I am making an online exam applet which will read questions from the database and will have a timer and all, something like the jcp exams. The problem is that browsers dont allow a JDBC ODBC connection because of the sandbox model. Please enlighten me as to how to overcome this problem. Any help will be much appreciated.

Solution 1. Set up security and sign the applet. Not recommended for general use because a lot of DBMS's use TCP/IP ports that get blocked by firewalls.
Solution 2. Use a 3-tier solution. Do all the JDBC stuff on the server and use a URLConnection to fetch/save data from the applet. Note that this has to be the same server that the applet was loaded from!
