Answer 1

You are mixing Spring versions and you are mixing Spring Security Versions (3.1.3 and 3.1.4), Spring Security 3.1 has a dependency on Spring 3.0 whereas you are trying to use 3.1. Spring WS 2.1 depends on Spring 3.2... So you have a whole mixture going on.

I would suggest upgrading to Spring 3.2.4 (the latest version) and use a properties element to determine the version instead of specifing it for each dependency. Next to that I also suggest using tag to force dependencies on a certain version. And finally (or maybe firstly) I suggest the use of the maven-enforcer-plugin with a dependency convergence rule, this will break the build if there are conflicting versions of certain dependencies.

Enforcer plugin

   
       
            org.apache.maven.plugins
            maven-enforcer-plugin
            1.3.1
            
                
                    enforce-banned-dependencies
                    
                        enforce
                    
                    
                        
                            
                            
                                true
                                
                                    commons-logging:commons-logging
                                    org.slf4j:slf4j-simple
                                
                            
                        
                        true
                    
                
            
        
        

Use Properties

    3.2.4.RELEASE
    3.1.4.RELEASE
    2.1.3.RELEASE



    
        org.springframework.security
        spring-security-web
    
    
        org.springframework.security
        spring-security-config
    

Use Dependency Management

    
        
        
            org.springframework
            spring-aop
            ${spring-framework.version}
        
        
            org.springframework
            spring-aspects
            ${spring-framework.version}
        
        
            org.springframework
            spring-beans
            ${spring-framework.version}
        
        
            org.springframework
            spring-context
            ${spring-framework.version}
        
        
            org.springframework
            spring-context-support
            ${spring-framework.version}
        
        
            org.springframework
            spring-core
            ${spring-framework.version}
            
                
                    commons-logging
                    commons-logging
                
            
        
        
            org.springframework
            spring-expression
            ${spring-framework.version}
        
        
            org.springframework
            spring-jdbc
            ${spring.version}
        
        
            org.springframework
            spring-jms
            ${spring-framework.version}
            
                
                    commons-logging
                    commons-logging
                
            
        
        
            org.springframework
            spring-orm
            ${spring-framework.version}
        
        
            org.springframework
            spring-oxm
            ${spring-framework.version}
        
        
            org.springframework
            spring-tx
            ${spring-framework.version}
        
        
            org.springframework
            spring-web
            ${spring-framework.version}
        
        
            org.springframework
            spring-webmvc
            ${spring-framework.version}
        
        
    
    org.springframework.security
    spring-security-web
    ${spring-security.version}
    
    
    org.springframework.security
    spring-security-config
    ${spring-security.version}
    
        
        
            org.springframework.ws
            spring-ws-core
            ${spring-ws.version}
            
                
                    commons-logging
                    commons-logging
                
            
        
        
            org.springframework.ws
            spring-ws-support
            ${spring-ws.version}
            
                
                    commons-logging
                    commons-logging
                
            
        

When you use this you can ommit the version number in de section.

This xml excludes commons-logging because we don't use that we use SLF4J with the jcl-over-slf4j wrapper jar. If you want to use commons-logging simply remove the exclusions and rule from the enforcer plugin.
