Java SE (Java Platform, Standard Edition)

Hi guys,

I have a Java Applet that was written years ago in jdk 1.4 and is no longer working for clients who've downloaded JRE 1.6. It worked previously for JRE 1.5.

The Server: JDK 1.4
The Clients: JRE 1.6

My scenario is an old application being hosted on tomcat 4129 under JDK 1.4. The applet was signed in 1.4, etc. Anyhow, since the clients have updated to 1.6 they've been getting all kinds of NullPointerException errors that don't show up in JDK 1.5. I would LIKE to re-build this but for the moment I'm looking for a band-aid to keep it running for a little while longer.

My Applet sits in a web application that uses FRAMES, so the Applet is in a FRAME.

my applet:

          Your browser is completely ignoring the <APPLET> tag!

And it is being loaded by a javascript call:

function waitForApplet() {
    setTimeout("isAppletLoaded()", intSleepTime);
    document.applets[0].showMapWhenReady();
  }
