InputStream Problem at Client Side.

[pavan aryan]

Hi all once again, one more question from me. But this one stands between me and my final work. I am doing a REST Webservice, in which I have to send image files from the server and had to calculate processing times at the client. So, I choosen InputStream at the server, and same to catch at the Client. Seems some basic problem, I am measuring time before and after InputStream at Client..seems since its a stream as soon as receiving some bytes the program was coming to the next....better to put it in code... REST Web Service and i am using Netbeans 6.8

Server COde

@Path("/restserver/image23")
public class imagetest23 {
    @Context
    private UriInfo context;

    /** Creates a new instance of imagetest1 */
    public imagetest23() {
    }


  @GET
 @Path("{id}")
//@Produces ("StreamingOutput/text")

public InputStream GettheFile(@PathParam ("id") String cId) throws Exception



    {


      File file =  new File("C:/"+cId+".png");
     InputStream in = null;

      //File file =  new File("C:/fone.gif");
      FileInputStream fs = new FileInputStream(file);
        //   int cid=01;
in = new BufferedInputStream(new FileInputStream(file));
         
        return in;




    }
}

And at the Client Side

private static void testgettingfiles() throws IOException, WebApplicationException, HttpException, java.sql.SQLException,java.lang.ClassNotFoundException, com.sun.jersey.api.client.UniformInterfaceException {

System.out.println("coming to here, start of the getmethod in client");


            final String BASE_URI = "http://xxxxx:8080/RestApplication-Server/resources";
           System.out.println("the value of string"+BASE_URI);
            System.out.println("coming to here before start of client");
    Client c = Client.create();
    WebResource service = c.resource(BASE_URI);

    System.out.println("coming to here after baseuri");
    System.out.println("the time before fetching starts:");
long g= System.currentTimeMillis();


InputStream in=service.path("/restserver/image12").get(InputStream.class);

long f=System.currentTimeMillis();

System.out.println("the total time :"+(f-g));

}

So thats the problem ..no matter the size of the image files (trying from 5 mb to 50mb) the processing time is just few milli seconds and almost the same..


tried a bit logic to convert the files

BufferedImage bi1 = ImageIO.read(in);
System.out.println("the time after fetching");
long f=System.currentTimeMillis();
File file = new File("newimage1.png");//(dint changed)changing to .gif
ImageIO.write(bi1, "png", file);//(dint changed)changing to .gif
 FileInputStream fs = new FileInputStream(file);

But getting different size files...and if i take the time here, it also includes conversion and saving file locally times....Since its REST and i test with a plane url and its returning same files size ( tried right click and save as )...

Thanks in advance guys,...spent whole night on this..
