Actually, the mapping rules are defined in the Servlet API spec. There are
for types of valid mappings:
* Exact path mapping, e.g. the URI /foo is mapped to a specific servlet (or JSP)
* Prefix path mapping, e.g. a /foo/* mapping directs all URIs starting with
/foo/ to the specified servlet (or JSP)
* Extension mapping, e.g. a *.foo mapping directs all URIs ending with .foo
to the specified servlet (or JSP).
* The default mapping, / sends all URIs not matched by one of the other
mappings the specified servlet (or JSP).
In other words, you can not use a pattern like "/foo/*.jsp", but you can use
"/foo/*" to let one servlet handle all requests starting with "/foo".
