How to use messages in WebDynpro-ABAP

Hi,
How to use messages in WebDynpro-ABAP.
Does it has any class to manage messages like IWDMessageManager or we can just use standard SAP Message types.. like E,W,X,I,S..
I hope it have a message container to display messages.
Thank U for Ur time.
Cheers,
Sam

Hi Sam,
U can hard code the message or u can use the Assistance class's text elements to store the messages.
1) Code to display hard coded message:
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = "Enter the correct Connection ID"
element = elem_flightinfo
attribute_name = 'CONNID'.
2) Code to display message from text element of assistance class:
lv_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = lv_text
element = elem_flightinfo
attribute_name = 'CONNID'.
Where Message "Enter the Correct Connection ID" is stored in Text Element with key '002'
Hope this helps,

How to use Webservice in Webdynpro ABAP?

I tried searching option for importing WSDL file in WebDynpro ABAP. But I am unable to upload it in my component. In service call wizard I can see only one option i.e. to import Function module.
We cant use Webservice in ABAP webdynpro?
Thanks
Nitesh Shelar

Thanks Rich for quick answer.
But my problem is, I have a stand alone WAS without any RFC Function modules and dictionary structures, of backend R/3, on WAS which I wanted to map in my component.
I strongly believe that in case of stand alone WAS I need to have at least backend dictionary structures to begin with my design. I cant use wizard, as I dont have function modules on this system. I have to code for that manually..
So that is why, I was looking for Webservice option..
Thanks,
Nitesh Shelar.

How to exit from a WebDynpro ABAP application and open another url

Hi Friends,
How to exit from a WebDynpro ABAP application and open another url like (www.yahoo.com) in the same window of the WD4 application on click of a Button?
Regards,
Xavier

Hi,
First of all you should create outbound plug in the window you are trying to exit with plufg type "Exit"
Then create method handler in the view with this code
        data lo_view_cntr type ref to if_wd_view_controller.
        data lo_win_cntr type ref to if_wd_window_controller.
        data: l_parameter_list type wdr_event_parameter_list,
              l_parameter type wdr_event_parameter,
              l_val type ref to data,
              l_val_url type REF TO data.
        field-symbols: <fs> type any,
                       <fs_url> type any.
        lo_view_cntr = wd_this->wd_get_api( ).
        lo_win_cntr = lo_view_cntr->get_embedding_window_ctlr( ).
        CREATE DATA l_val type c.
        CREATE DATA l_val_url type string.
        ASSIGN l_val->* to <fs>.
        ASSIGN l_val_url->* to <fs_url>.
        <fs> = 'X'.
        <fs_url> = 'http://your-link.com'.
        l_parameter-name = 'URL'.
        l_parameter-value = l_val_url.
        INSERT l_parameter INTO TABLE l_parameter_list.
        lo_win_cntr->if_wd_view_controller~fire_plug( EXPORTING plug_name = 'EXIT_PLUG'
                                                                parameters = l_parameter_list ).
      You can easily change this logic to exit application instead of redirecting to the site
       just changing to
       l_parameter-name = 'CLOSE_WINDOW'.

How to use RTRIM function in ABAP

Hey,
I have a question on using trim function in ABAP. According to all documents, I should be able to use rtrim as
shorttext = rtrim('abcde-xx', '-xx').
But when I do that, it gives me an error message "Comma without preceding colon (after shorttest?)"
Anyone can tell me why is this happening? how should I use this trim function? And for me to cut off variable's last few character, what else method can I use?
Thank you very much.

DATA : T1    TYPE STRING VALUE 'abcde-xx',
            T2    TYPE STRING VALUE '-xx'.
REPLACE T2 INTO T1 WITH SPACE.
WRITE :/, T1.
result output is :    'abcde'.

Messages in webdynpro abap

hi all,
can any one help me by provinding me with a small example on how to implement messages in a webdynpro application.
Thanks in advance,
chandana.

Hi,
Use the IF_WD_MESSAGE_MANAGER interface .
All messages will be displayed in a dedicated message area.
By default the message area appears at the top of the page.
The message are can be moved like a UI element in a view. You find a UI element (Message Area) in the UI library Pattern. Messages will be placed in this area, if it is available.
Use the WD code wizard to create the required coding to report a message. (Generate Message radio button)
Generated/sample code will look like this.....
   * get message manager
data: l_current_controller type ref to if_wd_controller,
      l_message_manager    type ref to if_wd_message_manager.
l_current_controller ?= wd_This->Wd_Get_Api( ).
CALL METHOD l_current_controller->GET_MESSAGE_MANAGER
RECEIVING
    MESSAGE_MANAGER = l_message_manager
* report message
CALL METHOD l_message_manager->REPORT_ATTRIBUTE_ERROR_MESSAGE
EXPORTING
    MESSAGE_TEXT   = 'REPORT_ATTRIBUTE_ERROR_MESSAGE'
    ELEMENT        = Elem_Flights
    ATTRIBUTE_NAME = 'CITYFROM'.

How to handle events in webdynpro abap

Hi,
can any body explain how to handle the events in webdynpro abap.
i want to know some concepts in general.
Thanks,

Hi Mahesh,
you can create event handlers under the actions tab in you view. evry event handler has an importing parameter wdevent of type ref to cl_wd_custom_event.
you can also create events in your component controller and they can be handled within your views
check cl_wd_custom_event class for details about what all information you get when an event occurs.
for further details you can check out the following links

How to use Adobe forms in ABAP

Hello Everybody,
I have used Adobe forms in webdynpro applications. Now, i want to use adobe forms in ABAP stack. Please provide me steps and guidelines to develop Adobe forms in ABAP.
What should be the infrastructure needed for that?
Thanks in Advance,
Bhavik

Hi Bhavik,
there is extensive documentation on creating PDF-based forms for printing in ABAP Workbench (transaction SFP) on the SAP Help Portal at http://help.sap.com/saphelp_nw04/helpdata/en/d2/4a94696de6429cada345c12098b009/frameset.htm.
The infrastructure is identical (ADS on Java Engine) except that you need an ABAP backend (minimum 6.40) and the corresponding SAP GUI. You also need to create an HTTP connection from your ABAP system to the ADS in transaction SM59 (see ADS Configuration Guide).
Your Adobe LiveCycle Designer installation from the NWDS should be OK, if you are working on the same frontend. (If you have difficulties with Designer, uninstall it and install it with the SAP GUI again).
Note that Web Dynpro for ABAP integration is only supported as of NetWeaver 2004s (going into ramp-up with mySAP ERP 2005 this month), which means that interactive scenarios are more cumbersome to implement in ABAP with NetWeaver 04.
Some of the things you get with the Web Dynpro framework (such as the return of data in interactive scenarios via the WD context) would need to be manually coded when working in SFP, which was designed for output forms.
Hope this helps,
