Java Applet + HTML
Question
I have a problem with embedding my applet in html file. I've got "no class def found error" in browser. This is the simple applet connected with MySQL database. This is the code:
public class Nowy extends JApplet {
JPanel panel;
JButton count, end;
JLabel result;
int score;
String name = "Matthew";
@Override
public void init() {
panel = new JPanel();
panel.setLayout(null);
add(panel);
result = new JLabel("0");
result.setBounds(10,10,100,30);
panel.add(result);
count = new JButton("COUNT");
count.setBounds(10,60,100,30);
panel.add(count);
end = new JButton("END");
end.setBounds(130,60,100,30);
panel.add(end);
count.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
score = score + 5;
result.setText(""+score);
}
});
end.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
con();
}
});
}
public void con() {
try{
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/res", "root", "");
Statement stmt = (Statement) con.createStatement();
String insert = "INSERT INTO wyniki VALUES ('" + score + "', '" + name + "')";
stmt.executeUpdate(insert);
}catch (Exception e) {
System.out.println(e);
}
}
And this is my html code:
<applet code = 'Nowy.class'
archive = 'Nowy.jar mysql-connector-java-5.1.27-bin.jar'
width = 300
height = 300>
<param name="permissions" value="sandbox" />
</applet>
I have no idea if it's wrong path in html or other?

Try this.
<script src="//www.java.com/js/deployJava.js"></script>
And this to <body> section:
<script>
var attributes = {codebase: 'http://my.url/my/path/to/codebase',
code: 'my.main.Applet.class',
archive: 'my-archive.jar',
width: '800',
height: '600'};
var parameters = {java_arguments: '-Xmx256m'}; // customize per your needs
var version = '1.5'; // JDK version
deployJava.runApplet(attributes, parameters, version);
</script>

If you want to run your Applet into Browser than you must have to signed your JAR file first. Here is the reference for more details:
