Did you know you can schedule jobs in portal using KM's Scheduler Task?

[Former Member]

Introduction

Last year I wrote a scheduler for running jobs in portal. A month later I found out that KM already provides a very good api for scheduling jobs which can run periodically. You can write any kind of job that can be executed via JAVA.Please don't think the job only runs for KM stuff. I am currently using this scheduler task to extract BW data in xml format and store it in KM. So, in this weblog i am going to present a help guide for creating KM's scheduler task for running jobs periodically.

The following steps will guide you in creating KM's scheduler task for Portal

Step 1:

Create an empty project

Step 2:

Using the KM Scheduler Task Wizard, create a empty template for your job.

Click on Next

Fill out the above screen and click on Finish.

Step 3

Navigate in your project structure (under src.api folder) to find you java class file extract.java or whatever you have defined the class name in the wizard. You will find the following template already created by NWDS.

package com.ust.yahooxmlfeed;import java.util.Properties;import com.sapportals.wcm.WcmException;import com.sapportals.wcm.service.*;import com.sapportals.wcm.service.scheduler.*;public class extract implements ISchedulerTask {  public void run( String id, Properties properties ) { // implement the tasks to be scheduled  }}

Step 4

Modify the code to do whatever task you want the class to perform. In my case i am going to grab a yahoo's world news rss feed and store it in KM.

package com.ust.yahooxmlfeed;import java.net.URL;import java.util.Properties;import com.sapportals.portal.security.usermanagement.IUser;import com.sapportals.wcm.repository.Content;import com.sapportals.wcm.repository.ICollection;import com.sapportals.wcm.repository.IResourceFactory;import com.sapportals.wcm.repository.ResourceContext;import com.sapportals.wcm.repository.ResourceFactory;import com.sapportals.wcm.service.scheduler.ISchedulerTask;import com.sapportals.wcm.util.uri.RID;import com.sapportals.wcm.util.usermanagement.WPUMFactory;public class extract implements ISchedulerTask {  public void run( String id, Properties properties ) { // implement the tasks to be scheduled   try {    RID aRid = RID.getRID("/documents");    IUser user =     WPUMFactory.getServiceUserFactory().getServiceUser(      "cmadmin_service");    ResourceContext ctxt = new ResourceContext(user);    //  get an instance of a resource factory    IResourceFactory aResourceFactory = ResourceFactory.getInstance();    // retrieve a collection with context    ICollection aCollection =     (ICollection) aResourceFactory.getResource(aRid, ctxt);    //save the yahoo feed to a file    URL urlpage =     new URL("http://rss.news.yahoo.com/rss/world");    Content aContent =     new Content(urlpage.openStream(), "txt/xml", -1L);            //check to see if the file is there. If it is there then update it.             //Otherwise create it     if (!aResourceFactory     .checkExistence(      RID.getRID("/documents/yahoofeed.xml"),      ctxt))     aCollection.createResource(      "yahoofeed.xml",      null,      aContent);    else {     aResourceFactory      .getResource(       RID.getRID("/documents/yahoofeed.xml"),       ctxt)      .updateContent(aContent);    }    aContent.close();   } catch (Exception e){e.printStackTrace();   }  }}

Step 5:

Build your component and deploy your par and then navigate to following location.
System Administration->System Configuration->Knowledge Management->Configuration->Content Management->Global Services->Scheduler Tasks

Step 6:

You will see your task. Click on it and schedule it to run at a particular time. You can define new periodic times as well.

Click your task(in my case it is com.ust.yahooxmlfeed.extract) and then click on edit


Select the time you want to schedule and then click on Apply and OK. In my case i am runing it 50 minutes past every hour

BAM! you got yourself a job that runs periodically
