Coding a Quartz ActionJob

Code Block
titleActionJob.java
package com.trantek.sit.action;

import com.opensymphony.xwork.ActionProxy;
import com.opensymphony.xwork.ActionProxyFactory;
import com.opensymphony.xwork.interceptor.component.ComponentInterceptor;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import java.util.HashMap;

public class ActionJob implements Job
{
    public void execute(JobExecutionContext context) throws JobExecutionException
    {
        try
        {
            HashMap ctx = new HashMap();
            ctx.put(ActionContext.PARAMETERS, context.getJobDetail().getJobDataMap());
            ctx.put(ComponentInterceptor.COMPONENT_MANAGER, ???);
            ctx.put(???, ???)
            ServletDispatcher.createContextMap()
            ActionProxy proxy = ActionProxyFactory.getFactory().
                    createActionProxy("", context.getJobDetail().getName(), ctx);

            proxy.execute();
        }
        catch (Exception e)
        {
            throw new JobExecutionException(e);
        }
    }
}

...

  • The name of your job is the name of the Action to execute (no ".action" equivalent suffix).
  • All the parameters being sent to the Action are provided by the JobDataMap of the JobDetail object.
    Info

    According to the Javadocs of org.quartz.ee.servlet.QuartzInitializerServlet, the Quartz scheduler is setup as a servlet.
