    Applet with mysql

    Hi guys!
    I dont know if this is the right place where i have to post it! If it is not please let me know where I should post it....

    I have a small problem using the applet with the driver mysql.
    This is what i managed to do:
    I have created a java program which is connected with a database mysql using the driver jdbc.
    It works fine when i run the program from the netbeans tool.
    Now I would like to create an applet and i have created this class:

    import Webpages.InitialWebPage;
    import java.awt.*;
    import java.applet.*;

    public class RunApplet extends Applet
    {
    InitialWebPage f;
    public void init()
    {

    f = new InitialWebPage();
    }


    }



    The class InitialWebPage is the one which contains the main method.

    Then I have done:

    <html>
    <head>
    <title></title>
    </head>
    <body>
    This is an applet:<BR>

    <applet code="RunApplet.class"

    ></APPLET>
    </body>
    </html>


    I have put this file in the same folder of the file RunApplet.class

    But I have received this exception:
    java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
    java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM.0)


    I tried to resolve the first exception and I created a jar file: anto.jar which contains the RunApplet.class and mysql-connector-java-5.1.0-bin.jar

    I modified the html code in this way :

    <html>
    <head>
    <title></title>
    </head>
    <body>
    Il seguente è un applet:<BR>

    <applet archive="anto.jar" code="RunApplet.class">

    </body>
    </html>



    But now I received this execption:
    java.security.AccessControlException: access denied (java.util.PropertyPermission java.home read)

    Please could someone help me to fix this problem? What I have to do to connect an applet with a mysql database?

    thanks in advance

    antonio

    Re: Applet with mysql

    I guess the post is a little bit out of topic, but take a look at this example: http://tecfa.unige.ch/guides/java/st...ingApplet.html

    Or more specifically, at this source code: http://tecfa.unige.ch/guides/java/st...ingApplet.java
