Do you have the Java2 plugin? If it recognizes all of your other applets then you may want to get the latest version of the plugin and install it and see if that does the trick. You can get it at http://java.sun.com/products/plugin/index.html. Other than that my next questions would be: Are you getting an error message in the browser? Does the applet load at all? What does your HTML code look like? do any of your applets work? Even without swing?
