Two methods of transporting file in webservice

First Method,

endpoint code

  public String echoBinaryAsString(byte[] bytes,String filename) {
	  String filePath = "c:/softs/img/"+filename;
      
      try {
          FileOutputStream fos = new FileOutputStream(filePath);
          BufferedOutputStream outputStream = new BufferedOutputStream(fos);
          outputStream.write(bytes);
          outputStream.close();
           
          System.out.println("Received file: " + filePath);
           
      } catch (IOException ex) {
          System.err.println(ex);
          throw new WebServiceException(ex);
      }
	    return new String(bytes);

	  }

Endpoint code

// Use @XmlMimeType to map to DataHandler on the client side
	   public void fileUpload(String fileName,@XmlMimeType("application/octet-stream") 
	                          DataHandler data) {
		   String filePath = "c:/softs/img/"+fileName;
		   InputStream is;
		  
		try {
			is = data.getInputStream();
			File file =new File(filePath);// File.createTempFile(filePath,"");
			   OutputStream os = new FileOutputStream(file.getAbsolutePath());
			   System.out.println(data.getName()+","+ data.getContentType()+","+file.getAbsolutePath());
			   byte[] buffer = new byte[1024];
			   int bytesRead;
			   while ((bytesRead = is.read(buffer)) != -1)
			   {
				   //System.out.println(bytesRead);
			       os.write(buffer,bytesRead);
			   }
			   os.flush();
			   os.close();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} // DataHandler
		   
	  }
