Hi Sathya,
         I guess you are trying to upload data from excel file(XLS format).
         If it is correct then you cannot do this in webdynpro, first you save the excel file as tab delimited.
         Open your excel file->save as->other formats->give file type as TEXT(Tab delemited).
         Now use this file to upload. It should work perfectly.

Newbie : memory problem with file uploading

Hello
I'm exdending a web app based on jsf and , being new to it and java in general, i'm having a problem with file uploading.
The customer needs to upload large file (more than 30 MB). The application accomplish this using a fileupload component, to let the user select the file, and passing the array of bytes to a web service method.
I'm using netbeans 6, tomcat 5.5.
When i try to upload a file too large i got an outofmemory on the local tomcat. So i've rised jvm memory and going on with tests i've found that growing the size i got an http 500 error from the service (the developer of the service has found an out of memory too ).
I think the service is not modifiable, so i were asking if threre were a way to optimize the file uploading process (a component, a library, a pattern ...) or my only chioice is to rise available memory on both sides.
I've notice the wsdl declares as base64binary type the data parameter , while netbeans 6 generates a client proxy with a byte[] parameter. Is correct or is a netbeans problem?
searching with google i've found few thing i haven't fully understood due to my lack of experience:
the mtom , how can evaluate if it's suitable to help in my problem (i suppose it involves more the web service rather than the client)
something about the size of a soap body.
thank you in advance
Stefano

Which component exactly are you using? Declaring the stream as a raw byte[] is certainly not efficient. Write code yourself, don't let it autogenerate.
I can highly recommend you the Tomahawk t:inputFileUpload component. It is easy to integrate in Mojarra. You can find here an useful article: [http://balusc.blogspot.com/2008/02/uploading-files-with-jsf.html].

I remember that there was a bug in the MultipartHandler of the BC4JRequestProcessor in one of the 10.1.2.x version, however I'm nit sure which one. I found the old fix we implemented back then
Try this request processor and see if this helps:

        // Overide only if the action mapping is a BC4JActionMapping.
        BC4JActionMapping mapping = (BC4JActionMapping) request.getAttribute(Globals.MAPPING_KEY);
        if (HtmlServices.isMultipartPost(request)) {
            MultipartRequestHandler handler = MultipartUtil.retrieveMultipartHandler(request);
            if (handler == null) {
                try {
                    request = MultipartUtil.parseMultipartRequest(request, servlet);
                catch (ServletException se) {
                    throw new RuntimeException(se.getMessage());
            else {
                // This is a forward from a Multipart Post upload
                if (!(request instanceof MultipartRequestWrapper)) {
                    request = new MultipartRequestWrapper(request);
                    MultipartUtil.setWrapperParams(handler, (MultipartRequestWrapper) request);
                else {
                    // do nothing
        return (request);
Don't forget to set this new class in your struts-config.xml file!

How to Save a file uploaded in WebDynpro Java to Windows server

Hi Guys,
I need to save a file uploaded in WebDynpro Java to a location on one of my companys many internal Window servers but I cannot get it to work. I do not get any errors with the following code, but NOTHING happens... And when I check the folder it is still emply... Please advise. I am particularly not sure about specifying the Path syntax. Also, I do have permission to write to this server. Is it even possible to save to a Windows server from WebDynpro??
//uploaded document already in context...
byte[] file = element.getFileResource();
            //    get the size of the uploaded file
            element.setFileSize(this.getFileSize(file));
            wdContext.currentContextElement().setFSize(this.getFSize(file));
            //    get the extension of the uploaded file
            element.setFileExtension(binaryType.getMimeType().getFileExtension());
            String fName = wdContext.currentContextElement().getFName();
            String fExt = wdContext.currentContextElement().getFileExtension();
            String foName1 = "
server01.w9\Files\P
HRP_Attachments\" + fName + ".pdf";
            File f1 = new File(foName1);
            DataOutputStream dos1;
            dos1 = new DataOutputStream(new FileOutputStream(f1));
            dos1.write(file);
            dos1.flush();
            dos1.close();
Edited by: christiaanp on Sep 30, 2011 8:07 AM

Hi Christiaan,
When specifying the path, make sure you escape the slashes
So, when you would normally use something like
\\server\path\file.txt
in your code you must use it in the form:
String fileName = "\\\\server\\path\\file.txt";
Hope this helps!

Pb with file upload.

