pro_jsp thread: Trouble with jsp finding .class file in Tomcat 3.2

I am working with the 'spellcheck' example in Chapter 2 (p 46 in my
book), and cannot get the JSP file to 'find' the SpellCheck class file.
I am using Tomcat 3.2.2 via IIS on an NT workstation. I am able to run
the earlier JSP-only examples from the book without errors, and to run
the JSP-to-Bean examples provided with the Tomcat installation. My java
file compiles without errors, and if I stick a main method in it I can
run it from the command line. The class is not part of a package. In
wordpro.jsp, I'm including these lines to get at the class:
<jsp:useBean id="spellcheck" scope="request" class="SpellCheck" />
<jsp:setProperty name="spellcheck" property="*" />
then later in the JSP I get at methods etc with syntax like this:
'out.println(spellcheck.check());'
When I run the example, the error I get is this:

My classpath (displayed when I startup Tomcat) is:
'Using CLASSPATH:
d:\jakarta-tomcat-3.2.2\classes;
d:\jakarta-tomcat-3.2.2\lib\ant.jar;
d:\jakarta-tomcat-3.2.2\lib\jasper.jar;
d:\jakarta-tomcat-3.2.2\lib\jaxp.jar;
d:\jakarta-tomcat-3.2.2\lib\parser.jar;

d:\orant816\jdbc\lib\nls_charset12.zip;
d:\jakarta-tomcat-3.2.2\webapps\;.;;
c:\jdk1.3.0_02\lib\tools.jar'
It also says 'Including all jars in d:\jakarta-tomcat-3.2.2\lib in your
CLASSPATH.'
My JSP & HTML file for this example is in
d:\jakarta-tomcat-3.2.2\webapps\wench_test\jsp\46\
I have left my compiled SpellCheck.class there, and also put a copy of
it in
d:\jakarta-tomcat-3.2.2\webapps\ROOT\WEB-INF\classes\ (because I read
that any class files in there would be automatically found by Tomcat --
s'not true).
I had also read that the class file HAD to be JAR'd and put in various
places (including d:\jakarta-tomcat-3.2.2\lib\), which also didn't
work.
Any help would be appreciated. I've been messing with this for a few
days and reading anything I can find on the issue, and the basics (make
sure the class and/or jar file is in the classpath, etc) isn't helping
me.
