Compression/ uncompression issue over sokects

Question

Only one thread running at the time of test;
JAVA: Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
i have a problem with the following scenario.
A client inside a loop reads data from a file, does some processing of incoming data, compresses it and sends it
to the server over a socket. The server at the first instance of the read throws: *"java.util.zip.ZipException: invalid distance too far back"*
The Client side compressiion code snippet is:
==================================
try{
Deflater defltr = new Deflater(Deflater.DEFAULT_COMPRESSION, true);
DeflaterOutputStream deflOpStrm = new DeflaterOutputStream(new BufferedOutputStream(
     thrdHlpr.getClntSkt().getOutputStream()), defltr, BUF_SIZE); //BUF_SIZE= 10240 .....1024/512
DataOutputStream opStrm = new DataOutputStream(deflOpStrm);
while(!isInterrupted()) {
while(true){
while(0 != chBufLen && -1 != chBufLen){
char[] chBuff = new char[BUF_SIZE]; //BUF_SIZE= 10240 .....1024/512
chBufLen = inFile.read(chBuff, 0, BUF_SIZE);
if( 0 < chBufLen){
offset += chBufLen;
rawBuf.append(chBuff, 0, chBufLen);
//Do my things with the data and transfer data to outBuf
opStrm.writeUTF(outBuf.toString());
deflOpStrm.flush();
opStrm.flush();
//I have tried with and without calling finish & reset
//deflOpStrm.finish();
//defltr.reset();
chBuff = null;
}//end while(0 != chBufLen &&.....
}//end while(!isInterrupted
//Catch block.....
Server side UncompressCode is:
======================================
try{
Inflater infltr = new Inflater(true);
InflaterInputStream infInputStrm = new InflaterInputStream(clntSokt.getInputStream(), infltr, BUF_SIZE/2);
DataInputStream dInptStrm = new DataInputStream(infInputStrm);
while(true) {
String result = dInptStrm.readUTF(); //Exception is thrown here
output.seek(output.length());
output.writeUTF(result);
//Have tried with and without reset.
//infltr.reset();
}//end while(true....
//catch block
The Satk is:
=============================
java.util.zip.ZipException: invalid distance too far back
     at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:164)
     at java.io.DataInputStream.readFully(DataInputStream.java:195)
     at java.io.DataInputStream.readUTF(DataInputStream.java:609)
     at java.io.DataInputStream.readUTF(DataInputStream.java:564)
Since i have tried this many different ways..... i most appreciate time and effort of those who have a difinite answer to take a shot at it.
Thanks very much for your time and answer.

please don't double post
