The landing page after login can be configured with the default-target-url attribute of form-login . If a user was redirected to the login form after requesting a restricted URL, she's redirected to the original requested page after successful login.
An easy configuration looks like this:
<beans:beans xmlns="http://www.springframework.org...
But there are times that you want to do more initialization after login (such as loading user data), or apply more complex logic before redirecting. This is where the authentication-success-handler-ref attribute comes into play. You create a class that implements org.springframework.security.web.authentication.AuthenticationSuccessHandler and use that as the authentication-success-handler-ref :
<http

This is a skeleton implementation:
public class MyAuthenticationSuccessHandler implem...

This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty.

The error message is the title since no error message is specified. A more fully defined validation check would look like this:

there's no option in web.xml to exclude a more specific pattern such as: /public/* .
But you can put the exclusion logic in the filter itself:

The servlet API allows servlet filters to be inserted into the processing cycle to form a Filter Chain . How is a chain defined, and what is the ordering of filters in the chain?
The servlet filter chain is formed by defining multiple filters for the same servlet or URL pattern in web.xml . The order in which the filters are invoked is the same order as <filter-mapping> s appear in the web.xml file.
For example, if this is defined in web.xml :
<!-- Filter mapping -->
<filter-mapping>
...
then servletFilter2 will be applied before servletFilter .
Actually, it's more accurate to imagine these filters as layers or wraps instead of chains. In the above example, servletFilter2 wraps servletFilter .

If CSS3 border-image is properly supported, making a rounded corner box is very easy. You just need a round corner image like this: The following markup:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" ... would render like this (try it in Firefox 3.5 and Google Chrome): However, IE as of version 8.0 does not support border-image . So until border-image is reliably supported in all major browsers, we still have to rely on tried and true tricks to make it work. In general, I found three general categories of tricks to make rounded corners: Good old tables. This trick creates a table of 9 cells and uses the 8 cells on the perimeter to render the borders and rounded corners. The central cell is used for...

When rendering an HTML form, it is customary to use an icon to indicate that a field is required. You can render the icon in HTML directly, but it's a lot more convenient to use CSS. Here's the CSS:
