ORACLE APEX POST Restful Web services

Question

Any examples and/or ideas into how to insert a XML or JSON style document into column with XMLtype, varchar2, clob or blob type using an Apex post restful web service? I don't want to use SQL loader, external tables or something that requires a directory in the database server. 
Oracle Apex 4.2
Apache tomcat 7 web server
Oracle Apex Listener 2.0
Oracle database 11.2.0.3
thank you!

MK,
I am able to insert into a table the following json document;
{"name": "John", "age": "21"}
Here is the code behind it.
<code>
create table students (
name varchar2(100),
age varchar2(100));
begin
insert into students(name, age)
values(:name, :age);
end;
</code>
This works, But the following will fail,
{"name": "John", "age": "21"}, {"name": "Mary", "age": "22"}.
I would like to load the document into memory and insert into a table.
