Hi Bob Moranski,
You are doing basic mistake in invoking servlets.
First of all why you have kept "ThisHtml.html" in "classes" directory ?. The "classes" dir should not contain HTML files it should contain your servlet files or pakage.
Have you defined "server.xml" which is in TOMCAT configuration dir ?. I thing you are using pakages in your servlets, hence your URL will be
either
http://127.0.0.1:8080/ch2/servlet/MyServlet or
http://127.0.0.1:8080/servlet/ch2.MyServlet Keep your HTML or
JSP files in "\ch2\ " directory
If you keep your MyServlet.class in "\classes\ch2\" directory then The first line in your MYServlet.java will be "package ch2;"
Include the following in your "server.xml" file
<Context path="/ch2"
docBase="webapps/ch2"
defaultSessionTimeOut="30"
isWARExpanded="true"
isWARValidated="false"
isInvokerEnabled="true"
isWorkDirPersistent="false" />
