Thymeleaf template/ view not found - Spring 4

I'm setting up a new SPring4 app using Thymeleaf and keep encountering the same issue when it comes to returning the view. I've searched don here and followed some online tutorials but the same error so I'm thinking it may be due to configuration, any help is appreciated, thanks.
The error : org.thymeleaf.exceptions.TemplateInputException: Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers
And then my config is:

Let your spring dispatcher map your urls. So in your web.xml change your welcome-file to:
<welcome-file>/</welcome-file>
then in your controller add a mapping for index.
#RequestMapping(value = "/", method = RequestMethod.GET)
public String viewIndex() {
return "index";
}
And put your index.jsp inside your WEB-INF/jsp folder

Java Spring MVC project suddenly very slow

my spring project suddenly became very slow, both on startup and serving some kind of request.
I didn't change anything in the web.xml \ spring-context, but it all became very slow.
The startup passed from around 5 seconds to 30, the login serving demands around 15 seconds and in the console spring seems to do about nothing.
To be clearer as possible, this is the startup spring log:
http://pastebin.com/DezpJRJb
During the startup process it seems to be very slow on inner bean instantiation.
07/02/2015 10:58:02 - DEBUG - (AbstractBeanFactory.java:247) - Returning cached instance of singleton bean 'lastFmController'
In the spring-context.xml I declared the package to be scanned first when looking for a controller:
<context:component-scan base-package="org.fabrizio.lastfmmusicrecommender.controller" />
And until yesterday it all worked great, it seems something went wrong without reasons.
I also post web.xml \ spring-context.xml \ springmvc-servlet.xml

but .js file is not linked up, please give me a directions, thanks in advance!!!

I think you should put ${pageContext.servletContext.contextPath} and you should notice the name (and version ) declare in Spring-dispatcher-servlet.xml must same with the file in /js directory (jquery-1.6.2.js,jquery-1.11.1.js, jquery.js v.v...)
<script type="text/javascript" src="${pageContext.servletContext.contextPath}/js/jquery-1.6.2.js"></script>
and as everyone suggest, make sure you have
<mvc:resources mapping="/js/**" location="/js/" />
in Spring-dispatcher-servlet.xml
hope it work

Its not a very much spring way, but I could link a javascript file as below
<script type="text/javascript" src="/js/jquery-1.11.1.js" ></script>
Please check if it works for you also.!
