All Implemented Interfaces:

public class CmsPdfResourceHandler
extends Object
implements I_CmsResourceInit

This resource handler handles URLs of the form /pdflink/{locale}/{formatter-id}/{detailname} and format the content identified by detailname using the JSP identified by formatter-id to generate XHTML which is then converted to PDF and returned directly by this handler.
