How do I add a java program to a weebly site?

I'm experimenting with Weebly, and I'm currently trying to add an arbitrary swing program to the Weebly editor. I have tried two approaches thus far, as shown here:
1: (Note: - replaces < and >)
-embed height=400 width=400 src="siteName/uploads/someNumbers/testapplet.class"--/embed-
2: (Same substitution as above)
-applet codebase="siteName/uploads/someNumbers" code="testapplet.ckass" width=400 height=400--/applet-
Upon publishing and viewing the page, the first one says I need a plugin to display the content, and the second one says my security preferences won't let me run java on the site, whereas I can run java pretty much everywhere else just fine.
What should I do to make this work? This could include some of the following:
Modifying my program (i.e. the java code itself)
Modifying how I upload the program (i.e. .class vs .jar)
Modifying how I display the program (i.e. the actual -applet- or -embed-)
For reference, here is the java code- just a basic JButton and JLabel, with the JLabel's value increasing upon each click of the button:
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class TestApplet extends JApplet
{
static int x = 0;
static JLabel l = new JLabel(x+"");
public void init()
{
setLayout(new FlowLayout());
JButton b = new JButton("Button");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
x++;
l.setText(x+"");
}
});
add(b);
add(l);
}
}

Sign in to weebly and click on the edit button next to your site name
On the "Elements" tab on the top, go to "Multimedia" and drag a file element onto your page.
Follow directions to upload your .class file. Name should be lowercase.
Hit the publish button and go to your published page.
Remember your .class file? Right-click on it and copy the link address or link location.
Go back to editing your weebly page.
On the "Elements" tab, go down to "More" and drag in the "Custom HTML" element.
Click to edit the custom HTML element- this is where we are going to put our applet code.
If my link location to my .class file was http://www.johndoe.com/uploads/3/3/2/6/3326331/countme.class, my applet code would read:
<applet codebase="http://www.johndoe.com/uploads/3/3/2/6/3326331" code="countme.class" width=something height=something></applet>
The idea is that the codebase tells the browser where to look for a .class file and the code itself tells it whick .class it is.
10. Publish again, and your applet should appear.
I haven't tried it personally, but I had a chat with a support support staff and they affirmed this method.
All the best!

Custom ToolBar with Java Swing for Desktop

I have created a GUI with Java Swing and wanting to create a custom toolbar according to my modules. Below are the images am wanting to use:
These images are placed in the same level as the src folder within my application. I am aware that I can perhaps create a jar with these images so that I can easily access them from within my application but do not know how. I have spent hours trying to make this work.
Below is my GUI that I have created ad wanting to beautify with these images for the toolbar else create an array of labels that will act as a navigation but either approach I couldn't get it to work.
The code below was my last attempt on this:
JToolBar toolbar1 = new JToolBar();
ImageIcon client = new ImageIcon("clients.png");
ImageIcon timesheet = new ImageIcon("timesheets.png");
JButton clientTB = new JButton(client);
JButton timesheetTB = new JButton(timesheet);
toolbar1.add(clientTB );
toolbar1.add(timesheetTB);
add(toolbar1, BorderLayout.NORTH);
I even moved these images and placed them within the class that's calling them.
What could I be doing wrong, please help?

You have a look at the JavaDocs for ImageIcon(String), the String value is "a String specifying a filename or path"
This is a problem, because your images aren't actually files, any more, they have been embedded within your application (typically within the resulting jar file) and no longer be treated like "normal files".
Instead, you need to use Class#getResource which searches the application's classpath for the named resource, something like...
// This assumes that the images are in the default package
// (or the root of the src directory)
ImageIcon client = new ImageIcon(getClass().getResource("/clients.png"));
Now, I have a personal dislike for ImageIcon, because it won't tell you when the image is loaded for some reason, like it can't be found or it's the wrong format.
Instead, I'd use ImageIO to read the image
ImageIcon client = new ImageIcon(ImageIO.read(getClass().getResource("/clients.png")));
which will do two things, first, it will throw a IOException if the image can't be loaded for some reason and two, it won't return until the image is fully loaded, which is helpful.

