ideas for a "buddy list"

[jonneymendoza]

hi i am trying to design and create a buddy list for my instant messenger. i have created a Jtree with online and offline has the child nodes.

i then going to create a vector list stored in a txt file with users names, and i will load that list in a jtree..

the problem im having is how can i load data from the vector list into the jtree? And most importantly how can the Jtree autmaticly updates itself when a user is offline/online?

BTW i have a MYSQL server that knows when a user is offline/online via JDBC...

any suggetsions?
