Your HTML is wrong! It has a closing <body> and <html> tag in you "main-content (index.jsp)"!
You have your template: classic.jsp and you include index.jsp in the <tiles:insertAttribute name="body" /> placeholder. So the resulting HTML would looks like, (the complete index.jsp will be inserted at the placeholder!):
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>...</title>
</head>
<body>
<html> <!-- problem starts her -->
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO8859-1">
<title>Insert title here</title>
</head>
<body>
<p>index page</p>
</body> <!-- that is the reason for not -->
</html> <!-- having a footer -->
<br>

</body>
</html>
Did you noticed that you "close" the html content with </body> and </html> already before the footer! -- The solution is simple: remove all the header, html and body tags from index.jsp:
<%@ 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">
<p>index page</p>
An other point:
Remove your InternalResourceViewResolver from the configuration. The problem is that you have two view resolvers (Internal and Url/Tiles) and it is likely that your viewname (return "index") is resolved by the Internal view resolver, but not by the Url/Tiles resolver.
According to Spring Reference, Chapter 18.3.2 Integration Tiles, you just need:
org.springframework.web.servlet.view.tiles3.TilesConfigurerorg.springframework.web.servlet.view.UrlBasedViewResolver with TilesView configured for viewClass property (or use org.springframework.web.servlet.view.tiles3.TilesViewResolver - that is an anready configured subclass of UrlBasedViewResolver)
org.springframework.web.servlet.view.ResourceBundleViewResolverexample:
<bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/defs/general.xml</value>
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver" id="tilesViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"/>
</bean>
