Answer 1

You can use different libraries to convert from diferent java objects to JSON

For example the library json-simple http://code.google.com/p/json-simple/

In the json-simple page you can see some examples of encoding,decoding, and JSP & AJAX with these library.

Answer 2

Structure a Java object in a similar fashion and then use a serialization mechanism such as json-simple or xstream with Json Driver

for instance new XStream(new JettisonMappedXmlDriver()); xstream.toXML(object);

Answer 3

Got it.

Create JSONObject. Create JSONArray.

Merge.
