Answer 1

You can certainly send messages through RabbitMQ from Java. There is a Java client-side library for interfacing with RabbitMQ - http://www.rabbitmq.com/api-guide.html

This page describes the Celery message format - http://docs.celeryproject.org/en/latest/internals/protocol.html. One flavour uses JSON, and there are lots of existing Java libraries for reading and writing in JSON; see http://json.org

It's better to have example code and could be run directly

You are correct.

The page linked above includes code snippets, and the RabbitMQ Java library has some (small) examples. (At least, that's what the page says.)

Answer 2

Simplest form would be to write a simple python script which simply adds a task to celery, and call this python script from java (Runtime.exec() or similar method).
