Hello Dave Developer
in your jsp adjust your class to the package.className as with
<jsp:useBean id='clock' scope='page' class='cal.JspCalendar'
type="cal.JspCalendar" />

to servlets not listed here with a request like this:
http://localhost:8080/{context-path}/servlet/{classname}<http://localhost:8080/%7Bcontext-path%7D/servlet/%7Bclassname%7D>
but this usage is not guaranteed to be portable. It also
makes relative references to images and other resources
required by your servlet more complicated, so defining
all of your servlets (and defining a mapping to them with
a servlet-mapping element) is recommended.
Servlet initialization parameters can be retrieved in a
servlet or JSP page by calling:
String value =
getServletConfig().getInitParameter("name");
where "name" matches the <param-name> element of
one of these initialization parameters.
You can define any number of servlets, including zero.

<description>
This servlet plays the "controller" role in the MVC architecture
used in this application. It is generally mapped to the ".do"
filename extension with a servlet-mapping element, and all form
submits in the app will be submitted to a request URI like
"saveCustomer.do", which will therefore be mapped to this servlet.
The initialization parameter namess for this servlet are the
"servlet path" that will be received by this servlet (after the
filename extension is removed). The corresponding value is the
name of the action class that will be used to process this request.

Re: error number 500
Posted by David Smith <dn...@cornell.edu>.
Take a look at the messages in the log files. You should see details
in there regarding what happened. They are located in the /logs
directory where tomcat was installed.
