RFC Indentification in R/3 from web dynpro

hi experts,
Could u tell me Wether there is any system variable SY-* or any function in sapr/3.so that we can easily know that which model from web dynpro means wether it is rfc or web service model?
thanx in advance.
regards,
pp

Hi,
Since all the inbound calls are via RFC function modules ,I don't think any system variable will be able to differentiate the call.You can think of having a inport parameter to identify the call .

Calling Remote-Enabled JAVA Module from Web Dynpro Java

Anyone have a clue how I can call a Remote-Enabled JAVA Module in ECC from a Web Dynpro Java app? I'm on Portal 7.0. When I try and create an Adaptive RFC model in NWDS and put in the Function Module name (CFG_API_FIND_KNOWLEDGEBASES) or its Function group, that RFC is not returned for me to import. Can I not use this method to get at this function?
(I CAN call this function module and run it from the old SAP Business Connector software. That, however, does not help me get it into my Web Dynpro app.)

If anyone stumbles upon this thread, the long and short answer is you can't call a Remote-Enabled JAVA module in SAP from Web Dynpro Java.....using Adaptive RFC.
You can, however, if you create your own session and function call directly in Java code and give up on being able to use Adaptive RFC.

How to get the Response Code when a URL is launched from Web Dynpro

Hello Experts,
I have a Web Dynpro Application in which in one of its views i have an IFrame UI element in which i will show a resource stored somewhere ..
But before showing it i want to check if the resource actually exists. For this i have to check the HTTP Response code from Web Dynpro Application without setting it in the Iframe..
I am using the following code to get the Response Code:
try{
URL url = new URL("Some Url");
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
wdComponentAPI.getMessageManager().reportSuccess("Response code ="+connection.getResponseCode());
}catch(Exception e){
wdComponentAPI.getMessageManager().reportSuccess("Exception");
Now the Problem is whatever response Code occurs 403 (for No Proper Authorization), 404 (for Resource not found) etc..
i always get Response Code= 500 (which is for Internal Server Error) shown in the messgae i have printed.
Please let me know the correct way of getting the Response Code from Web Dynpro.
Also my resource is lying on a SAP Portal 6.4
Best Regards
Sundeep

Hi,
Check this code from /thread/5242768 [original link is broken] if it works.
try{
URL myurl = new URL("http://calendar.google.com");
URLConnection connection = myurl.openConnection();
if(connection instanceof HttpURLConnection) {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
HttpURLConnection.setFollowRedirects(true);
httpConnection.setRequestMethod("HEAD");
httpConnection.connect();
System.out.println("Response = "+httpConnection.getResponseCode());
catch(Exception e) {
// print exception

Hi
you can use function module
data   ls_input_container TYPE swr_cont.
data   lt_input_container TYPE TABLE OF swr_cont.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
    EXPORTING
      task            = ptask
    IMPORTING
      return_code     = lv_return_code

    TABLES
      input_container = pinput_container
      message_lines   = lt_message_lines
      message_struct = lt_message_struct.
where you pass the data in imnternal table "pinput_container" as
ls_input_container-element = 'KUNNR'.
ls_input_container-value = ls_skna1-kunnr ."wd_this->lv_kunnr.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'CLUSER'.
ls_input_container-value = lv_cluser.

CAF DB Update for CAF Entity Service from Web Dynpro

Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailID.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro.
Within the context of component controller of Web Dynpro the structure is like
APerson
     |_ personId
     |_ personName
     |_ personAddr
     |_ contactsRef
                |_ phoneNo (Under contactsRef)
                |_ cellNo (Under contactsRef)
                |_ emailID (Under contactsRef)
So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
java.util.List ls = new ArrayList();
for(int i=0; i<4;i++)
AContacts contact = ContactsServiceProxy.create();
contact.setCellNo("9092130156");
contact.setEmailID("[email protected]");
contact.setPhoneNo("432258");
contact.getAspect().sendChanges();
ls.add(contact);
person.setRelatedModelObjects("contactsRef",ls);
person.setPersonID("9999");
person.setPersonName("xyz");
person.setPersonAddr("ABC, KOL");
wdContext.nodeAPerson().bind(person);
person.getAspect().sendChanges();
CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards
Chandan

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Calling Batch input from Web Dynpro - any alternatives for table updates?

