Thanks for the reply.
To confirm one thing about "only types that can be converted to JSON".
Suppose I have a class like:
public class User {
public String name;
public Address address ;
}
public class Address { public String line ; }
The User can be converted to JSON, so I think the following should work
well, right?
User u = new User() ;
// ....assign some values to the instance
document.putProperties( "somekey", u ) ;
Thanks again.
