this entry
<servlet-mapping> <servlet-name>faces servlet</servlet-name> <url-pattern>*.jsp</url-pattern> </servlet-mapping> is causing facesservlet run in infinite loop because jsf delegate jsp servlet when resolving views, you've mapped facesservlet listen on same url pattern servletcontainer's builtin jsp servlet!
replace more jsf-specific url pattern such *.jsf
<servlet-mapping> <servlet-name>faces servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> and change jsf request urls end *.jsf instead.
unrelated concrete problem, form not utilizing jsf tags , managed bean bindings. wonder how jsf configuration relevant you. might want spend time in learning jsf first.
