title: ClassNotFoundException error in apache karaf
body: <p>I added <code>contect-param</code> tab in the <code>web.xml</code> file</p>
  
  <pre><code>&lt;context-param&gt;
      &lt;param-name&gt;blueprintLocation&lt;/param-name&gt;
      &lt;param-value&gt;OSGI-INF/blueprint/blueprint.xml&lt;/param-value&gt;
  &lt;/context-param&gt;
  </code></pre>
  
  <p>also <code>listner</code> class in the <code>web.xml</code> file</p>
  
  <pre><code>&lt;listener&gt;
      &lt;listener-class&gt;org.apache.aries.blueprint.web.BlueprintContextListener&lt;/listener-class&gt;
  &lt;/listener&gt;
  </code></pre>
  
  <p>after loading to karaf, I am getting the error below:</p>
  
  <blockquote>
    <p>java.lang.ClassNotFoundException: org.apache.aries.blueprint.web.BlueprintContextListener not found by com.test.test.core.jsonstore-http-api</p>
  </blockquote>
