History.js gracefully supports the HTML5 History/State APIs (pushState, replaceState, onPopState) in all browsers. For HTML4 browsers it will revert back to using the old onhashchange functionality. All major browsers are supported.
This is a simple test page to get started:
<html>
<head>
<title>Test History</title>
...
Note: state url must be provided for IE to generate a unique hash. YOu can prefix the state url with '?' ('#' does not work).

The default servlet for Tomcat is declared in $CATALINA_HOME/conf/web.xml :

Therefore, static content is rendered by the default configuration unless you override it with your own definitions.
If you want to allow directory listing, just change the listing parameter to true :

Welcome pages are defined at the Web application level.

Spring MVC 3.1 can send either JSON or HTML response on the same URL, depending on the type of response requested. With this mechanism, a page can be sent when directly requested from a link, but a JSON response can be sent in response to an AJAX request. This is the controller code:
package com.example; import java.util.Map; ... In the above example, JSON response will be sent when the HTTP request contains header "Accept: application/json". HTML response will be sent then the header is "Accept: */*", or "Accept: text/html", or anything else. You can add a limitation that the HTML response does not produce "application/json". But then the question is which response will be sent when the HTTP header is "Accept: */*"? Both methods will...

1. mvc:default-servlet-handler Configures a handler for serving static resources by forwarding to the Servlet container's default Servlet. Use of this handler allows using a "/" mapping with the DispatcherServlet while still utilizing the Servlet container to serve static resources. HandlerMapping: org.springframework.web.servlet.handler.SimpleUrlHandlerMapping Handler: org.springframework.web.servlet.handler.SimpleUrlHandlerMapping Attribute Description default-servlet-name The name of the default Servlet to forward to for static resource requests. The handler will try to auto-detect the container's default Servlet at startup time using a list of known names. If the default Servlet cannot be detected because of using an unknown container or because it has been manually configured, the servlet name must be set explicitly. 2. mvc:view-controller Defines a simple Controller that selects a view to render the response. HandlerMapping: org.springframework.web.servlet.handler.SimpleUrlHandlerMapping Handler: org.springframework.web.servlet.mvc.ParameterizableViewController Attribute Description...

In my JSP there's a link like this:
<a href="/path/${part1}/${part2}">the link</a>
where part1 and part2 may contain characters that need to be URL encoded (such as '#').
JSP JSTL does not provide such facility out of the box. But there's a hack using <c:url> , or you can use <spring:url> :
JSTL hack:
<c:url value="/path" var="theUrl">
<c:param...
Using Spring url tag:
<spring:url value="/path/{part1}/{part2}" var="enc...
