Web Dynpro application calling external web server using HTTPS giving error

Hello,
I don't know whether this is the right question in this forum but my ABAP web-dynpro applicaiton is expected to call another HTTP application on external web server through HTTPS. Presently it is calling through plain HTTP but we want to have HTTPS.
Here are the steps that we followed based on the link from help.sap.com
1] Received the certificate files from external web server
2] Created SSL Anonymous client
3] Imported the certificate files under this client and added into the certificate list
4] Re-started ICM
5] Created RFC Destination of type HTTP to connect to external server with SSL option and basic authentication. This RFC destination was working under plain HTTP.
When tried with Test connection it gave error "ICM_HTTP_CONNECTION_FAILED".
Any idea what might be missing. Thanks in advance.
Regards
Rajeev

Used proper certificate after which the error went away

Web Dynpro Application Accessing RFC

Hello,
i have some trouble with using RFCs of remote R/3 system. Perhaps anyone can help a poor SAP-rookie.
I'd like to execute the tutorial number 4 Web Dynpro Sample Applications and Tutorials. Therefor i installed the "SAP netweaver for java trial", and the SAP Netweaver developer studio.
Responding to the tutorial i have to "set up the SLD connection"
Problem 1: in Step 4 i can not open the "cluster tab" - error
So I went on and ignored this problem. At page 10 of the tutorial the user is instructed how to "create a model".
Problem 2: the connection to the SAP system teminates with the error "org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NoClassDefFoundError)"
any ideas?

Hello Sebastian,
Please check if the OSS note 832994 is of any to you.
Please award points if issue got solved.

How to Debug a BAPI from a Web Dynpro application

I have a Web Dynpro application calling a BAPI, and I would very much like to see what data the Web Dynpro application is passing into the BAPI, and then debug the BAPI.
Is there a way to do this? I'm wondering if it is possible to somehow set up the ABAP stack so that on receipt of the BAPI call, it appears on the tRFC queue waiting for execution.
However it is done, I need a way to step through the BAPI on the ABAP stack.
BR,
Tony.

Hi Anthony,
The ABAP runtime environment contains various tools that you can use for analysis purposes, such as for debugging source code. All source code written for Web Dynpro applications in ABAP can normally be tested using the debugger.
To allow it to test other Web Dynpro-specific program entities too, the debugger has been equipped with a special enhancement. In the phase model in the active application, you can typically see the following information at various points in time:
-The structure of the content of the current controller,
-The properties of the UI elements in the layout of the current view
-The currently instantiated component usages
Starting the Debugger
The functions for debugging Web Dynpro entities are embedded in the new debugger. You therefore need to have selected the new debugger in your Workbench settings.
Selecting the New Debugger
1. In the menu, choose Utilities -> Settings.
2. A dialog box now appears that contains two nested tab page areas. Choose the parent tab page ABAP Editor.
3. The settings for ABAP Editor always open with the content of the child tab page Editor. Here, select Front End Editor (New).
4. Now switch to the Debugging tab page in the ABAP Editor settings and select New Debugger.
5. Save your changes and close the dialog.
Starting the Debugging Process
To run an application in debugging mode, you first need to set an external breakpoint in display mode in one of the methods in the component.
Now start a test run of the application from ABAP Workbench as usual.
The method in which you set the breakpoint depends on the purpose of the test run. To debug a view, for example, it is best to set the breakpoint in method WDDOMODIFYVIEW. Provided that the context of the view controller is not filled using a supply method, the view is fully instantiated in the phase model at this point in time.
Selecting the Web Dynpro Tool in the New Debugger
When you start the application, another session opens automatically for the debugger. If you have not yet saved any personal settings with regard to the layout of the debugger, the Editor tool will now appear on the left, with the Display Variables tool on the right.
1. Select one of the three desktops in order to reconfigure it for debugging the Web Dynpro application (see Designing Work Areas).
2. The right-hand edge of the debugger window has a bar of function icons. Choose the Replace Tools icon:
3. In the next dialog box (New Tool) open the lowest node (Special Tools) and choose Web Dynpro.
4. Confirm the dialog box.
On the right of the debugger desktop, you will see that the previous tool has now been replaced by the Web Dynpro debugger. You can save this setting for future debugging activities. To do this, choose Save Layout In the debuggers general toolbar.
Thankyou,
Ramganesh.

Adobe form data not being retrieved by Web Dynpro application

Hi,
I have created an online interactive Adobe form embedded in a Web Dynpro ABAP application. The Web Dynpro application calls a function module to update data in SAP. My problem is that the ABAP code that was generated to retrieve the data from the Adobe form and call the function module does not retrieve the data if it has been typed into any of the input fields. Oddly enough, it does work if the data is entered by using the value helps that have been placed on the form.
I would appreciate any suggestions.
Thanks!
Russell

Use messageboxes on various events to find out when your value dissapeears.
If you´re not sure about the binding, you can always drag/drop from data view tab onto the layout and check the binding which the system generates for you. Just to make sure.

Web Dynpro application - HTTP or HTTPs

Hi all,
when is a web dynpro application called over http and when over https.
I have a web dynpro application (SICF - Logon Standard - not SSL) but the application is sometimes triggered with HTTPS.
How can i find this out?
regards

So If SSL is configured and installend on your System,
you can call your wd-application through HTTPS (beside HTTP) as well.
But if you enable SSL in SICF on the Logon,
only HTTPS will work, HTTP will not work anymore.

