Hi kavita,
               In Webdynpro u r using attribute of type Resource ,which is binded to FileUpload UI element. From this attribute, u get file in Input stream format which can be converted into byte array like this
byte fileData[] = null;
      try{
            InputStream fileIs = wdContext.currentFile().getFileData().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();
            bOut.close();
      } catch (Exception e) {
            wdComponentAPI.getMessageManager().reportSuccess(e.toString());
In webservice u can take a the byte array as input parameter where the uploaded file will be passed as byte array .
In DB u can store it as BLOB .
in case of any other doubt u can revert back to me.
regards
