Help with redirecting URL from Web Dynpro

Hi,
I have a question regarding how i can construct a URL where i would like to forward the user from a WD app based on some user interaction.
The problem is that i need to know the protocol, server & host to resend the control to ( basically append these values to a url path that i have eg: <http(s)>://<host>:<port>/<the path i have>). With NW2004s, the request object is not exposed to us anymore, so i am wondering what is the best way to construct the url.
I have gone through various posts here and the one that came closest to accomplishing what i need is the one by Valery S which recommends creating a Servlet that captures the request info that i need and then calling the WD app including the info that i need as request parameters in the calling URL.
Before i do this, i want to see if anyone has been able to solve this through another approach.
Appreciate the inputs.
Best Regards
Renchy Thomas

Renchy,
Now I see you are conflicting with yourself
On one hand, if you need to redirect to the application hosted on the same server you need no protocol/server/port parameters. And you confirmed that this works for you.
On other hand, you are complaining that WD doesn't know in advance the protocol/host/port of arbitrary server you are planning to redirect to. Well, as I understand this is not API issue, this is configuration issue. You just need some configurable way to store such settings.
If this is true, then I can suggest 2 options:
1. HTTPDestination -- you are setting and configuring destination via VisualAdministrator, then from your code you are lookup destinitation by logical name and get physical URL.
2. IWDConfiguration / WDConfiguration -- you are creating settings as regular properties file, after deployment you may tweak this property file with VisualAdministrator. From code you are using WDConfiguration API to read URL or parts of URL as properties.

HTTP form post from Web Dynpro Java Application without opening new window

Hi Experts,
We are trying to submit form data to an external URL from Web Dynpro Java application. We are achieving this with the following piece of code.
try
   strPrintContent="<html>"+
     "<head>"+
     "<script type=\"text/javascript\">"+
     "function myfunc () "+
     "{"+
     "var frm = document.getElementById(\"paymentForm\");"+
     "frm.submit();"+
     "}"+
     "</script>"+
     "</head>"+
     "<body onLoad=myfunc()>"+
     "<form id=paymentForm method=post action=\""+merchantURLPart+"\">"+
     "<INPUT type=hidden name=username value="+userName+">"+
     "<INPUT type=hidden name=pass value="+passWord+">"+
     "<INPUT type=hidden name=senderid value="+senderID+">"+
     "<INPUT type=hidden name=dest_mobileno value="+mobile+">"+
     "<INPUT type=hidden name=message value='"+msg+"'>"+
     "<INPUT type=hidden name=response value="+response+">"+
     "</form>"+
     "</body>"+
     "</html>";
IWDWebResource webResource = WDWebResource.getWebResource(strPrintContent.getBytes(),WDWebResourceType.HTML);
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(webResource.getAbsoluteURL(),"WBSEDCL");
window.show();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException("Error : "+e.toString(),false);
But it opens another window. We dont need that. We have to stay on the same window. Please suggest what can be done.

Hi,
You can create a HTML file with the request post parameters and the external URL something like this:
public java.lang.String GetRedirecturl( )
// External URL
String html = "<html><head></head><body onload=\"load()\"> " +
"<form id=\"form1\" action=\"https://www.abc.com/xyz.jsp\" method=\"POST\">" +
// Post Parameters
"<INPUT TYPE=\"HIDDEN\" NAME=\"Param1\"VALUE=\""+Param1Value+"\">"+
"<input name=\"sap-wd-resumeurl\" type=\"hidden\"/>" +
"</form> " +
"" +
"<script>" +
"function load(){" +
"var loc = window.location.search.substring(1);" +
"var queryString = loc.split(\"sap-wd-resumeurl=\");" +
"if(queryString.length > 0)" +
"{" +
"var resumeURL = queryString[1].split(\"&\");" +
"if(resumeURL.length >= 0)" +
"{" +
" document.forms['form1'].elements['sap-wd-resumeurl'].value= unescape(resumeURL[0])" +
"}" +
"}" +
"document.getElementById('form1').submit();" +
"}" +
"</script>" +
"</body> </html>";
String redirectUrl = "";
byte[] byteArrayHtmlData = null;
try {
byteArrayHtmlData = html.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
wdComponentAPI.getMessageManager().reportException("Internal error occurred. Please try after some time",true);
IWDResource htmlResource = WDResourceFactory.createCachedResource(new ByteArrayInputStream(byteArrayHtmlData), "Redirect.html", WDWebResourceType.HTML, true);
redirectUrl = htmlResource.getUrl(WDFileDownloadBehaviour.AUTO.ordinal());
return redirectUrl;
Hope this will be helpful.

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..

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

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.

CE 7.1 - How to call CAF services from Web Dynpro

Hi,
whats the suggested way to call caf services from web dynpro?
Of course I can use the Web Service model. But can I call caf directly?
I read something about caf web dynpro model, but I cannot find it in nwds 7.1. On some older tutorial it was in context menu of caf project, but it seems to be removed.
best regards
tom

Hi ,
The standard way is to use the web service model.
You have to expose the the services as web service and then you can use the wsdl url in the Adaptive web service model option.
The above option will be available when you click the Model in the webdynpro application and the click create new model.
Hope it helps you.

Navigate from Web Dynpro app to portal page

Dear All,
I've created a number of Web Dynpro applications which I run from various portal pages. From one of the Web Dynpro's I navigate to a different portal page using the WDPortalNavigation.navigateAbsolute method. This works fine, but I'm left with one problem:
I'd like to pass parameters from the Web Dynpro which navigates to the portal page to the Web Dynpro applications which run on that specific page. I've appended the parameters to the URL I'm navigating to (eg ROLES://<pcd location>?<param=xxx>) and in the Web Dynpro's I've added a parameter to the Default interface plug. This doesn't seem to work. As an alternative I've added the statement WDWebContextAdapter.getWebContextAdapter().getRequestParameter("param") to the doInit() method of the view, but this also doesn't work.
Either I'm doing something wrong, or what I want to accomplish is not possible. Does anybody know of a way to access parameters passed to a portal page from Web Dynpro applications contained on that page?
Thanks,
Arnoud

I hope you are passing parameters between two WebDynpro applications.
Please go through the example available for passing interaction between two webdynpro components.
Please check the following link
Alternative method for navigating to another page ?

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.

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.

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.
