title: Navigation Engine not able to process request
body: <p>I get the following error in Endeca:</p>
  
  <pre><code>com.endeca.navigation.ENEException: Navigation Engine not able to process 
  request `http://myhost:15000/search?terms=remote&amp;rank=0&amp;offset=0&amp;irversion=601`
  </code></pre>
  
  <p>My MDEX version is 6.3.0</p>
  
  <p>The referenced jar files in my app is:</p>
  
  <p><code>endeca_navigation.jar</code> : Specification-IR-Version: 6.3.0 (Read from MANIFEST file)
  <code>endeca_logging.jar</code>: Specification-Version: 6.1.2 (Read from MANIFEST file)</p>
  
  <p>Even with these referenced jars, why is the request parameter still <code>irversion=601</code>?
  I'm using java 1.5 and building my app in eclipse. At first, it was referencing older jar files (601), but i removed those completely and replaced them with the newer jar files listed above. I've rebuilt my app and I still see the parameter irversion=601. I've been trying to find out what the issue is for a few hours, but i'm having no luck.</p>
  
  <p>Any ideas?</p>
