I'm trying to create Spring web application with annotations only(no configuration xml files). I am using tomcat as application server and maven for build the project. Googled a lot, modified a lot but still stuck with this error. Please find below the files. Hope some one can help me. Thanks in advance. :)
Below is the pom.xml

Your web.xml is wrong. You want to use a ServletContainerInitializer (the one provided by Spring) which is part of the servlet spec 3.0. However your web.xml makes the container operate in a 2.3 mode. Fix your web.xml.

Next, although not directly related but you will run into problems soon enough, you are mixing different versions of the Spring Framework. Never mix jars from different versions of a framework (not only spring but all frameworks). Tip use a single property to define the version you want to use.

I took the liberty to cleanup the pom and upgrade to the newest 3.2 version of Spring.

Add the below tag to your web.xml, include it inside the web-app tag
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
