Making a jtable auto updates itself from a mysql table

Question

Pretty much what the title says. How can i auto update the jtable for every time my mysql table is updated in anyway? i am implementing this auto update function in my admin program which displays a list of users who are online etc. from the moment a user is offline/online or changes other details displayed in my jtable, i want it to auto update the jtable as soon as the actual mysql table has been updated with new data...
I was thinking of re doing the whole jtable i made and create a thread for that table that has a infinite while loop that keeps repainting the jtable with the new updated data from a mysql table query eg select * from table and store the data into a resultset which then gets transferred into a vector. Load the vector into the jtbale and their ya go�.
what you think of this approach? Is their a better way to do this?
at the moment, as soon as my application opens, the jtable views all the data from my sql table, however if it doesnt auto updates itself, cheers

i am implementing this auto update
function in my admin program which displays a list of
users who are online etc. from the moment a user is
offline/online or changes other details displayed in
my jtable, i want it to auto update the jtable as
soon as the actual mysql table has been updated with
new data...Well you can make some changes to make implementation easy
Ex: Create a table to keep a log of the changes in the system the dmin program read the log and replicate the changes as specified in the log on the table model.
When reading the log the admin program keep track of the sequence no of the last read log entry and it reads ony the entries which has larger seq numbers than the last read seq no
I dont think that it is critical to make this to be cloase to real time. An Update once a 1 or 2 secs should be sufficient.