Hi!
I am asked to create a screen in Web Dynpro for the GJ30 transaction (JV Cutback mapping of WBS' elements). I created a remote enabled function module which call batch input for GJ30 . Testing the Function modules direclty goes fine, but not calling the function module from WD. then I get the same error message as when I once tried to call SAP GUI from Web Dynpro ( Call transaction /submit program).
My next step is to try to create a batch input session (instead of call transaction) and run it using rsbdcsub, and then check the result of the run. But maybe this will fail of the same reason as well, and I suppose this will make the user waiting longer for the response .
I read somewhere that Web Dynpro does not support batch Input. But what can you do when there are no standard BAPI's for the update you want to do in SAP ? We are not supposed to do direct table updates.
Anyone who have struggled with the same issues and found a solution??
regards, Tine

Hi,
as BDC is calling screens and in Webdynpro ABAP you cannot use SAP GUI sceeen, you are getting short dump.

Trigger File Generation to a Server from Web Dynpro Application

Hi Everybody! Hope you had a good new years eve
Is it possible to generate a File on a Server outgoing from Web Dynpro?
I tried to use GUI_DOWNLOAD. But as I couldn't use the GUI_DOWNLOAD from the Web Dynpro, I wrote a Report "ZCMI_EXPORT_FILE" that generates a Text-File. When I start the Report by myself, the file gets generated. All fine.
To be able to generate the File from Web Dynpro, I created a Batch Input Function Module, that I call in the Web Dynpro. The File is not created and it does not show any errors.
Do you have any idea how i can get this working? I'd also be happy with a different approach.
Best Regards and Thanks,
Steffen

HI,
GUI_DOWNLOAD does not get's executed in the Backgroud.
there is no way to do it as a background job.. create the folder.. transfer the file to the application server in the backgorund using OPEN DATASET... use the tcode CG3Y to download the file from the app server to your folder..

Authorization error calling a XI web service from Web Dynpro

Hi all,
I'm trying to communicate to XI from a Web Dynpro application but I get an Unauthorization error (401).
I've generated a WSDL in XI and import it to web dynpro as a new Model. But when a I call the web service, the exception "Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized." appears.
I don't know how to pass the right user and password from Web Dynpro, I've tried the web service from SOAP client tools and it works fine.
I'll apreciate any help.
Regards,
Diego.

Hola mi nombre es Luis,
Creyendo que eres español te escribo en tal idioma.
He visto que a ti también te devolvía un error de autentificación 401, y que lo subsanaste, pero a mi con la solución que te dieron no me vale, ya que implemento el código que te ofrecieron para arreglarlo y ahora me da un fallo de "Server Error" poniendo en usuario y password, los correspondientes a XI.
+Request_MI_outTurnoverDetailsDisplay_MI_outTurnoverDetailsDisplay req=new Request_MI_outTurnoverDetailsDisplay_MI_outTurnoverDetailsDisplay();
wdContext.nodeRequest_MI_outTurnoverDetailsDisplay_MI_outTurnoverDetailsDisplay().bind(req);
req._setUser("username");

No sé si es que ese usuario y contraseña son otros distintos.
Si pudieras ayudarme, te lo agradecería.
Un saludo, Luis

Calling a Report Program from Web Dynpro

Hi all,
I have a requirement, where i have to call a report program from web dynpro?. Wether its possible to call a report program in web dynpro?. Is we can call it, how this functionality has to be achived?

Hello,
Yes it is possible to call report using SUBMIT statement from one of the method defined in COMPONENTCONTROLLER's method tab.
Once you define the method with SUBMIT statement then call that method with proper event.
Rest configuration will remain same for ABAP webdynpro.
Hope this helps.

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

SRM 7.0 find transparent table name from Web dynpro Component

Hi ,
I am trying to find the transparent table name from Web dynpro component dictionary structure. I am working in SRM 7.0. Please let me know how to find the transpartent table for a field.
Thanks,
Monica

hi,
your question is very unclear and does not relate to performance.
SRM uses webdynpro ABAP so the recommendation will not help.
Do you need a technical UI element?
Or the application table where the business data of an UI is stored???
If it is the later, then you can use the SQL trace, change to element you are interested in, and trace it. The table should appear in the trace in connection which an UPDATE command. Still a bit cimbersome.
