File Visibility in uploading the file using web DynPro java

hello,
i have gone through the tutorial " uploading & downloading the file using web DynPro java".
the upload functionalty is working fine. but i need to know thw path where these files are getting uploaded ??
Waiting for the reply..
Regards,
Viren Gupta

Hi Viren,
Are you are refering to the below tutorial for upload and download:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b0e10426-77ca-2910-7eb5-d7d8982cb83f?QuickLink=index&overridelayout=true
If yes, then answer is that the file is stored in the context of the application only as "com.sap.ide.webdynpro.uielement-definitions.Resource" object. Please read through the tutorial to understand the full process.
WD doesn't really upload to server automatically unless there is any explicit code written. All it does is to store the file in a temp context which you can access and write your own code to store it in a particular location.

How to create a user in UME Database using web dynpro java custom application

Hi,
Can you please suggest me how to create a user in UME Database using web dynpro java custom application.
My Requirement is user can register his/her user id in SAP Portal 7.3 UME database.
Please suggest me.
Thanks and Regards,
Amit

Hi Amit,
Generated Documentation (Untitled)
This is what you're looking for, there's no real cook-book -- though Amey mentioned there might be some material on SDN, perhaps some tutorials.
You should be looking into com.sap.security.api.IUserFactory, methods newUser(String) which gives you and IUserMaint and commitUser(IUserMaint, IUserAccount) -- IUserAccount can be obtained using com.sap.security.api.IUserAccountFactory, method newUserAccount(String)
Hope it helps,

Problem in completing the TASK when using Web Dynpro Java and BPM

Hi,
I am using Web Dynpro Java and BPM.
i see my Web Dynpro View when i run the process.
Just that the task is not completing.
when i click on the Web Dynpro button to signal the completion of the event, nothing happens.
i have appropriately created events in both Component controller and Interface Controller and used the same in creating the Task.
a method in Component controller fires the event and a button click in the view calls this method.
i have successfully completed Donka Dimitrova's "SAP Netweaver Business Process Management-End-to-End Process Implementation Sample " but when i tried my own with slight modifications, it is not working !!!

Hi Amol,
The way you described the things, I dont see any problems. Just to make sure that you are triggering the right event that you mapped as completion event for the task, try to cross check once again and see if the correct event is getting triggered. Also try to put some messages for debugging to see till where the control goes.

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks

How to use Web Dynpro Java isChanged and isChangedByClient

Hello,
I have read thorugh a lot of documentation, threads, ... --> but the picture is not geting clearer fro me.
We have Web Dynpro Java Application (on Netweaver 7.0 SP12) running in Enterprise Portal. We need to tell the portal work protect mode, that we have unsaved changes (how to do this is clear).
I am struggling with figuring out, that my Web Dynpro Context has unsaved changes. I found the two change-indicators isChanged() and isChangedByClient(), which already confuses me a little bit.
Anyway, this is what I have figured out so far:
I am calling wdContext.currentContextElement().isChangedByClient() to figure out changes and when a Save operation has been completed sucessfully, I call wdContext.currentContextElement().node().getContext().resetChangedByClient(). This works for some of the changes made by the user.
I then tried calling wdContext.nodeABC().getElementAt(i).isChanged() for all nodes of my Web Dynpro Context, but this results in detecting changes before the user ha done any interaction.
Implementing an own change tracking (i.e. by adding a changed-Attribute to each context node) does not seem a viable option for me.
So these are my questions:
- Does anyone now a working pattern relying on those chnage indicators ?
- Does anyone now how to reset the isChanged indicator (or when it is resetted by the framework) ?
Any help appreciated.
Thank you,
Stefan

Accessing a R/3 Workflow workitem directly using Web Dynpro Java/ABAP

Hi,
I have a requirement for which I am not sure what will be the correct forum to post. But I guess it involves Portal / Web Dynpro so I started from here.
You can guide me to correct path as we move forward.
Current Scenario:-
There is a work-flow prepared in SAP R/3 system which triggers a mail to user with a link to Portal UWL. In UWL, user may select the task and click on it to execute.
Scenario to be developed:-
Instead of link in email to UWL, link should directly navigate to work-item in Work-flow.
Any idea how this can be done?
Thanks and regards,
Amey Mogare

