Applet not working in browser

I designed an applet that connects to mysql database and saves data from applet form to database.The applet is working fine in netbeans ide but it is not working in browser,it is unable to update database from the browser.

Please help me solve this problem.

How did you embed your applet in html page? And how did you make connections with database?

I embeded applet as follows
<APPLET codebase="classes" code="selection2/Selection2.class" width=350 height=200></APPLET>

con = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/facsel","root","root");

at lease add
ARCHIVE="your jdbc jar"

and other jar that you used in the applet
