In Perl, it's trivial. The JSON module from CPAN will round-trip any
arbitrary structure of any depth into a JSON string in a very efficient
manner. See http://search.cpan.org/~makamaka/JSON-2.50/lib/JSON.pm
use JSON;
$encoder = JSON->new();
$json_string = JSON->encode( $complex_structure );
$new_struct = JSON->decode( $json_string );
For Java, it appears that JSONStringer provides similar functionality
although it's limited to 20 levels. I haven't personally used it,
however. See: http://www.json.org/javadoc/org/json/JSONStringer.html
You can embed Perl inside a Java program using PLJava -

You can embed Java inside a Perl program using Inline::Java -

So, how would you encode json, assuming no limits on nesting depth?
Right now I'm thinking of "flattening" the structure, where you get the
full name as list<string>, and the value as a string, which is either a
simple value or empty, and you look for children to get the value of the
aggregate.
Any thoughts?
