JDBC in applet

I created an applet using JDeveloper which imports the BApplet class and then deployed to a .jar file. But I always get a java.lang.noClassDefFound error when I try to run the applet in IE. But the jar includes BApplet.
Here's my mod of the bounce program example:
import java.applet.*;
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import java.text.*;
import java.util.*;
import java.util.zip.*;
import BApplet;
import BFont;
import java.sql.*;
public class bounce extends BApplet {
// Bounce
// by REAS <http://www.groupc.net>
// When the shape hits the edge of the window, it reverses its direction
// Updated 1 September 2002
int size = 60; // Width of the shape
float xpos, ypos; // Starting position of shape
float xspeed = 1.8f; // Speed of the shape
float yspeed = 1.2f; // Speed of the shape
int xdirection = 1; // Left or Right
int ydirection = 1; // Top to Bottom
private Connection conn;
private String Query;
private String SQLerr;
Statement stmt;
ResultSet rset;
private String[] mnames;
int x = 1;
int i = 0;
BFont f = loadFont("CenturySchbk.vlw.gz");
void setup()
{
try {
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection
("jdbc racle:thin:@10.9.9.99:1521:research", "userid", "passwd");
} catch
(Exception e) { e.printStackTrace();
}
Query = "select fname from bctcnames" ;
try {
stmt = conn.createStatement();
rset = stmt.executeQuery (Query);
// mycount = rset.getFetchSize();
if ((rset = stmt.getResultSet()) != null) {
while (rset.next()) {
mnames[x] = rset.getString(1);
x = x + 1;
}
}
} // end try
catch (SQLException e) {
SQLerr = "SQL Error:" + e.getMessage();
}
setFont(f, 50);
size(200, 200);
background(102);
noStroke();
// Set the starting position of the shape
xpos = width/2;
ypos = height/2;
}
void loop()
{
// Update the position of the shape
xpos = xpos + ( xspeed * xdirection );
ypos = ypos + ( yspeed * ydirection );
// Test to see if the shape exceeds the boundaries of the screen
// If it does, reverse its direction by multiplying by -1
if (xpos > width-size || xpos < 0) {
xdirection *= -1;
}
if (ypos > height-size || ypos < 0) {
ydirection *= -1;
}
// Draw the shape
if (i == x) {
i = 1;
} else {
i = i + 1;
}
ellipse(xpos, ypos, size, size);
text(mnames[i], xpos, ypos);
}
}
