How to call WebDynpro application from an external application

I have an external application, from which an existing webdynpro application should be accessed.
Is there any way i can access WebDynpro application through an URL, so that i can access the same from the external application.
I have to pass a parameter also in the url from extrenal application for which that data should be displayed.
Thanks
Supriya

You can call a web dynpro application from an external app by using the web dynpro application url.
Go to WD application in studio and look at the properties tab, you will find the url.
It should be something like this:
http://<host>:<port>/webdynpro/dispatcher/<namespace>/<dc name>/<application name>

Hi,
SET/GET parameters wont work in WD Envoirment, because WDA programs are executed in browser and that doesnt has a connection to SAP GUI.
You may use the shared memory to transfer work area from the report program, and import the work area agin in the WDA in the WDDOINIT method of the controller where you want to set the fields.
data: send type string.
send = 'enter file name here'.
export send TO shared memory indx(XY) id 'wda'.
CALL FUNCTION 'CALL_BROWSER'
EXPORTING
   URL                          = 'http://SSR11S07.8000/sap/bc/webdynpro/sap/ztest_wda1 '.
And in the WDDOINIT method of the controller, you may import the variable.
data receive type string.
import send = receive from shared memory indx(xy) id 'wda'.
Then you may use the method set_attribute to set the value to respective UI element on the screen.

How to call WDA Application from an other SAP System

hello all,
I have a WDA Application and if the user click on a Button in this Application, i need to call an other WDA Application from an other SAP System.
example: SYStem X01 has a WDA Application and there is a Button in this Application, if the User click on this Button, a WDA Application from an Other System X09 shoud be displayed in the same window, same WDA IFRAME .
can any one tell me how can I do this?
Thank you all

Hi,
As mentioned earlier, you need to pass the host name and port of the second system. If the application name is same, pass the same application name.
DATA: lv_url TYPE string,
       lv_host TYPE string,
        lv_port TYPE string,
        lv_protocol TYPE string.
CALL METHOD cl_wd_utilities=>construct_wd_url
    EXPORTING
      application_name = 'ZWD_APPL_NAME'
      in_host          = lv_host   " host name of second system (X09)
      in_port          = lv_port    " port of second system
      in_protocol      = lv_protocol " protocol of second system
*      in_parameters    = lt_parameters
      namespace        = 'sap'
    IMPORTING
      out_absolute_url = lv_url.
To get the Host, Port and Protocol of second system, wrap the below code in a Function Module(RFC) in X09 and call this in X01 and then pass them to the cl_wd_utilities=>construct_wd_url as mentioned above
CALL METHOD cl_http_server=>if_http_server~get_location
    IMPORTING
      host         = host
      port         = port
      out_protocol = out_protocol.
hope this helps,
Regards,
Kiran

How to call Webdynpro ABAP from Widget

Hello guys,
I want to add an icon to my widget with a link to a webdynpro ABAP application.
However, the link is dependent on the system the user is accessing.
So, I'd like to know if it's possible and what's the best method to do it.
1. is it possible to call a Transcation or a RFC that calls a WebDynpro from the Widget?
or
2. is it possible to retrieve the Widget's default system parameters and assemble the Webdynpro URL dynamically?
Any more ideas?
Thank you and best regards,
Henrique.

SAP uses META Function modules in SRM to get data from R/3 back-end.
For getting Purchase requistion data, use the function modules ->

META_REQUISITION_GETDETAIL Display requisition details
META_REQUISITION_GETITEMS Display requisition items

Calling A Webdynpro Application From Another Webdynpro Application

Hi,
i want to call a webdynpro application from another webdynpro application with sending parameters.
i used this method,
CALL METHOD cl_wd_utilities=>construct_wd_url
    EXPORTING
      application_name = lv_webapp
    IMPORTING
      out_absolute_url = lv_url.
CONCATENATE lv_url '?param1=' lv_param INTO lv_url.
data lo_window_manager type ref to if_wd_window_manager.
data lo_api_component type ref to if_wd_component.

but this method shows the parameters on the address bar.
is there a method to send the parameters to another webdynpro application without show the parameters on the address bar?
Can somebody help me pls?
Thanks.

I've used a server cookie before. This was built for BSP, but it is really usable anywhere. It just writes the data temporary into the database. This way you can just pass one meaningless URL parameter - like a GUID and use this key to read the data (the server cookie) upon initialization of the new application. I generally serialize all the data that I want into one server cookie by serializing a class. I can then restore whatever attributes of the class that I want on the receiving side.

Hi,
it is possible to show Java Web Dynpro applications on a mobile device in general, but the controls and the ui should be optimized for the mobile device.
Safari devices are not officially supported so far for Mobile Web Dynpro.
Supported are Windows Mobile devices and Blackberry devices. I also got some good results with Symbian devices.
You can find more inforamtion on Mobile Always Connected at:
