Internet + Database

I am building the following system as part of a college course.
We need a Java powered G.U.I
The user will have to be presented with a map of a city, either by web browser or applet.
This map should be an image map, so the user can click two points on the image.
These two points need to be sent to an SQL query to query a Microsoft Access Database (97).

Any suggestions how I can store the names of the points the user has clicked on without violating the file IO restrcitions of applets or WWW Browsers
