<jsp:useBean id="myNameHandler" scope="request"
class="myForm.NameHandler"/> is what you really want if you are just
forwarding/including requests.

<form method="get" action="showName.jsp"> is safer.

You must specify a <jsp:useBean> before you use <jsp:getProperty> or
<jsp:setProperty>, (or suffer the compile error you are currently
getting).
So try:
<html>
<body>
<jsp:useBean id="myNameHandler" scope="request"
class="myForm.NameHandler"/>
Hello, <jsp:getProperty name="myNameHandler" property="username"
/>!
</body>
</html>
