Scheduler
hi All I want to implement a scheduler program something at the starting of the application or at the starting of tomcat. Basically i need one of my program to track all of the reminders i have set in an web-application. Say if i have set a reminder to send an email to client at 1400 hrs then it should send that email at that time without the need of signing into the account. Any help will be of great use. Thanks Gary
Re: Scheduler
Hi Gurpreet I haven't tried this...but it came across my mind as I need something similar very soon. You could write a Struts plugin... init() method called on start of webapp and destroy() method called on shutdown of webapp. In the init() method you could start a thread that "wakes up" at specified interval, say each minute, to check if there is some tasks that need to be done, eg sending mails, cleaning up, make some coffee (;-)) In the destroy method you could stop the thread again I don't know if this violates with the J2EE spec...I remember reading something about threads...but that might be for EJBs only...Anyone can shed some light on this issue?

Hi All, we are using a simple servlet which acts as a scheduler. in its init() we get the at what time to execute from props file and call java.util.Timer.schedule() in it.the schedule() takes an object(which implements java.util.TimerTask) as parameter regards srinivas - Do you Yahoo!?

Seems like the easiest way might be to write a JMX MBean and deploy that thing in a J2EE server, like JBoss.

Hi all, In my opinion, an application that should do the job you specified has nothing to do with struts.

RE: Scheduler
I agree, leave all the web specific stuff out of it. I wrote a little program that ran on a timer and broke it down into two simple classes. One class does the actual work, the other class wraps the first one and implements the Struts Plug-In and Runnable interfaces. Simple, easy. Putting the business logic into a non-web related object makes it reusable and malleable. The wrapper class is simply used as an invocation mechanism by the web container that calls the first object (which is the real program). I don't think I could have made it any simpler. http://www.c2.com/cgi/wiki?DoTheSimplestThingThatCouldPossiblyWork -Original Message- From: EL AKARI Mehdi [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 02, 2003 9:07 AM To: Struts Users Mailing List Subject: Re: Scheduler Hi all, In my opinion, an application that should do the job you specified has nothing to do with struts.

PlugIn Scheduler
hi
I have created the following plug-in and using it into my application. The problem
which I am facing is when I am running tomcat. The plug -in is not starting. The basic
idea behind this plugin is to start a thread and peform some logic after some interval
of time.
ANy suggestions will be of great help.
Following is the code for Plugin Class and the struts-config.xml
PlugTest.java
package efit;
import java.io.PrintStream;
import javax.servlet.ServletException;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.action.PlugIn;
import org.apache.struts.config.ApplicationConfig;
public class PluginTest
implements PlugIn, Runnable
{
public PluginTest()
{
t = null;
}
public void init(ActionServlet servlet, ApplicationConfig applicationConfig)
throws ServletException
{
System.out.println("The Plugin is starting");
t = new Thread(this);
t.start();
}
public void destroy()
{
System.err.println("\u2212\u2212\u2212\u2212>The Plugin is
stopping<\u2212\u2212\u2212\u2212");
}
public void run()
{
do
{
System.out.println("Plugin is Running");
try
{
Thread.sleep(1000L);
}
catch(Exception t)
{
System.out.println("Exception in Thread" + t.getMessage());
}
} while(true);
}
Thread t;
}

Huh,
I don't know if managing your own Thread is recommended by container. Is
there another way around this? Like JMX or implement the service action and
have a Demom periodically ping that service action to execute the intense
action?

how to reuse beans? You should be making your beans without any thought of the web whatsoever. THEN your Actions can calls your beans. This way, the Actions are clients of your API. By having an API containing business logic (instead of business logic in your actions), you promote reuse. An additional benefit of this type of bean design is that you can test it automatedly (JUnit!) without having Tomcat or servlet container running.

Re: designing simple scheduler
No, no that is not what we are saying. Just call the beans from your UI. In this case your UI is console. Same bean that you allready tested. Struts is the fastest way to develop that I know (15 years of IT for me) So your console app check the JavaMail and saves it or send it from db. Same beans and DB struts uses. So any mail shows up online. Batch/async is bread and butter of DP. Online is just the icing. .V Voinea, Marina wrote: yes, calling APP layer API (beans) from the UI is OK.

