How is your XML file referencing the schema?

[picosam]

<beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="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.xsd
		http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd">

There you go!

is the spring-security-config-3.0.0.M2.jar in your classpath?

[picosam]

Yes of course, it had been downloaded by maven and put into my WEB-INF/lib folder as normal.

The problem was due to AntUrlPathMatcher not being found.
I included spring-security-web package which solved the problem.
