web.xml

<?xml version="1.0" encoding="UTF-8"?>

</servlet-mapping>
<welcome-file-list>

</welcome-file-list>
</web-app>

spring-security.xml

<beans:beans xmlns="http://www.springframework.org/schema/security"

<intercept-url pattern="/welcome*" access="ROLE_USER" />
</http>

<authentication-manager>
<authentication-provider>
<user-service>
<user name="admin" password="admin" authorities="ROLE_USER" />

Please use [ code][/code ] tags when posting code, that way it remains readable...

Have you read the stacktrace?

java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

You are missing the aopalliance.jar ...

I suggest you start using maven, ant+Ivy or gradle (or whatever dependency management tool you want to use) to manage your dependencies. Saves you a lot of searching the internet for jar files and getting compatible versions.
