How to build a JSON object in forms

Dear Gurus,

We have a requirement where we communicate between Oracle forms and Java. As part of this integration, we pass certain info from Forms to a custom build Rules engine in JAVA and get the instruction back from the engine in form based on which further process happens in the forms application.

Our current integration approach is via a set of tables where the forms inserts the necessary data into the tables and the engine reads the data from these tables and processes the information and inserts the instruction in the integration tables, The forms application then reads the instruction for further processing.
