Issue in decompressing bytes

[jeet232]

I'm sending 56kb of GZipped data from sending side over a socket on localhost. The receiving side (at localhost) receives it and needs to unzip it. I receive: EOFException: Unexpected end of ZLib input stream

Sender:

ByteArrayOutputStream b = new ByteArrayOutputStream();
GZIPOutputStream g = new GZIPOutputStream(b);
b.write(bData); /* bData is a byte array of 500k bytes size*/
byte[] bData2 = b.toByteArray();
g.close();
b.close();

BufferedOutputStream bos = new BufferedOutputStream(socketObj.getOutputStream());
bos.write(bData2); 
bos.flush();       
bos.close();

Receiver:

DataInputStream d = new DataInputStream(socketObj.getInputStream());
ByteArrayOutputStream b = new ByteArrayOutputStream();
 
int iRead = -1;
while((iRead = d.read()) != -1)
    b.write(iRead);
 
return b.toByteArray();

Data is received properly with same no. of bytes but when i try to decompress it, I receive the above mentioned exception. Here is the code for decompressing.

ByteArrayInputStream b = new ByteArrayInputStream(bData);
GZIPInputStream g = new GZIPInputStream(b);

Here bData contains the compressed bytes. At this point the exception is raised.


Please give some suggestion why the decompression is not working. I'm using JDK1.5

@jeet232
You never zip anything, i.e. you're using the wrapped OutputStream directly without using the write() method of the GZIPOutputStream. The bytes are written as is and no decompression is possible on them (in the receiver).

kind regards,
