uploading image in a server????

[yatibawri]

I have taken example from this link to upload an image to server-

http://www.java-forums.org/javaserve...e-jsp-how.html

it reads the image in chunks but after that an error is displayed as
java.io.IOException: error 10054 during TCP read

I want to know the reason why is it so???
Is there any problem with this code?

InputStream Imgis = getClass().getResourceAsStream(FILE);
			byte[] imgData = new byte[Imgis.available()];
			Imgis.read(imgData);

The error that is displayed is-

java.io.IOException: error 10054 during TCP read

It does not give me the response msg before that the connection is closed...
Plz plz plz plz plz help me...it will be greatly appreciated...

Hello,
Which kind of connection are u working with!? Web Services or HTTP connection?! This is not an error of the data reading (such as the code u put here). Could u please put here the code that opens and sends the data?!

			String message2 = "";
			message2 += CrLf + "--AaB03x--"+ CrLf;
			System.out.println("open os");
			os = conn.openOutputStream();
			
			System.out.println(message1);
			os.write(message1.getBytes());

			// SEND THE IMAGE
			int index = 0;
			int size = 1024;
			do {

					size = imgData.length - index;
				}
				os.write(imgData, index, size);
				index += size;
				progress(imgData.length, index); // update the progress bar.

			} while (index < imgData.length);
			System.out.println("written:" + index);
            System.out.println(message2);
			os.write(message2.getBytes());
			
			os.flush();
			
			System.out.println("open is");
	
			long len=conn.getLength();
			byte[] data = new byte[512];
			is = conn.openInputStream();
			do {
				System.out.println("READ");
				len = is.read(data);
				if (len > 0) {
					System.out.println(new String());
				}
			} while (len > 0);
			os.write(data, 0, 512);
		

			System.out.println("DONE");

	    }catch(IOException e){
	       e.printStackTrace();
	    }finally{
	       System.out.println("Close connection");
	        try{

	        }catch(Exception e){}
	        try{
	            conn.close();           
	        }catch(Exception e){}
	    }
		return res;
		
	   
	}

please help me with the solution...

Hi,

First of all you will need a Server side code to handle the data accordingly. I hope that would be ready. Does this problem happen everytime you try to upload the image or sometime only. Where exactly does the problem occur?

Otherwise, please try the code mentioned in the above link.

Hope that help you out.

ya,i do have a server side php code,which handles the image that is send to the server.
this problem happens everytime,i dont understand why it is so?

the code below is an interprrtation of the code that i have already mentioned in my last post.

			os.flush();
			
			System.out.println("open is");//from here it goes to the catch block without reading further
			char buff=512;
			int len=(int) conn.getLength();
			byte[] data = new byte[buff];
			is = conn.openDataInputStream();
			do {
				System.out.println("READ");
				System.out.println("length is:" +len);
				len = is.read(data);
				if (len > 0) {
					System.out.println(new String(data, 0, len));
				}
			} while (len > 0);
			os.write(data, 0, 512);

please help me with it....

Hi,

What are you trying to read there? The image uploading code is in the above try block I suppose. Just try to comment out that code and then try.

Hi,

Have you tested it on the real device? Which emulator are you using? I think you should go through the below URL, it suggests some ways of overcoming that. Try that, may be something might click for you.

Thanks for your prompt reply
But, sunil_bhambani123
i am still facing the same problem.
while i try to make the request to the server i am getting
"Response Code returned during POST is 200" through conn.getResponseCode();
which means connection is successful,but the image is not loaded,there is some problem with it.
In my server side code,there is a response msg "Connection Successful" but i am not getting the response back to my device.

Can you help me with it.

Hi,

You can also try the code from the below link. I have tested that code and it works absolutely fine. The server side code is in JSP/Servlet. Its upto you to modify that into PHP, but it works for me.

Hi,
Thanks a lot for your help.
Now i am getting a connection successful message from server to the device,
but my problem is with the length it is taking length as -1
It should not be -1.
So,plz can u tell me the reason why is it taking so???

plz help me with the 1st reply...
it will be of great help.

[yatibawri]

I am still stuck at the same problem that my image is not getting uploaded to the server.
Now i am trying this content transfer encoding as base 64 for the image as:

message1 += "Content-transfer-encoding: Base64" ;

so i am right in doing the above line?

private final String FILE = "/image.jpg";
byte[] imgData = FILE.getBytes();
How to convert this imgData into string....plz help
