ClassNotFoundException DelegatingFilterProxy - eclipse

Question

I'm trying to perform some custom authentication using Spring security.
I've read a few things about it:

http://static.springsource.org/spring-security/site/
I also found an interesting conversation regarding this ClassNotFoundException DelegatingFilterProxy: http://forum.springsource.org/showthread.php?53972-Problem-when-finding-springSecurityFilterChain-bean
So, In my web.xml I have
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.0" 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_3_0.xsd">

</filter>
<filter-mapping>

<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
And in mysecuredapp-servlet.xml I have
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"

<beans:bean id="daoAuthenticationProvider" class="org.springframework.security.authentication.dao.DaoAuthenticationProvider" >

When I start tomcat (in Eclipse), I get this ClassNotFoundException DelegatingFilterProxy. Any idea why this is coming up?
Thanks in advance

Answer 1

This was a foolish error from myself... since I had issues for exact same reason: not including the Spring Dependencies to the Deployment Assembly.
See this answer I posted previously for more details: Maven + Spring + Dynamic Web Module ( Eclipse ) = java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

Answer 2

Is it possible that the filter chain isn't picking up your user details service bean? You dont seem to have a component-scan directive in your mysecuredapp-servlet.xml file, and the contextConfigLocation for the delegating filter only points to that file.
I could be wrong, but I'm fairly sure that the Spring context for the filter is separate to that for the dispatcher servlet. You'd need to either include a component-scan in your security XML file, or add you main Spring beans file to the contextConfigLocation.
