Given the URL:

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
entry-point-ref="authProcessFilterEn...
This is a skeleton implementation:
public class MyAuthenticationSuccessHandler implem...

Tomcat gzip compression filter can be turned on with " compression=on " in server.xml :
<Connector port="8080" protocol="HTTP/1.1"
...
The default compressed MIME types are: text/html,text/xml,text/plain .
It would be nice to add other types:
<Connector
port="8080"

The annotation @org.hibernate.annotations.Type overrides the default hibernate mapping type used for a column. This can usually be omitted since Hibernate normaly infers the correct type to use.
But @Type is required in ambiguous scenarios such as a java.util.Date attribute, which can map to SQL DATE , TIME or TIMESTAMP . You use the @Type("timestamp") annotation to tell Hibernate that a timestamp converter should be used, which identifies an instance of org.hibernate.type.TimestampType .
@Type can also be used to identify custom type converters, which can be defined with @TypeDef at the class level:
@TypeDefs(
{
@TypeDef(

This is a simple Hello World application with Spring 3 MVC. Like the default Apache HTTPd welcome page, it displays " It works! " when successfully deployed. The sole purpose is to show the minimum elements needed to setup Spring 3 MVC.
I use Maven since it's so much easier than downloading the dependencies manually.
Directory layout:
./src
./src/main
./src/main/webapp
./src/...

Our custom tag, as implemented in the previous note , is broken when a template is used.

Then request the page with URL: http://localhost:8080/facelet-demo/home.jsf?name=Jack .
You'll find that our hello tag works inside ui:repeat but fails to get the value defined by ui:param ! What's the problem? Our hello tag implementation evaluated the EL with the wrong EL context!
This is the corrected implementation:
package com.example;
