Calling URL in webdynpro

Hi Experts,
Am new to webdynpro abap.
In my webdynpro programs I have called the function modules. But now I want to replace that FM by that web service. Is it possible? If possible please send some guidelines...
Thanks in advance.

Chella

Error while trying to call a ABAP webdynpro appl. as a link on html form

Hi,
When I am trying to call a ABAP Webdynpro aplication as a link on html form. I get the following error
Error when processing your request
What has happened?
The URL http:///sap/bc/webdynpro/form_ap/ (Path of ABAP webdynpro application) was not called due to an error.
Note
The following error text was processed in the system DRD : Error in Web Dynpro Runtime System
The error occurred on the application server DRD_06 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:

What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system DRD in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server DRD_06 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server DRD_06 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.

Calling an ABAP WebDynpro Popup from a BSP view

I need to know if the following is possible.
I have a requirement to call an ABAP WebDynpro Popup from a BSP view.
When the Popup is triggered (eg via pushbutton) the BSP will pass data to the Popup, before the Popup is closed the Popup will pass data back to the BSP to be displayed in the BSP view.
I do not want to rely on Portal Events as Portals may not be used, would really appreciate a clean simple solution.

Hi,
any webdynpro application has a URL behind it. Haven´t you tried to call that URL with Javascript code ??
script language="Javascript"
url = "test_page.htm" + "?field=" + param;
window.open(url, "F4window", "width=400, height=400");
/script
You can pass data to the WD application using parameters as I show you after the "?".

RFC call from java webdynpro

Hi,
I'm creating a Java Webdynpro where I call RFC's from SAP.
For the images in the webdynpro, I call the standard SAP function 'CVAPI_DOC_VIEW'
When I execute the function in SAP, I get the url to the contentserver with the correct image.
After calling the same function in my Java Webdynpro, the url is empty.
I've checked the importing parameters after calling from webdynpro and SAP and they are the same.
After debugging, I saw that the function 'CVAPI_DOC_VIEW' is the problem. He's exporting an empty url after calling from the webdynpro.
Does anybody knows the possible fault and solution for my problem?

I'm not an ABAPer but the last time I've dealt with DMS from Web Dynpro an ABAPer wrote a custom function that gets the file content (XSTRING) by sending DMS parameters (documenttype, documentnumber, documentversion, documentpart).
After getting the XSTRING from my Web Dynpro Java, I convert it to byte[] and created URL by using WDResourceFactory.
Hope it helps...

Transaction Launcher : calling URL and fill return values in the UI

Hi SDN,
We have a requirement, I am putting an example of it below:-
1. Call URL www.bank.com/branchlocator.htm?postcode=???????
2. pass postcode of confirmed BP to the branchlocator field postcode
3. the website will return nearest branch post code.
4. Return this postcode from the bank website, back into the webui address field.
Is it possible to achieve the above scenerio? if yes then any guidelines on how to achieve this?
Hope I am clear in the requirement. Any inputs/suggestion will be helpful.
Thanks,
Pankaj

Hi Shai,
the webservice is working well, trying to test it with webservice navigator.
He also returns the correct number of rows (because there appears slider beneath the table output and I also counted the rows), but there is no data displayed in visual composer.
I have got no further ideas, what the problem is...
THank you for your support.
Kind regards, PAtrick.

Calling url from a form - err using ".value" method

I'm trying to call url from a form, which seems to be the subject of many of these Posts.
I have a form with a combo box/LOV and a button. The LOV will read a url into the combo box from a table of url's.
I used the following code in the "OnClick" Java Script Event Handler section, which I pieced together from other posts in this and other forums. (i.e. I'm a pl/sql programmer trying to use Java Scripts for the first time).
OnClick
var X = FORM_DRWING.DEFAULT.A_DRILLDOWN_PATH.value;
run_form(x);
When I attempt to run this form from the "manage" window, I get a run time error "FORM_DRWING is undefined" upon clicking the button. FORM_DRWING "IS" the name of the form!
The runform() function in the "before displying form" pl/sql code section is
htp.p('<script language="JavaScript1.3">
< !--
function runForm(v_link)
window.open(V_LINK);
//-->
</script>');
This code was from yet another Post.
Any help would be appreciated.
Thanks, Larry
null

Hi Larry,
the problem could be that you need to preface your form with 'document.'.
i.e.
var X = document.FORM_DRWING.DEFAULT.A_DRILLDOWN_PATH.value;

How to call URL to collect user input ?

Hi all,
I am writing a Swing applications and at some points, I need to call a URL (external web page) to collect user input. It invokes passing certain parameters to web page so that the web page can be displayed in some certain form. After the user input all data in web page, press "submit", my Swing application needs to get the input back. I suppose that calling URL is trivial but how can I get the input back ? Any input will be greatly appreicated.
Note: the web page will be displayed in one JFrame but it may not related to this problem.
C.K.

response.sendRediresc("http://.......);
public void sendRedirect(java.lang.String location)
                  throws java.io.IOException
    Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root.
    If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
    Parameters:
        location - the redirect location URL
    Throws:
        java.io.IOException - If an input or output exception occurs
        java.lang.IllegalStateException - If the response was committed or if a partial URL is given and cannot be converted into a valid URL

Calling GuidedProcess from WebDynpro ABAP

Hi all
can anybody tell me that how to call GP from webdynpro ABAP.
and what are the advantages and disadvantages in this scenario??
if anyone reply then it would be the great help to me
Regards
Suresh babu

Hey,
You can call a GP from WD ABAP through by implementing a service call from a method that is embedded in your WD. You can refer this link for the same.
http://help.sap.com/saphelp_nwce10/helpdata/en/44/58f9cc0d95311ce10000000a155369/frameset.htm
But you should note here that Data exchange between ABAP WD and GP is not two way but its only one way.

Calling RFC with webdynpro java (in NetWeaver Developer studio)

Calling RFC with webdynpro java (in NetWeaver Developer studio)
Hi,
I want to call only one parameter RFC with webdynpro.
Flight example is very complex.
I want to push a button and pass parameter to RFC input and call RFC.
After execution some message must appaer on the screen.
Is there a step by step .pdf?
Thanks.

Hello Cemil,
There's a seperate Web Dynpro forum for such posts, you should take a look there.
Nonetheless, the classic tutorial is the FlightList. If I was you, I would make sure to do this tutorial step-by-step as it should give you the fundamentals for understanding aRFC. On top of that, it's most likely already available to you on your SAP system...
Here's the link:

SAP BW 7 - Call URL from Right Click Menu

Is it possible to make a http call from the right click menu? I know this was possible in 3.5, but the new code seems to have limited my ability to edit the options that appear when I right click on a field and I need to make a call out to another web server for some external data. Is this possible?
Any information that anyone has about a potential work around would be great!!
Thx.

Kristine,
Have you tried using RRI (Transaction RSBBS)? You can call URL , pass values etc.

Url in links adding calling url as prefix resulting in not found

when i try to call a URL from a menu or document link (either in self or blank) it creates an entry that reflects the new URL being called as a subpage of the calling URL.
so if i am on website www.mysite.com and i link to www.yoursite.com it creates:
www.mysite.com/www.yoursite.com
any ideas would be helpful. thanks.

Do you mean you are coding the HTML yourself?
Firefox will interpret links that do not start with a protocol (e.g., http://) (or with //) as being on the same site displaying the page. For links to external sites, make sure to use the full URL starting with the protocol, or at least starting from the //.
Does that fix it?

Calling a java webdynpro component inside a SAP Workflow

Hi Experts ,
Is it possible to call a java webdynpro component inside a SAP Workflow from the task .
If yes please let me the procedures .
Regards
Sarmistha

Someone has posted this, Take a look if it helps you:
"1. Activate your service in transaction SICF;
2. Activate the WS_HANDLER in SICF (probably you have to do more in SICF, SAP notes will be given to you in your browser when you want to call the service);
3. Make the correct settings in WF_HANDCUST;
4. Do ofcourse SWU3 including webserver activities;
5. Define how you want to call the service via WF_EXTSRV including parameters;
6. Generate a task from your defined service in WF_EXTSRV;
7. Incorporate this task in your workflow definition;
8. Test your workflow. Here you probably get some errror messages that the service cannot be called by for instance inactive ICF services. Activate the correct paths in transaction SICF."
