title: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict
body: <pre><code>org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'drools:grid-node'. 
  </code></pre>
  
  <p>I'm getting this error when I add a grid-node and ksession to my spring xml. I did some searching and looks like it a classpath issue. What dependency am I missing here ? </p>
