Project name: <your-project-name> Rest default settings
Download and unzip the latest Spring jar files from http://www.springsource.org/download/community?project=Spring%2520Framework
Copy the following files from the above unzipped folder into the Web/WEB-INF/lib folder:
org.springframework.asm-3.x.x.RELEASE-x.jar org.springframework.beans-3. x.x.RELEASE-x.jar org.springframework.context-3. x.x.RELEASE-x.jar org.springframework.core-3. x.x.RELEASE-x.jar org.springframework.expression-3. x.x.RELEASE-x.jar org.springframework.web.servlet-3. x.x.RELEASE-x.jar org.springframework.web-3. x.x.RELEASE-x.jar

WEB-INF/web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>Spring ACL Demo</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- For issues with multiple apps on tomcat --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springacldemo_root</param-value> </context-param> <!-- MVC application controller.

Create our welcome file – index.jsp as defined in web.xml under <welcome-file-list> tag:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Spring ACL Demo Index page</title> </head> <body> <a href="hello.htm">Say Hello</a> </body> </html>
———————————————————————
Create our hello file – hello.jsp linked from index.jsp as hello.htm:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Spring ACL Demo Hello page</title>
</head>
<body>${message}
</body>
</html>

Create WEB-INF/springacldemo-servlet.xml. Spring knows to look for this file because of “springacldemo” in servlet-name. The servlet class is defined in <servlet-name>-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <!-- This configuration will take any url request that matches *.htm pattern and map it to file with the same name but with a .jsp extension using the UrlFilenameViewController and InternalResourceViewResolver provided by spring. --> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <value> /*.htm=urlController </value> </property> </bean> <bean id="urlController" class="org.springframework.web.servlet.mvc.UrlFilenameViewController" /> <!-- Because of the viewResolver, we do not have to specify our internal structure. --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>

Create build.xml
<project name="Spring ACL Demo" default="war" basedir=".">
<property name="app.name" value="springacldemo" />
<property name="app.path" value="/${app.name}" />

</project>

Use terminal to go the root of the project, and type:
ant deploy
This will deploy the web application to the tomcat server and available at http://localhost:8080/springacldemo
The error logs will be available at
$CATALINA_HOME/logs/Catalina.out and $CATALINA_HOME/logs/localhost.yyyy-mm-dd.log
