Why am I getting a 404 requested resource not available error from Tomcat 7
I have recreated this project in Eclipse as many ways as I can think of and continue to get this same error-
HTTP Status 404 - /SpringTest/hello
type Status report
message /SpringTest/hello
description The requested resource (/SpringTest/hello) is not available.
Please help me find the issue in my code below.

I think that the problem is that your web.xml only maps *.html requests to your servlet, and you are sending it a request without a .html suffix.
One solution is to change the servlet mapping. For example
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.</url-pattern>
</servlet-mapping>
matches any suffix, or
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
matches any path.
As @Stephen suggested change the url pattern
OR
Call the controller from you index.jsp as hello.html
