serializing and deserializing an object between Unix and Windows

Experts,

I would like to produce data files that can be shared by servers implemented in Java that are running on Unix and Windows without having to fuss with endianness if possible. Is there a method/object Java provides where an object can be serialized/deserialized on a big endian platform and deserialized/serialized on a little endian platform seamlessly?

Thanks.

Java uses the same byte order on any platform. readObject/writeObject won't be affected by host byte order

Serialization/Deserialization can happen in any platform as long as the same version of the jdk/jre are used...  For instance v.1.1 and 1.2 will not work.  As far as I know 1.3 and 1.4 should be fine!

You need to make sure that the JDKs/JREs being used are using the same class version! Class version differences and/or incompatibilities will cause errors and failures. See here for more information (including all previous versions of Java): http://java.sun.com/j2se/1.4/compatibility.html

That's actually only the case for backward compatibility. Something serialized in 1.4 will deserialize OK in 1.5

Not true. Read the comments in the Swing classes for instance. No guarantees are made regarding backward or forward compatibility of any class, ever.

Good to know. And lucky too! :-)

1.3 -> 1.4 is OK
1.3 -> 1.5 is OK