          Hello,
          we do have a problem with file upload ! We're using the o'reilly class, but every
          time we add ENCTYPE="multipart/formdata" in the html, we're unable to correctly get
          the request. ?
          any idea ? Is there something to configure ?
          thx


          The request is in the form of multipart data and is parsed by the
          Oreilly class only. To access other information from the request
          the Oreilly class has provided you with the methods for getting
          the other data. You have to access the data from the request using
          the Oreilly class methods

Problem with file upload

Hi all, my problem has something to do with internal working of pageflow.
Here is what has happened:
1. I have a page with a few portlets on it.
2. One of the portlet is for uploading file (lets call it upload portlet)
3. The rest of the portlet need to access the PortletBackingContext using the following code (put in a jpf):
PortletBackingContext portletCtx = PortletBackingContext.getPortletBackingContext(super.getRequest());
4. When the upload portlet transfers the file, the other portlets will refresh (i'm using refreshAction attribute).When the other portlets refresh, they can't get the PortletBackingContext. It always returns null.
If I remove the enctype="multipart/form-data" from the netui:form tag, it works as per normal (but of course the file uploading fails).
Any idea?
Thanks.

Problems with file upload using AMF or SOAP

We use your AMF to connect Flex with Ruby on Rails.
Everything is OK, except file upload.
We did not find how to upload file using AMF or SOAP RPC from
Flex. Only to use FileReference.upload().
The problem is that Flex uses different User-Agent in HTTP
header for this upload and for SOAP/AMF calls.
This means that sessions are different. And even if you
authenticated via SOAP/AMF you can not use it to upload file.
Could you, please, advice is there any other way to upload
files from Flex via SOAP or AMF?

Please, help me on this issue, i am still waiting for someone replying me!

Problem with File Uploads

Hello all. Has anybody successfully got the UploadFilter classes -- as listed in Hortsmann and Geary's "Core JSF" -- going?
Everytime I submit a multipart form, I am not redirected to the appropriate next page (as specified in the navigation cases) . I have definitely set up the UploadFilter correctly, and any multipart form requests are getting parsed and uploaded into the correct directory. The only problem is that the resulting page isn't the one specified in faces-config.xml -- it's the original upload page.
If I get rid of the multipart/form-data encoding for the form, it works "okay" (in the sense that the file upload no longer works, but the behaviour matches the navigation cases).
I'm beginning to wonder whether the fact the form is a multipart form means that the submit button's action -- which is set to "submit", matching a value in faces-config.xml -- isn't being correctly parsed. Are there any "gotchas" I should be aware of in these cirumstances?

Hi diritchie,
perhaps that thread helps you.
http://forum.java.sun.com/thread.jsp?forum=427&thread=473135
There are posts of some clazzes, to enable upload.
the clazzes are using Jakarta Commons FileUpload
btw. in MyFaces there is allready an upload-component.

File Upload Using WebDynpro

Hi All,
I want to upload single or multiple CSV files using a user interface written in WebDynpros. The files will then be parsed and converted to XML.
I did something similar with jsps earlier but am not sure how to go about it with WebDynpros.
If anyone has already done something similar then please share your views.
Thanks in advance.

Issues with file upload in flex mobile application (sharepoint as backend)

Hello,
I am working on flex mobile application for android platform for which we are having sharepoint as a backend.
(Flex SDK 4.6 and AIR 3.9)
Issue which we are facing is as follows:
We are communicating with the backend server using webservices: example:
<s:WebService id="kWebService" wsdl="http://www.kservice.net/kdatabaseservice.asmx?WSDL" >
            <s:operation name="AddPost"
                         resultFormat="object"
                         result="addPostResult(event)"
                         fault="postsfaulterr(event)" />
</s:WebService>
Above services are working fine but we are facing issue with one service which is related to file upload.
File upload for <10 MB is working fine but when we try to upload larger file on server it fails to process.
We are sending bytearray to the backend and backend code is writing those bytearray into file.
We have tried many ways to overcome from this situation. like we have checked configuration for file upload size on server , we have tried wcf services as well. Please help us on this criticle point as soon as possible
Thanks

What do you mean that my video saves the contents int he server and not in transparent table? I save the data into a temporary database table so it can be accessed by the parent WDA session. From there the WDA session can do whatever it wants with it. What do you mean by transparent table - that would be a database table. Do you actually mean internal table? if so, just read the data from the temporary database table into memory.

Flat File Upload from WebDynpro ABAP

Hi,
I am struggling to find a solution for this requirement and I hope I get some help from the Gurus here.
I have to upload a ".csv" file from the WebDynpro application, and then store the data in the flat file in a Z# table.
Can some one explain me how to go ahead with this requirement??

Hi Nrisimhanadh Yandamuri ,
After reading the csv file using file up load you can use the following code to tranfer the same to an itab of your required format
    DATA : loc_conv TYPE REF TO cl_abap_conv_in_ce,
      var_string TYPE string.

      RECEIVING
        conv        = loc_conv.
*Read the file contents
    TRY.
        CALL METHOD loc_conv->read
          IMPORTING
            data = var_string.
