Troubleshooting
If you see "Applet can't start: class ______ not found" in your browser's status line, it can mean one of two things:
- The .class file(s) are not named correctly. Java is case-sensitive, so be sure to follow precise capitalization.
- The .class file(s) are not in the correct directory. They should be located in the path indicated in the CODEBASE= portion of the <APPLET> tag, or the directory of your HTML document if no CODEBASE= is specified.
To further enable you to locate the problem, you may start the Java console (under MSIE or NS). If you're using Netscape, you'll find it under the Communicator item in the Netscape menu (Java Console). Using MSIE, you'll find it under View (Java Console) in the MSIE menu. The Java Console will give you more details than the status bar, and may help you find out why the applet will not run. Often, it will show you that the applet depends on more than one class file, and you'll need to upload that class file to your server as well.
The applet may be written for a newer JDK than you have on your system. Most applets will work with MSIE4, and Netscape4 as well, provided you have applied the latest JDK 1.1 patch from http://developer.netscape.com.
