Java SE (Java Platform, Standard Edition)

Hi All -

I have a rather puzzling problem with an applet I have running from a JAR. On Windows 2000, when I have JRE 1.4.1_XX installed, the applet loads and runs without any problem. Then I install JRE 1.4.2_XX, so that now I have both. I have problems whenever 1.4.2 is installed, regardless of which runtime I choose from the control panel, although the exception is different. Also, JRE 1.4.2 alone also does not work. The last weird thing is that everything works FINE on Windows XP regardless of which JREs are installed! Details are below, and any help is very much appreciated!!!

Thanks,
Ed

The exceptions below were generated when 1.4.2 and 1.4.1 were both installed. The exceptions that occur with using 1.4.2 as the runtime when 1.4.1 is also installed are the same as when 1.4.2 is installed alone.

When the 1.4.2_XX is used as the Runtime, I receive the exception:

If I use 1.4.1_XX as the runtime, it STILL does not work (that's right, the mere presense of 1.4.2 somehow causes a problem.) but the exception is different. When the applet is loading, this exception appears:

---------------------------------------------------------------------------------------------------------java.lang.NoSuchMethodError: sun.applet.AppletPanel.changeFrameAppContext(Ljava/awt/Frame;Lsun/awt/AppContext;)V

Then when I click the first action in the applet, instead of the ExceptionInInitializerError exception, I get:
