title: Error 500 in each xpage
body: <p>I am facing a strange error in xpages. Whenever i preview any xpage in internet explorer I get error 500. I've tried this with new nsf, I created only one blank xpage with no elements and tried to preview, I got the same error.
  I've also checked the "Display Xpages runtime error page" in xpages tab in Application Properties section but got the same 500 error.
  <strong>(I am working on my local machine)</strong></p>
  
  <p>Url of my xpage:</p>
  
  <pre><code>http://localhost/test/testdb.nsf/testxpage.xsp
  </code></pre>
  
  <p>For every preview attempt log.nsf has below entry</p>
  
  <pre><code>04/17/2012 03:24:10 PM  HTTP Web Server: Command Not Handled Exception [/test/testdb.nsf/testxpage.xsp] Anonymous
  </code></pre>
  
  <p>Below is the error on ie.</p>
