Thanks for your responses... I kind of get the thing working. Here is my logic:
On the server-side, I periodically query the database for new records and append them to my Object[][] data. Whenever the client click "Refresh" button for example, the server-side will send the data[][] back in JSON format. There is a problem with this approach, however, as the Object[][] data array will grow very large over time and consequently, the JSON data as well. That brings up another set of questions :-) 1. On the server-side I would like to store only new records in data[] [], and let the client keep track of past records. Server will only send new data since the last client refresh. How do I append new data into BufferedStore and/or JSONReader and refresh the livegrid? 2. Instead of waiting for the user to click "Refresh" button, I would like to auto refresh the grid periodically -- How can I achieve that? What functions does the "Refresh" button invoke? Appreciate your inputs.
