Create a Custom Scheduled Job

A scheduled job is a bit of code that is run on a regular basis by OpenCms. You can create custom scheduled jobs by creating a java class that implements I_CmsScheduledJob. OpenCms itself comes with some classes that do so, like CmsPublishJob.

Then you add your Java class to OpenCms. You can either create a jar file, or a class file. Then you add them to your OpenCms installation - your options are on the Adding_Jar_Files page.

Follows an example of a JSP that gets its parameters from request and does the scheduling, found at this Nabble thread [1]:

<%@page import="org.opencms.main.CmsContextInfo,
                        org.opencms.scheduler.CmsScheduledJobInfo,
                        org.opencms.scheduler.CmsScheduleManager,
                        org.opencms.file.CmsObject,
                        org.opencms.jsp.CmsJspBean,
                        java.util.SortedMap,
                        java.util.TreeMap"%>

CmsScheduledJobInfo csji = new CmsScheduledJobInfo();
CmsScheduleManager csm = new CmsScheduleManager();
CmsJspBean cjb = new CmsJspBean();
 
cjb.init(pageContext,request,response);
 
CmsObject cmsObj = cjb.getCmsObject();
CmsContextInfo cci = new CmsContextInfo(cjb.getRequestContext());

SortedMap parametros = new TreeMap();
parametros.put("request",request);
parametros.put("response",response);
 
csji.setParameters(parametros);
csm.initialize(cmsObj);
 
csm.scheduleJob(cmsObj,csji);
