Displaying image from Webserver on to a Swing application

Question

Hi guys,
We're developing an application that is typically swing <-> servlet <-> database.We want to retrieve an image present on the server system through a servlet( which actually gets the path of the image stored in the database and returns that image file on the HDD of server system as a byte[ ]).
My problem is im reading the image from the byte[ ] on the swing client and creating a new .gif file on the client system but couldnt create its dimensions.hence not able to display it on my app.Plz help.Thx for ur consideration.
my code looks as -
//this is Swing client
try
String query="select imgpath from emp_img where eid=1";
URL u=new URL("http://127.0.0.1:8080/servlets-examples/servlet/ImgServ?query="+URLEncoder.encode (query));
URLConnection uc=u.openConnection();
ObjectInputStream ois=new ObjectInputStream(uc.getInputStream());
byte b[]=(byte[])ois.readObject();
System.out.println("b size= "+b.length);
FileOutputStream fos=new FileOutputStream("emp.gif");
fos.write(b);
Graphics g=EmpImg.getGraphics();     //EmpImg is JButton
EmpImg.setIcon(new ImageIcon("emp.gif","pic"));
EmpImg.updateUI();
catch()......
bye

neilAre sure that you've closed fos?
fos.close();Probably file is incomplete?
