XSLT applet.

[Benjamin Jones]

I have been fighting a problem with writing an XSLT applet for several
days now.

The following code works in a command line application, and in the
applet viewer for provided with IBM eclipse. It fails in any browser,
and in the Java SDK's applet viewer.

The line marked below has an uncaught exception that shows the following
text:

Usually code that works in an application and fails in an applet is the
result of a classpath problem. I am using xalan and xerces in this
case, both of which are in the classpath.

Any suggestions regarding the origins of this problem are welcome.

Thank you,

Ben Jones
