socket data compression problem

[bow huang]

dear everybody,
i hava a problem in socket data compression:
client:
socket = new Socket(host,4000);
ZipOutputStream zipout = new ZipOutputStream(socket.getOutputStream());
zipout.putNextEntry(new ZipEntry("a.zip"));
DataOutputStream output = new DataOutputStream(zipout);
DataInputStream input = new DataInputStream(socket.getInputStream());
output.writeLong(10000);
long clientNumber = input.readLong();//1234
output.writeInt(222);

server：
ServerSocket serversocket = new ServerSocket(4000);
Socket client = serversocket.accept();
ZipInputStream zipin = new ZipInputStream(client.getInputStream());
zipin.getNextEntry();
input = new DataInputStream(zipin);
output = new DataOutputStream(client.getOutputStream());
output.writeInt(1234);
long magicNumber = input.readLong();//10000
int intnumber = input.readInt();//222
The app blocked when run to readLong() and readInt(),what's the problem?

Try calling output.flush() before attempting to read input.
