Java EE (Java Enterprise Edition) General Discussion

hello all,
i search this forum ,but did not get any satisfactory reply, i need to create a banner that keeps rotating with diff. values from a database, this banner should be present throughout the user navigation,(the one like shown in bottom part of screen in news channels)
what is the best way to do this ? any code would be helpful, i heard that it can be done in javascript but i do not know how to connect to database thro. javascript.
if u have any suggestions do say,
best wishes,
Vishal