Error when initially calling Travel Trip Form Web Dynpro application

Hello all,
we are facing a problem when calling for the first time the Travel Trip Form Web Dynpro application.
In the trace file we get the following error message:
application [webdynpro/dispatcher] Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.tc.webdynpro.services.sal.core.DispatcherException: Wrong Web Dynpro URL: "../WebDynpro/Servlet/<deployableObject>/<application>/xx?..". xx is not allowed without exchange key. Retrieved URI path: /sap.com/esstratri/TripForm/~wd_key890_1246626831816/background.gif.
Exception id: [001E680CB1CE0078000002A600007B4A00046DCCEE3F358A]
This appears when a trip has been initially created and if the user wants to display a travel trip form.
However, this does not appear anymore, if you click on the travel trip form again.

Hi experts,
I am getting the below error while executing my web dynpro application
500 SAP Internal Server Error
ERROR: Access via 'NULL' object reference not possible. (termination: RABAX_STATE)
I am getting the error only when I am calling a method create manufacturer from my web dynpro program. If i comment this code my application works fine
CALL METHOD wd_this->mo_ch_instance->create_manufacturer
EXPORTING
    gi_manufacturer = ls_manufacturer
IMPORTING
    lv_message      = lv_status
i have created a attribute mo_ch_instance of type YSRM70CL_CH_SW_MD where YSRM70CL_CH_SW_MD is the class which has the create_manufacturer method that i am using in my code.
Kindly let me know whats the issue.
Regards,
Vinod

Hi,
if   wd_this->mo_ch_instance is not initial.
CALL METHOD wd_this->mo_ch_instance->create_manufacturer
EXPORTING
gi_manufacturer = ls_manufacturer
IMPORTING
lv_message = lv_status
endif.
Check wether you have created the object for that class r not.

Amr Azim,
You must have logged in thru a dedicated connection to any server through say VPN before deploying.This way the sdm uses the same login as that of already establised connection.
So 'sign of' all connections to any servers before deploying and redeploy your application.Here you will be prompted to supply the sdm password and deployment shall proceed.

Hi Sam,
Have you a DC inside the JDI (Track)? - then it could be that you have an older Version from the files that you check-in into your Track - SAP_JEE.sca , SAP_BUILDT.
If you have an older version of this files in your DC you must check-in this files again from the new Patchlevel and sync the DS's of your project!

Dear Anil,
What type of WD is it ?
Do you get the error when you trigger some sort of event ?
Is it when first launch the WD ?
Can you be more specific and share with us the code where this is dumping ?

Short dump when trying to open FPM for Web Dynpro Application

Hi,
I am receiving a short dump while trying to open a Web Dynpro Application in FPM. I go to SE80 and open the Web Dynpro component 'FPM_OIF_COMPONENT'. I then choose the application '/sapsrm/wda_l_fpm_oif'. I then click Web Dynpro Application -> Test -> Execute in Administration Mode. A new IE browser is opened and I then receive a short dump. The name of the short dump runtime error is 'OBJECTS_OBJREF_NOT_ASSIGNED_NO' and the exception is 'CX_SY_REF_IS_INITIAL'.
I have not used FPM before. I would like to use it to remove the 'Close' button from this application. Do I need to initialize FPM before using it?
Please help.
Thanks,
Jeff

Hi Chinnu,
Your understanding is not correct, he is trying to execute the application /sapsrm/wda_l_fpm_oif'.
Hallo Jeff,
everyone have suggested lots of possibilities. Nothing works for you. I would suggest the following.
Go and execute any other FPM application which uses FPM_OIF_COMPONENT,does it work ?
If it works then you can narrow down that /sapsrm/wda_l_fpm_oif is not working and you can raise a OSS ticket.
If it is not working then you have to see if you have right BASIS versions to use FPM.

Authentication Screen when accessing Web Dynpro Application

Hi,
We are encountering a situation wherein when we call the Web dynpro application, it asks for Authentication. The way we do is a bit tricky. We have the following set up;
1. We access the CRM_IC ( Web Gui) in CRM and from where we try to create orders in the backend system i.e., ECC6.0 (IS_Utilities).
2. For creating orders we launch the FOP ( in our case it is DYNPRO) from CRM. So ECC screen is opened through ITS using SSO.
3. In addition to this we built a web dynpro application to be called from the DYNPRO (step 2).
4. When the Web dynpro application is accessed it asks for Login details though it has already logged into ECC using SSO.
PROBLEM: CRM -- using ITS / SSO --> ECC --> Web dynpro ?? Authentication screen.
Design:
We are using WDY_EXECUTE_IN_PLACE to open the Web dynpro in SAPGUI. It is working fine when we run the Web dynpro application from SAPGUI, only the problem is when we do the above steps 1 - 4.
Tried using the following logic as well but the same result.
CREATE OBJECT viewer EXPORTING parent = empty_container.
CALL METHOD viewer->enable_sapsso
CALL METHOD viewer->DETACH_URL_IN_BROWSER
EXPORTING url = urlc.
cl_gui_cfw=>flush( ).
So is it possible to over come the problem. Basically, we don't want the Authentication screen it should use SSO.
SSO is already set up in the system.
Any inputs will be highly appreciated.
Thanks,
Roopesh
