You could serialize the data structure to JSON, and then deserialize it from Perl using JSON.	[reply]

Or XML as well, using XML::Simple from cpan.	[reply]

If you use JSON or XML, be mindful of your character sets. Java IS UTF-16, which covers ASCII. If you're doing it outside of ASCII, be mindful. XML has character encoding, to its advantage but takes more work to rig up.	[reply]

It should be no real problem to have Java create UTF-8 encoded files/streams (both JSON and XML), and JSON can read UTF-8 data just fine... (Similarly for XML)	[reply]

Agreed. As long as no UTF-16 chars are used, which is really easy to do in java since strings are all UTF-16, it's all gravy. Java strings are UTF-16 A good XML writer that prevents you from going outside of the declared format will protect you from future mistakes. Down side is the extra effort in using some XML api over others. JSON is usually gravy in all languages. Gravy.. mmmm...	[reply]

Hello, Depending on your requirements, I'd probably just use Inline::Java and let it take care of the serialization. regards,	[reply]
