I'm going to use stringing bits of text together. But text generating  
is not
an issue here. The issue is how to make this stringing driven by
description of ocaml records.

I have few hundreds of types. For each ocaml type I want to generate
corresponding Java class with function (constructor) that initialize an
object of this class from json string. E.g.:

type json create_order_response = {
   order_id : int;
   order_code : string;
   order_price : int;
   ...
}

... must be translated in something like:

public class CreateOrderResponse extends ... implements ... {
	private int id = 0;
	private String code = "";
	private int price = 0;
	...
	public CreateOrderResponse(String json) { ... }
};

P.S.: I'm using json-static library and its preprocessor module
(http://martin.jambon.free.fr/json-static.html) to automatically  
generate
functions, used to convert records (marked by "json" keyword) to strings
in json format and vice versa.
