Java Programming

hi all
i'm having a problem in socket programming. well, through the code, i'm trying to download a file...and at the end of the download i get the following error:

java.net.SocketException: socket closed
java.io.EOFException
    at java.io.ObjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2502)
    at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1267)
    at java.io.ObjectInputStream.readObject(ObjectInputStream.java:339)
    at beans.downloadingThread.run(Download.java:79)

java.net.SocketException: socket closed

the code is as follows:

try {
//set up our connection
connect = new Socket (ipAddy, 1000);
ObjectOutputStream outclient = new ObjectOutputStream(connect.getOutputStream());
ObjectInputStream infrom = new ObjectInputStream(connect.getInputStream());
//write the objects of stuff to get to the server
outclient.writeObject(fileGet);
//set our progress bars minimum
progress.setMinimum(0);
//setup the progress bars maximum
progress.setMaximum(Integer.parseInt(size.toString()));
//start the while loop
while (true) {
//setup the get varible to read from the server
Object get = infrom.readObject();
//switch the flag so our in from server can have some sense made of them
switch (flag) 
{
//case 0 is our main case this is when things get triggered 
case 0:
	//see if we got a start download;
	if (get.equals(".startdownload")) 
	flag = 1;
case 1:
	//our in is the same as our out BUT we have to read from the stream byte by byte
	int data;
	int totalDataRead;
	int totalSizeWritten = 0;
	int totalSizeRead;
	int PACKET_SIZE=125;
	byte[] packet=new byte[PACKET_SIZE];
	try{
		String currentDirectory = System.getProperty("user.dir");
		String uploaddirectory = currentDirectory + "\\share1\\"+fileGet;
		FileOutputStream fos = new FileOutputStream(uploaddirectory);
		long file_size=Integer.parseInt(size.toString());
		long no_of_packet=file_size/125;					
		int last_psize=(int)(file_size-(no_of_packet*125));
		while((totalDataRead = infrom.read(packet,0,packet.length)) >-1) {
        		fos.write(packet,0,totalDataRead);
    			totalSizeWritten = totalSizeWritten + totalDataRead;
    			progress.setValue(totalSizeWritten);
	        }
        }
}
catch(Exception x){
System.err.println(x);
x.printStackTrace();
}
flag = 0;	
}fos.close();
}
} catch (Exception e) {
System.err.println(e);
e.printStackTrace();
}                 

i've checked the downloaded file and the file is downloaded completely and properly. but still by the end of the download process it indefinitely prints the error

java.net.SocketException: socket closed

Please, help!
Its URGENT.
Thanks
