0 bytes resource

Question

Hi there,
I'm trying to use FileUpload component with no sucess. No matter what I do I always get a 0-byte long resource (all other resource attributes are ok, such as resource name, mime type, and so forth). The resource.read(false) method always return an empty InputStream. Should I do something with the resource before it is populated with real bytes???
Best,
Ricardo

Hi,
I imported the SCA files and deployed the DC and it works fine for me.
            IPrivateUploadFileView.IContextElement element = wdContext.currentContextElement();
          IWDResource resource = element.getFile();
          byte fileData[] = null;
          // if a file in the FileUpload field exists
          if (resource != null) {
               try {
                    int fileLength = 0;
                    InputStream fileIs = resource.read(false);
                    ByteArrayOutputStream bOut = new ByteArrayOutputStream();
                    int length;
                    byte[] part = new byte[10 * 1024];
                    while ((length = fileIs.read(part)) != -1) {
                         bOut.write(part, 0, length);
                    fileIs.close();
                    fileData = bOut.toByteArray();
                    fileLength = fileData.length;
                    bOut.close();
                    wdComponentAPI.getMessageManager().reportSuccess("File Length"+fileLength);
                    if (fileData == null || fileLength == 0) {
                         throw new RuntimeException("File data is null or zero-byte");
               } catch (Exception e) {
                    wdComponentAPI.getMessageManager().reportException(e);
          } else {
               wdComponentAPI.getMessageManager().reportException("File not defined");
         wdThis.wdGetUploadFileComponentController().fireUploadFileCompletedEvent();
wdComponentAPI.getMessageManager().reportSuccess("File Length"+fileLength);
Is printing the size
Note:-1.There is no issue in ur component possible reason might be try uploading different files.
          2.Try reinstalling your NWDS and import the SCA then which could fix this issue.
