bzip using

P: n/a
I'm was planning on evaluating the use of bzip compression (instead of
the default java compression algorithms) for purposes of storage in a
database. So I grabbed the bzip libraries
( for this

The exmpales on the Jakarta website are limited to a usage pattern for
reading/writing to/from a file. Is it appropriate to use this API for
storage to/from a byte array (for storage in a DB)?

Here's what I'm trying...

public static ZipObject bZip(Serializable inObj) throws IOException {

ByteArrayOutputStream byteOut = new ByteArrayOutputStream();
ObjectOutputStream objOut = new ObjectOutputStream(byteOut);

byte[] dataArray = byteOut.toByteArray();
int origSize = dataArray.length;

ByteArrayOutputStream bZipByteOut = new ByteArrayOutputStream();
CBZip2OutputStream bZipOut = new CBZip2OutputStream(bZipByteOut);

bZipOut.write(dataArray, 0, dataArray.length);
byte[] compressedDataArray = bZipByteOut.toByteArray();

....but the output is eratic and can never be decmopressed (but am able
to save the byte array to a database).

Am I doing something foolishly wrong?
