Cannot connect to database via JApplet

Question

Hi,
I created a Java application which allows me to send information to my mysql database using the jdbc connector via a JFrame. However when i modified the file to be a JApplet the info will not sent and i cannot connect to the database? Any particular reason for this?
I need it to be a JApplet so i can add it to a browser window.
Code: ( java )
private void save ()
Connection conn = null;
try
Statement stmt;
String userName = "root";
String password = "PASSWORD";
String url = "jdbc:mysql://localhost:3306/DATABASE";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url, userName, password);
System.out.println ("Database connection established");
//Get a statement object
stmt = conn.createStatement();
stmt.executeUpdate( "INSERT INTO TABLE(Info i know to put in) VALUES('Values i know to put in')");
catch (Exception e)
System.err.println ("Cannot connect to database server");
finally
{if (conn != null)
          {try
               {conn.close ();       
System.out.println ("Database connection terminated");
catch (Exception e) { /* ignore close errors*/  }
As i said above it works fine as a JFrame but not as a JApplet. Any help would be great.
Thanks G

Your error reporting is not good. You print a meanningless message or ignore the error.
Print the stacktrace in the catch blocks.
Change the code, rerun it and then check the Java Console for output.
I'm guessing you'll see a security error. Unsigned applets can't access the client file system. If so, sign the applet.