Uploading & Downloading Files into DMS Server using Web Dynpro Java

Hello Friends,
      I want to Upload a file from Portal to Document Management Server and to Download a file from Document Management Server to Portal, In short, I want to give the user the facility to Upload a File into DMS Sever via Portal and also to download the file from DMS Sever via Portal.
Can anybody give me a Input for the same from Both Java Development End as well as ABAP End, more inputs are required from ABAP end, since i have a very less ABAP Experience on working with DMS. Few Questions i have in my mind?
1. How to actually access the file contents with the help of Document Number?
2. With the help of Doc-Number we can extract the file from DMS sever but to provide a option for downloading in portal, the   RFC should convert the File Contents into X-String or is there some other way?
+3. While Uploading the Data should be given in Which format to RFC? Are there any limitation with respect to size or formats. Is there any Standard RFC i can use directly in WD4 Java application to upload the file into DMS Server and which will return me the Document Number? +
Please give me your valuable inputs.
Thank You.

Generate Adobe Interactiveform pdf using Web Dynpro Java API.

I created pdf form by using standard "InteractiveFormElement" and it is displaying correctly in browser.
Now there is a requirement to provide url link to the same pdf that is displayed with InteractiveFormElement. To generate pdf, I was doing something the below.
//Copied XDP file from the srcconfigurationcomponents<package><file>.xdp
//to srcmimiescomponents<package><file>.xdp
try {
     templateUrl = WDURLGenerator.getWebResourceURL(
                               wdComponentAPI.getDeployableObjectPart(),
                      "CompView_InteractiveForm.xdp");
} catch (WDURLException e) {
IWDPDFDocumentCreationContext pdfContext =
   WDPDFDocumentFactory.getDocumentHandler().getDocumentCreationContext();
pdfContext.setData(
   WDInteractiveFormHelper.getContextDataAsStream(wdContext.nodeDataNode()));
pdfContext.setTemplate(templateUrl);
IWDPDFDocument pdf = null;
try {
     pdf = pdfContext.execute();
} catch (WDPDFDocumentRenderException e) {
               wdComponentAPI.getMessageManager().reportException(
"pdfContext.execute() " + e.getLocalizedMessage(), false);
IWDPDFDocument.execute() is raising exeception "Template used in PDF render
operation is invalid or cannot be found". template url is indeed correct. I checked by
assigning to that url to linkToUrl Element and opening the xdp file.
Please help me to identify the issue. Thank you.

Hi Ajay,
Use getResourcePath instead of getWebResourceURL
templateUrl = WDURLGenerator.getResourcePath(
                               wdComponentAPI.getDeployableObjectPart(),
                      "CompView_InteractiveForm.xdp");
Thanks

Dynamic role Assignment in Portal using Web dynpro Java?

Hi All,
We have following requirement for dynamic role assignment.
1) User Login to Portal.
2) User Clicks on Home Tab in Portal, through RFC/BAPI, get Role from Backend(ECC) and compare the role ID with Portal Object ID through UME.
Role gets assigned in Portal after comparison, if it exists in Portal.
Can you please let me know what all steps I need to do to complete the above assignment.
Thank you
Ravi

Thanks Tobias.
To be precise I will explian my requirement.
1) User Login ( User ID will be input to RFC)
2) RFC will get Role for that user ID from Backend(ECC) and return that role ID to Portal.
3) Now With the help of UME API, need to search role ID in Portal, If it exists, no action.
If Role ID does not exists, then it shuld assign that role in Portal.
Sorry for tedious comment.
I am a bit new to webdyn pro.
Can you please tell me each step i need to follow to complete the above requirement.
Many Thanks,
Ravi