JFrame's icon not displaying

I've got a Java application with Swing's JFrame as a main GUI unit. I've set the icon to it via setIconImage(). When I run this program in NetBeans, everything works fine and the frame's icon displays. But when I compile it and try to run jar-file (with JRE7), the application has standard icon with Duke. How do I change that icon when running app outside NetBeans?
UPD:
OK, here's the code:
public static void main(String[] args) throws IOException{
URL imgUrl = Polygon.class.getResource("/imgs/icon.png");
Image img = ImageIO.read(imgUrl);
JFrame f = new JFrame();
f.setSize(new Dimension(500, 500));
f.setIconImage(img);
f.setVisible(true);
}
UPD2:
I've added this line to the end of the code:
JOptionPane.showMessageDialog(null, new ImageIcon(img));
Everything's fine with the image! It loads! BUT it's not displayed as the icon.

When you run the application from inside Netbeans, the files from your project folder are available, but if you run the compiled JAR yourself they may not.
Read this example (note the comments) to load your image properly.

Try getClass().getResource("imgs/icon.png"). It works for me. Note the difference between absolute and relative path. You may not need the leading /.

export a JOGL applet and embedd into a html page

It is some time that I'm testing opengl with java and JOGL. I have a good result and I wan to publish it on the web, but I have a problem. I'm in eclipse, and I'm testing an Applet with JOGL.
EDIT: Thanks to Ricket answer it fixed this problem
first of all i have this run time error (but the program works correctly):
java.lang.IllegalArgumentException:
adding a window to a container at
EDIT: but it still doesn't work:
then I found this incredibly clear page
and I did what is said. I open html with the browser, the libs are downloaded, but it stops at Starting applet AppletHelloWorld, as that is the name I gave to my applet.
Maybe I am missing something like a main function or exporting the jar properly?
This is my main code:
public class AppletHelloWorld extends Applet
{
public static void main(String[] args)
{
JFrame fr=new JFrame();
fr.setBounds(0,0,1015,600);
fr.add(new AppletHelloWorld());
fr.setVisible(true);
}
public void init()
{
setLayout(null);
MyJOGLProject canvas = new MyJOGLProject(); //MyJOGLProject extends JFrame
canvas.run(); // this do setVisible(true)
} //....

Just as the error says, you're trying to add a window to a container. A JFrame is a window. You can't add a JFrame to anything, including a Container. I think perhaps you either don't know what a JFrame is, or don't know what a Container is.
Ideally you would have MyJOGLProject extend GLEventListener instead. Then your init function would make a new GLCanvas, add an instance of MyJOGLProject to it (via addGLEventListener), and then add the GLCanvas to your applet.
Alternatively, if you're okay with the applet popping up a JFrame, then simplify your init method:
public void init() {
setLayout(null);
MyJOGLProject canvas = new MyJOGLProject();
canvas.setVisible(true);
}
That should do it.

Use JApplet. I think that's the reason why it fails.
(Use Webstart with JNLP in NetBeans)

Having difficulty add a custom icon to a JFrame

I have been trying to change the icon in the frame. I have virtually tried everything:
The icon is 16x16 which is the right size ....doesn't work
I've trying PNG,GIF and JPG formats none of them work.
Tried different way of setting the icon....doesn't work.
I've tried relative (local paths) e.g. "icon.gif" and absolute paths e.g. "c:\work\java\icon.gif" ...doesn't work
Here is my code and see if you can figure it out
Thanks
Oli
import javax.swing.*;
public class androidDriver
{
public static void main(String[] args) throws IOException
{
JFrame f = new JFrame("Android Data Viewer");
f.setResizable(false);
f.setSize(300,300);
f.setLocationRelativeTo(null);
f.setVisible(true);
f.setIconImage(new ImageIcon("androidIcon2.gif").getImage());
}
}

If you put the image in the same directory as the class file then the following should work for you:
f.setIconImage(new ImageIcon(androidDriver.class.getResource("androidIcon2.gif")).getImage());
Also would suggest setting the icon image before you make the frame visible
f.setIconImage(new ImageIcon(androidDriver.class.getResource("androidIcon2.gif")).getImage());
f.setVisible(true);

I suspect you may have to actually wait for the image to load using a MediaTracker. It's likely that the image is still loading at the point the frame setIconImage references it, so it does nothing.

Have you tried using Toolkit.getDefaultToolkit().getImage("androidIcon2.gif")
And two other things:
Does the image exist? The code you posted will fail silently.
Is it formatted properly? (though I assume Java could handle it if it wasn't)

Make a separate folder next to the source folder then put your image in there, and then use ImageIO to get the image like so:
f.setIconImage(ImageIO.read(new File("res/androidIcon2.gif")));
Also, if that doesn't work, try saving the image as a .png instead of a .gif.
