All Implemented Interfaces:

Serializable, Servlet, ServletConfig

public class PlaceholderPreviewServlet

extends HttpServlet

A servlet which generates a content query preview info.

If a request parameter called 'query' is set, it is assumed to contain the cq:contentQuery XML structure of a content query. The 'username' request parameter will be used to resolve user property references. The servlet will return XML of the form:

 <preview-info-result>
   <preview-info is-folder="true|false">
      <path>...</path>
      <mimeType>...</mimeType>
      <size>...</size>
   </preview-info>
   ...
 </preview-info-result>
 

with a <preview-info> entry per content object that would be returned from the content query.

If a request parameter of 'path' is set, then, depending upon the 'phtype' request parameter, the corresponding content object will be rendered (Ad) or displayed (ContentSelector).

The phType request parameter is always required

This expects the PlaceholderService to use to be mapped to java:comp/env/ejb/PlaceholderService and the AdServier to be mapped to java:comp/env/ejb/AdService.

It also expects a ShowBinaryServlet to mapped to the partial URI defined by the "ShowDocURI" init parameter (defaulting to ContentProviders.getShowDocURI()).
