Result of execution

If the block below is rendered by the HtmlRendererServlet instead of displaying the result of executing the above code, it probably means that the Sling - Scripting - Java Support bundle is not installed or not active. 

<% sling.include(currentNode.getPath(), "replaceSelectors=" + servlet.id + ", forceResourceType=javashell/" + servletFolderName); %>
