Castle.Components.Scheduling-Tutorial

Jeff Brown recently contributed the new Scheduler component to the CastleContrib project. This is a great component but it needs some documentation. Recently he put out some instructions in the usergroup and I thought it would be nice to put it here.

To get this thing up and running you must follow the following steps:

First you need to run the scripts in the Castle.Components.Scheduler.Db directory create the test database and the store procedures.

After that you need to implement the IJob class. Here is a dummy one I used to test out the component:

using System;
using Castle.Components.Scheduler;
namespace ClassLibrary1
{
 public class MyJob: IJob
 {
  public bool Execute(JobExecutionContext context)
  {
   Console.WriteLine("Hello World - " + DateTime.Now.ToShortTimeString());
   return true;
  }
 }
}

And then you need to configure your Windsor configuration to look something like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
 <configSections>
  <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
 </configSections>
 <castle>
  <components>
   <component id="Core.Scheduling.Scheduler"
        service="Castle.Components.Scheduler.IScheduler, Castle.Components.Scheduler"
        type="Castle.Components.Scheduler.DefaultScheduler, Castle.Components.Scheduler" />
   <component id="Core.Scheduling.JobStore" service="Castle.Components.Scheduler.JobStores.IJobStore, Castle.Components.Scheduler"
     type="Castle.Components.Scheduler.JobStores.SqlServerJobStore, Castle.Components.Scheduler">
    <parameters>
     <connectionString>Server=(local);Initial Catalog=schedulerTestDb;Integrated Security=SSPI</connectionString>
    </parameters>
   </component>

   <component id="Core.Scheduling.JobRunner" service="Castle.Components.Scheduler.IJobRunner, Castle.Components.Scheduler"
     type="Castle.Components.Scheduler.DefaultJobRunner, Castle.Components.Scheduler" />

   <component id="Core.Scheduling.JobFactory" service="Castle.Components.Scheduler.IJobFactory, Castle.Components.Scheduler"
    type="Castle.Components.Scheduler.WindsorExtension.WindsorJobFactory, Castle.Components.Scheduler.WindsorExtension" />
   <component id="MyJob" service="Castle.Components.Scheduler.IJob, Castle.Components.Scheduler" type="ClassLibrary1.MyJob, ClassLibrary1" />
  </components>
 </castle>
</configuration>

And now you are ready to start the scheduler

namespace WindowsApplication1
{
 public partial class Form1 : Form
 {
  public Form1()
  {
   InitializeComponent();
  }
  protected WindsorContainer container;
  private void button1_Click(object sender, EventArgs e)
  {
   container = new WindsorContainer(new XmlInterpreter());
   IScheduler scheduler = (IScheduler)container["Core.Scheduling.Scheduler"];
   Trigger trigger = new PeriodicTrigger(new DateTime(1900, 1, 1), new DateTime(2900, 1, 1), new TimeSpan(0, 0, 10), 1000);
   JobSpec jobSpec = new JobSpec("My job.", "A test job.", "MyJob", trigger);
   scheduler.CreateJob(jobSpec, CreateJobConflictAction.Ignore);
   scheduler.Start();
  }
 }
}

Now you are done...you need to check the output for the result.
