Cross-platform and language (de)serialization

Question

I\'m looking for a way to serialize a bunch of C++ structs in the most convenient way so that the serialization is portable across C++ and Java (at a minimum) and across 32bit/6

Answer 1

You need ASN.1! (Some people refer to this as binary XML.) ASN.1 is very compact and thus ideal to transfer data between two systems. And for those who don't think this is ever used: several Internet protocols are based upon the ASN.1 model for data serialization!

Unfortunately, there aren't many libraries available for Java or C++ that will support ASN.1. I had to work with it several years ago and just couldn't find a good, free or inexpensive tool to allow support for ASN.1 in C++. At Objective Systems they are selling ASN.1/XML solutions but it's extremely expensive. (The ASN.1 compiler for C++ and Java, that is!) It costs you an arm and a leg at least! (But then you will have a tool that you can use with only one hand...)
