OpenCms Development : OpenCms Development Development in OpenCms requires knowledge in HTML Basic XML SQL (JDBC) OpenCms XML Template API OpenCms Java API Development in general is separated in 'Core' and 'Module' development Development on a project is usually 'Module' development. These modules are managed with the workplace.


Core class architecture : Core class architecture Servlet Engine (e.g. Tomcat) CmsServlet com.opencms.boot OpenCmsHttpServlet com.opencms.core OpenCms com.opencms.core CmsObject com.opencms.file System Initialization Request Authorizing CmsUser CmsGroup com.opencms.file CmsFile CmsFolder com.opencms.file (other Resources) Resources manipulated with CmsObject


Page access & delivery : Page access andamp; delivery URL: http://server.name.com/opencms/opencms/somdir/somepage.html Server ID Servlet context (requred by Tomcat) Handled to the servlet as a parameter CmsObject will be created with requesting users permission (or 'Guest' if not identified) CmsObject will try to access the requested resource (i.e. /somedir/somepage.html) If sufficient permissions are available, resource will be processed according to the resource type Output of the process is delivered back to user


OpenCms Template mechanism : OpenCms Template mechanism The most common requested resource type is 'page' Pages are constructed from several elements and sub-elements OpenCms uses a template mechanism based on XML (Xerces parser) to build the pages from the elements Dynamic functionality is created by writing Java classes that extend com.opencms.template.CmsXmlTemplate The Template mechanism features sophisticated caching and static export of pages


Static Export & “Backlink” : Static Export andamp; 'Backlink' Pages in 'News' contain only static information Page 'Form' is part of a dynamic application Page 'Account' is dynamic and requires https security OpenCms 4.6: Manages all 3 Servers with different URLs on one set of templates, automatically insuring consistent Links All 3 Pages should be based on the same templates
