Javascript receiving data from a Lightstreamer server


This project is to add a data feed from a Lightstreamer (LS) server to an existing html web page, as following - all in javascript:

The structure; an existing web page in HTML, placed on a normal webserver port 80:

This web page is using a javascript file "[url removed, login to view]".

I need to add a data feed from the LS server to the existing web page, the LS server is on another IP address and on port 8080.

1) A function which starts the LS according to below.

2) A function which defines a 2D array in [url removed, login to view] , 100 rows with 5 columns, each row has an unique ID value in first column, such as 1134.

3) A function in [url removed, login to view] which subscribes to an item at LS having 4 parameters, item name is the ID of the row above.

4) A function in [url removed, login to view] which is called when new data has been received by the LS connection, I suppose; OnReceive(row) or OnReceive(ID);

5) A function in [url removed, login to view] which is called on the events of LS, OnConnect, OnDosconnect, OnError.

The LS server is already up and running, I can provide the IP adr and port of the LS server - thus only the html page with javascripts are needed to develop.

I further have a simple application developed in C++ Builder 2010, which connects via TCP to the LS server handling the backend, and which responds to subscriptions and sends the data subscribed.

Coders who have good experience with LS are preferred, please indicate your experience with LS while bidding - and please indicate your experience with C++ Builder if any.
