Hi friends,
I have a short web application to finish. The application is:
Create JTree on the GUI and similar component on the web. The GUI screen 
created using JTree is front-end, and a similar component on the web is 
back-end. The list on the tree should read from an array, and the 
information in the array is read from the database.
I think I may use servlet and JDBC to connect to database. But How to 
connect the GUI screen at front-end with the component of back-end?
I'm not sure Servlet can call JTree GUI screen or not?
Please give a help, welcome to any ideas. Thank for your help.

James
