Question

Please help with the following error that I get with Spring Security 3.05 and Tomcat7.0. I am new to spring security and am using the below tutorial:
Simple web application with Spring Security: http://heraclitusonsoftware.wordpress.com/software-development/spring/simple-web-application-with-spring-security-part-6/

Here is the error:

Answer 1

org.springframework.security.userdetails.UserDetailsService is from Spring Security 2.x, in Spring Security 3.x its name is org.springframework.security.core.userdetails.UserDetailsService.

So, you have some Spring Security 2.x jars in the classpath.
