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.

Mahesh

Overwriting a File in the KM using web dynpro

Hello,

Hi,
first check, if the resource exists, then decide to create or update content:
    IResource resource = (ResourceFactory.getInstance().getResource(rid, ctx));
    ICollection aCollection=(ICollection)resource;
    // get new resource RID
    RID newResRid = RID.getRID(repository+RID.PATH_SEPARATOR+resourceName);
    // try to find the resource
    IResource newResource = (ResourceFactory.getInstance().getResource(newResRid, ctx));
    if(newResource!=null) {
      // does exist - update content
      newResource.updateContent(content);
    else {
      // does not exist - create
      newResource = aCollection.createResource(resourceName, null, content);
Hope that helps,

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUpload(ServerEvent)
    IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
             IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
    IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
             getModifiableSimpleType();
    IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
    String fname = binaryType.getFileName();
    wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
     try {
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    // Statement 2
          InputStream in = new FileInputStream(fname);
          HSSFWorkbook wb = new HSSFWorkbook(in);
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    //Statement 3
          int sheetsNo = wb.getNumberOfSheets();
          for (int i=0;i<sheetsNo;i++) {
               HSSFSheet sheet = wb.getSheetAt(i);
               Iterator rowsNo = sheet.rowIterator();
               while(rowsNo.hasNext()) {
                    HSSFRow rows = (HSSFRow)rowsNo.next();
                    Iterator colsNo = rows.cellIterator();
                    while(colsNo.hasNext()) {
                         HSSFCell cell = (HSSFCell)colsNo.next();
                         wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
                              "successfully");
                         if(cell.getCellType()==1) {
                              wdComponentAPI.getMessageManager().reportSuccess("00000"+
                                   cell.getStringCellValue());
                         else if(cell.getCellType()==0) {
                              String str=""+cell.getNumericCellValue();
                              wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
     catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

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

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)

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

Upload File in Web Dynpro Java CO and store it in the context

Hi Guys!
I have developed a web dynpro CO form, and I need to be able to upload a file in an action and then be able to download that file in further actions.. I have evaluated saving the file in the backend via RFC, in KM and also creating a CAF project.. but I think there must be a simpler way : saving it in the context of GP.
Does someone knows if it is possible to do that?
best regards,
Marco.

Hi Marco
In webdynpro java, there are UI elements File Upload and File Download. You can use these UI's to upload and download attachments. From NetWeaver 7.0 onwards, you have IWDResource interface which can be used to upload attachments. But in GP if you want to pass attachment to another action you must use Binary as a data source. Bind the File upload UI element to Binary. In addition, you should define input and out parameters in getDescription method.
Thanks

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.

The above is the RFC Code, I am using in my WD4Java app for downloading the file From DMS Server, Is there any Improvement suggested for above RFC to make it work in more efficient way. Please give me input for my Upload RFC.
Thank You.
