Initialization of bean failed when creating a Camel context in Spring

I am having trouble creating a plain Camel context in a web application using Spring. I've created a new maven project and deleted my maven repositories before recreating the issue. The only files in the project apart from the ones added by Maven are InitialContext.xml, web.xml and pom.xml. The initial context file looks like:

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    version="2.5" 
    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_2_5.xsd">

    <display-name>CamelSpring</display-name>

    <context-param>
        <param-name>
            contextConfigLocation
        </param-name>
        <param-value>
            /WEB-INF/InitialContext.xml
        </param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

</web-app>

InitialContext.xml

I get an error which looks like:

I've been looking around but I can't find anything that suggests what is wrong with this set up. I'm hoping its just something that I have not added to the pom. Does anyone have any ideas as to how to fix this?

After changing the version in pom.xml, the error got resolved.

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-core</artifactId>
    <version>3.0.0-M2</version>
</dependency>

This usually happens due to different versions of spring modules being used. Using same version for all spring dependencies including the ones in xsd should help.
