RECEIVING
    RESULT = lr_win_cont
ls_parameter-name = 'URL'.
create data lr_val type string.
assign lr_val->* to <fs>.
<fs> = 'HTTP://APPLICATION URL' .                                       "PASS YOUR URL HERE
ls_parameter-value = lr_val.
insert ls_parameter into TABLE lt_parameter_list.
lr_win_cont->if_wd_view_controller~fire_plug(
exporting
    plug_name = 'EXIT_PLUG'
    parameters = lt_parameter_list ).
