Solving JPython Applet Problems

If you are having problems getting a JPython applet to run on your browser, you should follow the following steps.

1. Make sure that you have a jdk 1.1 compliant browser.  At the moment these include:

  1. SUN's HotJava
  2. Microsoft's Internet Explorer 4.0
  3. Netscape's Navigator 4.06 or later
  4. SUN's Java Activator - not currently enabled

2. Make sure you don't have any old releases of JPython in your class path.

  1. If you are running a SUN (or SUN-like) VM you need to make sure your CLASSPATH environment variable is not pointing to any directories with JPython .class files
  2. If you are running a MS VM, you should probably check out the registry entry under LOCAL_MACHINE/Software/Microsoft/Java VM/Classpath

3. Send mail to jpython@python.org explaining your problem.  Include the following information:

  1. What OS (name and version) and Browser (name and version) you are running
  2. A copy of your Java console window after failing to run an applet
  3. The URL of the applet that didn't work for you
