title: Failed to read schema document of spring.security
body: <p>My spring-security.xml is</p>

  <p>When I start the server (Tomcat 7) inside Eclipse I get this error:</p>
  
  <blockquote>
    <p>Ignored XML validation warning org.xml.sax.SAXParseException:
    schema_reference.4: Failed to read schema document
    '<a href="http://www.springframework.org/schema/security/spring-security-3.2.xsd" rel="nofollow">http://www.springframework.org/schema/security/spring-security-3.2.xsd</a>',
    because 1) could not find the document; 2) the document could not be
    read; 3) the root element of the document is not .</p>
  </blockquote>
  
  <p>The libraries I've imported are:</p>
  
  <p>commons-logging</p>
  
  <ul>
  <li>jsp</li>
  <li>jstl</li>
  <li>spring-aop-4.0.4</li>
  <li>spring-beans-4.0.4</li>
  <li>spring-context-4.0.4</li>
  <li>spring-core-4.0.4</li>
  <li>spring-expression-4.0.4</li>
  <li>sprig-web-4.0.4</li>
  <li>spring-webmvc-4.0.4</li>
  <li>spring-security-core-3.2.4</li>
  </ul>
  
  <p>I believe there are some problems with the library version, but I'm not sure.
  I tried to search the version 4.0.4 but I haven't found it. </p>
  
  <p>Is the spring-security library included in another one? If yes, where can I look into when I need to know the unifications between the spring versions?</p>
  
  <p>How can I solve the error?</p>
  
  <p>I googled all my questions but I haven't found anything.</p>
