    Default applet does not connects to database in browser

    Hello programmers,

    could someone point me where to start for this problem:

    created applet using NetBeans. Part of the applet is to connect to database. When I run it on NetBeans - works fine, but when open .html file (auto created by NetBeans in build folder) connection does not happen. Everything works but does not connect. I am working at the moment on localhost.

    Code in html:
    <APPLET codebase="classes" code="nwt/name_applet.class" width=650 height=700></APPLET>

    Where do start to look for problem? Please help.

    Thank you.

    View the console output. I know firefox has an option to view the java console and view println's or any exceptions being thrown (My guess is that a SecurityException is being thrown, in which case you need to sign your applet)

    thanks doWhile.

    I did what you said, console gave me an error
    java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

    How do I fix this? Why loading from NetBeans everyhing works fine?
    please advise.

    You need to add the driver to your classpath. There are probably hundreds of posts here that describe how to do this so rather than reproduce all that info I recommend you do a search of the forums. For example, here is a recent post that discusses this: Problem loading JDBC SQL driver.
    This situation may be a bit different because it is an applet, you need to add the jar to the appropriate server location and add it to the archive tag of the applet
