Sorry my mistake, Its ok now..
I was trying to serialize an object to a String. This String can then be used anywhere (e.g. in a cookie).


Here is what I did:


First, Use "ByteArrayOutputStream" with "ObjectOutputStream" to get a ByteArray representing the object to be serialized -or a String using "ByteArrayOutputStream.toString()" function. The resultant String can be used to de-serialize the object by converting the String to a byte array -using String.toBytes()- and then using "ByteArrayInputStream" with "ObjectOutputStream" to retrieve the object.


This would only work if the object does not contain arrays of non-primitive types. The solution was to specify the character encoding of "ISO8859_1" when converting between ByteArrays and Strings.


i.e. ByteArrayOutputStream.toString("ISO8859_1") and
String.toBytes("ISO8859_1").


I don't know why "ISO8859_1" though, maybe because I'm using Windows.


Hope this is useful to someone.
