title: java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener issue
body: <p>when I try to start my app, console shows the next stacktrace:</p>
  
  <pre><code>java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
  </code></pre>
  
  <p>I've read about the same problem, but ther were absent spring-web jars, but in my pom.xml I've included spring dependencies, the problem stays:</p>
  
  <pre><code>         &lt;dependency&gt;
              &lt;groupId&gt;org.springframework&lt;/groupId&gt;
              &lt;artifactId&gt;spring-web&lt;/artifactId&gt;
              &lt;version&gt;${spring.version}&lt;/version&gt;
          &lt;/dependency&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;org.springframework&lt;/groupId&gt;
              &lt;artifactId&gt;spring-webmvc&lt;/artifactId&gt;
              &lt;version&gt;${spring.version}&lt;/version&gt;
          &lt;/dependency&gt;
  </code></pre>
  
  <p>here is web.xml file(just to be sure):</p>
  
  <pre><code>&lt;context-param&gt;
          &lt;param-name&gt;contextConfigLocation&lt;/param-name&gt;

  <p>I made clean.., clean tomcat work directory..., I cleaned workspace with project->clean.. but nothing helped.. I'm in a such desperation...</p>
  
  <p>updated=============
  after some manipulation and magic :) I succeeded not to have such exception, but the next appears:</p>
  
  <pre><code>java.lang.ClassCastException: org.springframework.web.filter.DelegatingFilterProxy cannot be cast to javax.servlet.Filter
  </code></pre>
