Thanks Brad,
I knew this and this is what I referred to as hiding something under the carpet. I'd use this as the last resort since I'm afraid that my file sizes may start creeping larger and I don't notice that early enough. Perhaps I wasn't clear in my mail. (I'm not sure if I'm clear enough now :) I'd like to ensure that only absolutely necessary things get serialized.
Anyway I'd like to be able to compress the images also when they are in the working memory and zipping of the serialized file doesn't help in that.
Thanks anyway.
Pasi

Hi,
I am not sure how this fits in with what you want, but you can compress the results of object serilization. Just wrap your
ObjectOutputStream in a zip or gzip output stream.
eg
ByteArrayOutputStream baos = new ByteArrayOutputStream();
GZIPOutputStream gzos = new GZIPOutputStream(baos);
ObjectOutputStream oos = new ObjectOutputStream(gzos);
now objects written to 'oos' will be gzipped and stored in the byte array of the 'baos'.
Cheers,
Brad
