title: Adding Apache Shiro parameters into web.xml unables correct app deployment
body: <p>I have been trying to use Apache Shiro in my java web project but I have read all the tutorials and examples to no avail. My app was running okay until I created the web.xml file and included the following lines:</p>
  
  <pre><code>&lt;listener&gt;
   &lt;listener-class&gt;org.apache.shiro.web.env.EnvironmentLoaderListener&lt;/listener-class&gt;
  &lt;/listener&gt;
  
  &lt;filter&gt;
   &lt;filter-name&gt;ShiroFilter&lt;/filter-name&gt;
   &lt;filter-class&gt;org.apache.shiro.web.servlet.ShiroFilter&lt;/filter-class&gt;
  &lt;/filter&gt;
  
  &lt;filter-mapping&gt;
   &lt;filter-name&gt;ShiroFilter&lt;/filter-name&gt;
   &lt;url-pattern&gt;/*&lt;/url-pattern&gt;
   &lt;dispatcher&gt;REQUEST&lt;/dispatcher&gt;
   &lt;dispatcher&gt;FORWARD&lt;/dispatcher&gt;
   &lt;dispatcher&gt;INCLUDE&lt;/dispatcher&gt;
   &lt;dispatcher&gt;ERROR&lt;/dispatcher&gt;
  &lt;/filter-mapping&gt;
  </code></pre>
  
  <p>Also, I am using Netbeans as IDE and not using Maven because I don't know how to use it, I did try to follow the tutorials with a simple Maven proyect, though. I would like to hear a solution with no Maven in it please.</p>
  
  <p>For more information about my proyect structure, here it is.</p>
  
  <p>NetBeans 8.0
  Java Web Application</p>
  
  <p>Libraries under WEB-INF/lib/
  shiro-core-1.2.3.jar
  shiro-web-1.2.3.jar
  slf4j-simple-1.7.2.jar</p>
  
  <p>Those are included using the Netbeans include libraries.</p>
  
  <p>I would like some guidance over this because I have not found pretty much information on using Shiro without Maven. Thank you in advance.</p>
