title: JasperReports Server: HTML Component issue
body: <p>I have a report with HTML component in <em>JasperReports 5.1</em>. </p>
  
  <p>Its working fine in <em>iReport</em> but not working in <em>JasperReports Server Professional 5.0</em>.</p>
  
  <pre><code>org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found     starting with element 'hc:html'. 
  One of '{"http://jasperreports.sourceforge.net/jasperreports":component}' is expected.
  </code></pre>
  
  <p>I tried to add the following properties in <em>JasperReports.properties</em> file but it didn't work:</p>
  
  <pre><code>net.sf.jasperreports.extension.registry.factory.htmlelement=net.sf.jasperreports.extensions.HtmlElementExtensionsRegistryFactory
  
  net.sf.jasperreports.extension.registry.factory.htmlcomponent=net.sf.jasperreports.components.html.HtmlComponentExtensionsRegistryFactory
  </code></pre>
