You are right.  I truly haven't the slightest idea how this got there, but in my
WEB-INF/classes directory was a tomcat org directory tree of an old version of
tomcat.  It's a mystery!

I deleted it and now things work fine.  Thanks for the extra push.

RE: W2k/cygwin/4.0.2-b2/Incompatible type for method.

[Zemen, Franz]

Hi Christopher,

I believe this isn't anything to do with Win2K but rather with a version of
the JSP package that gets loaded into your classpath.

In the older servlet/JSP package, PageContext.handlePageException accepted
only a java.lang.Exception (see Javadocs for J2EE 1.2.1).  The newer version
of PageContext (certainly JSP 1.2) contains a handlePageException that
accepts a Throwable.  I'm assuming that in your email below "t" is a
Throwable, and then
of course it would need to be cast specifically to an Exception if the
loaded PageContext class was not from the latest release.

Is it possible that somewhere on your classpath an older version of J2EE or
JSP libraries are loaded first?  That would be one possible cause of what
you are seeing.

Hope this helps,

Franz Zemen
