Tomcat7 deploy Fail: org.apache.catalina.LifecycleException: Failed to start component /w org.springframework.web.servlet.DispatcherServlet

I have a very sample web.xml written below:

The problem is...If I remove org.springframework.web.servlet.DispatcherServlet section, I can successfully deploy my project in Tomcat7 as a simple JSP-Servlet app. However, once I use Spring MVC, my deployment will FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/WebMVCProj2]]

How can I fix this error?

I add Spring MVC dependency from Enterprise Bundle Repository (EBR). I also use Eclipse Dynamic Web Module 3.0 which Tomcat7 should support. My jre is 1.6.x 64bits used by Tomcat and my project. I also use Web Deployment Assembly in Eclipse.

Here is my complete exception:

Solution

  • You should have applicationContext.xml in web-inf folder or you have to define contextConfigLocation in your web.xml

    <!-- Spring Context -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:/application-contexts/*.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

    It would be more helpful, if you could post exception trace.
