I found that by placing a direct jsp mapping to Tomcat's JSP servlet, I could
accomplish what I needed, so long as the URL is longer than the catch-all
mapping as per the servlet spec.
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>/views/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>controller</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