"Online is just the icing." Right! The business logic of the application should be UI agnostic. The logic shouldn't know if it was invoked from a console application, a Swing gui app, or a web (Struts!) application.

RE: designing simple scheduler
This probably goes without saying, but in addition to being UI agnostic, your business logic should also be datastore agnostic. To be truly abstract, it should be as easy to move your backend from RDBMS to LDAP or XML as it is to move the UI from Web to GUI to Console. Ian "Turansky, Mark" <[EMAIL PROTECTED]To: "Struts Users Mailing List" <[EMAIL PROTECTED]> rm.com> cc: Subject: RE: designing simple scheduler 12/08/2003 11:05 AM Please respond to "Struts Users Mailing List" "Online is just the icing." Right! The business logic of the application should be UI agnostic. The logic shouldn't know if it was invoked from a console application, a Swing gui app, or a web (Struts!) application. The business logic is (or should be) the same. -Original Message- From: news [mailto:[EMAIL PROTECTED] Behalf Of Vic Cekvenich Sent: Monday, December 08, 2003 10:29 AM To: [EMAIL PROTECTED] Subject: Re: designing simple scheduler No, no that is not what we are saying. Just call the beans from your UI. In this case your UI is console. Same bean that you allready tested. Struts is the fastest way to develop that I know (15 years of IT for me) So your console app check the JavaMail and saves it or send it from db. Same beans and DB struts uses. So any mail shows up online. Batch/async is bread and butter of DP.

job scheduler with struts
We need to implement a job scheduler (similar to unix cron job). Is there a open source schedule which can be used with struts? Any pointers on implementing servlet based scheduler? Thanks, Mihir

Re: job scheduler with struts
Turbine implements a job scheduler, I don't know if they implemented it themself or integrated it from another package. Perhaps this is also one utility that could go in the proposed code sharing library for Jakarta. -Rob Mihir Parekh wrote: > > We need to implement a job scheduler (similar to unix cron job).

Re: job scheduler with struts
Depending on what you want to do, you could put your code into an action, fix it with a URL like http://localhost/thingy.do and then run a job that calls the page. If you're on UNIX get the Perl module LWP, which installs command line scripts, one called GET which will call a URL for you, so then your script line in cron would be GET http://localhost/thingy.do >> /tmp/thingy.log If you're on NT, although it should work I'm not sure. There is an implementation of "at" for NT in the NT resource kit. Otherwise you might have to look at other options. Just be aware if you do't secure the page, then anyone will be able to call it.

RE: job scheduler with struts
I think Mihir was looking for generic code that would run on any platform and be incorporated into the struts framework. The NT scheduler (at) or Unix cron are both os specific solutions. Second, if wanted to call urls, you don't need perl, just use the URL connection in Java. >>-Original Message- >>From: Jim Richards [mailto:[EMAIL PROTECTED]] >>Sent: Sunday, February 25, 2001 3:44 PM >>To: [EMAIL PROTECTED] >>Subject: Re: job scheduler with struts >> >> >> >>Depending on what you want to do, you could put your code into an >>action, fix it with a URL like >> >> http://localhost/thingy.do >> >>and then run a job that calls the page.

Re: job scheduler with struts
Yes ! I am looking for a generic code which can be packaged as part of servlet/jsp application.

Re: job scheduler with struts
Check out http://www.coolservlets.com/ and look for "maintenace package". I hope this is what you are looking for. Mihir Parekh wrote: > Yes !

Is there a scheduler for calling time based actions
hi, i am looking for a scheduler who can call time based struts-actions... Has anybody an idea? thx Elmar -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>

Fulcrum has a nice job scheduler as well. Fulcrum was developed as part of the Turbine Framework. It is now decoupled and can be used by itself. http://jakarta.apache.org/turbine/fulcrum/index.html -Original Message- From: MARK NICHOLS [mailto:[EMAIL PROTECTED]] Sent: Monday, March 18, 2002 10:54 AM To: [EMAIL PROTECTED] Subject: Re: Is there a scheduler for calling time based actions Go to google.com, type "servlet based scheduler for timed events" in the search box.
