Update a servlet automatically

Hello,
I try to make a servlet.
but each time i change my .java file, i need to stop and start again TOMCAT for viewing the change on my servlet.
Does he have a way for each time i change my .java file TOMCAT take the update automatically?
i use TOMCAT 5 with Apache on a Gentoo linux.
thanks for helping me!

If you have defined your context definition outside server.xml (should be in path as below),
<TOMCAT_INSTALL/conf/<enginename>/<hostname>/<your_context_name.xml>An example application called webtest running on localhost and with the default engine name as Catalina would have this path.....
<TOMCAT_INSTALL/conf/catalina/localhost/webtest.xmlall you have to do is add an attribute reloadable = "true" to your context definition in the xml above.
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="D:/ram/technical/webtest" path="/webtest"
reloadable="true" workDir="D:\ram\technical\webtest\work">

</Context>Cheers,
ram.

Re: Running servlets automatically.

this is the Continuation of my previous post Running servlets automatically.
Hi everybody tnx for ur replies.
I will explain my problem in detail here,so that somebody can suggest me an suitable solution.
i need to update one table in DB for every six hours.for that purpose i have written a class with thread.sleep().
This class updates the table and sleeps for six hours and it runs after that delay......this process repeats....until the execution is terminated manually.
in the beginning i specified this class as the startup class of the server, but as this class uses thread.sleep() method , it takes the control for ever..and never let the server to run...
so i make this class to run in an independent window
the execution of the class is triggered by the server when it starts.this will open a DOS window and the execution of the class begins.
but the execution continues even after the server gets terminated..coz..it is running as a separate process not under the server process.
but i need to terminate this updation process after the server gets terminated..
so i decided to use an dedicated servlet for this purpose.,..coz it will b terminated after the server gets terminated.
The servlet should
start automatically when the server starts..
and it has to call the Updation class methods..
and prints the result message ..
it has to call itself after six hours delay..
this delay should not affect other components of the server and its processes.
plz help me
thanx in advance

Personnally a Servlet isn't the correct way to perform this task. I'ld use a ServletContextListener, add the instance to the ServletContext so then it can be accessed from say startScheduler.jsp, endScheduler.jsp & displayStatusOfScheduler.jsp.
Your web.xml would need the following added:<listener>
 <listener-class>package.subpackage.ContextLifeCycleListener</listener-class>
</listener>Create the listener.package package.subpackage;
imports ...
public class ContextLifeCycleListener implements ServletContextListener {
 private ServletContext servletContext = null;
 private ContextLogger contextLogger = new ContextLogger( false );
 public void contextInitialized( ServletContextEvent servletContextEvent ) {
 servletContext = servletContextEvent.getServletContext();
 servletContext.setAttribute( "backgroundScheduler", this );
 public void contextDestroyed( ServletContextEvent servletContextEvent ) {
 terminateScheduler();
 public void startScheduler() {
 // ... Start Scheduler Processing
 public void terminateScheduler() {
 // ... Terminate Scheduler Processing
 public String//boolean status() {
 return ?; // boolean, eg scheduler on or off
 // String, eg "Off", "On", "Running"
}That will create a process which starts when the context does & is informed when the context is restarted or stopped. This then hides it away meaning someone can't access it directly by typing in a url. Only your Servlet/JSP/JSTL can access it via the ServletContext Attribute "backgroundScheduler".

Hi, I'd like to set alarms or reminders on my I phone or I pad so that it can update or sync automatically with each other. I don't know if this is possible or how to do it. I hope you can help..

HI, if I did this, then I believe that I cloud would then hold my info which I don't want. Is that the case? The reason is that I'm an old git, therefore used to not giving out info. Would I be right?
Thank-You so much for taking the time to answer.

Why can I not disable the guest user in the 10.8.2 update? I have never enabled the guest user, but after the update, it was automatically enabled with a "managed" tag. It is not selectable even after entering my admin password to unlock the options.

Why can I not disable the guest user in the 10.8.2 update? I have never enabled the guest user, but after the update, it was automatically enabled with a "managed" tag. It is not selectable even after entering my admin password to unlock the options. I was able to select the account under "parental controls", but again, could not delete it. Why Apple? Why?!!????

SOLVED Ok. I actually was able to disable it. I had to actually log in as the guest user to make it accessible in the preference window. Then I disabled it and logged out. Apologies if this was obvious for some people, but I have had some sort of issue with something every update since Snow Leopard.

IWork apps not updating iCloud files automatically

My iWork apps (pages, keynote, numbers) on my MacBook Pro quit updating iCloud files automatically. Also the apps will not show files created or updated on my iPhone or iPad automatically. If I restart or shut down my MacBook Pro, then the iCloud files are updated at the launch of the iWork app. The iWork apps were updating the iCloud files antomatically until two days ago. I am looking for suggestions on how to get the automatic iCloud file update feature working again.

Yes I am using Mountian Lion. Automatic syncing was working great up to about 2 days ago. Then it just quit. I could turn the mac off and back on and it would sync, but still would not automatically. None of my troubleshooting tricks fixed the issue. Finally I reinstalled Mountian Lion and now the iWorks apps are syncing. I still don't the know the reason for the issue, but a complete start over solved the issue for now. Thanks for your comments.

My iphone 5 clock is not working properly. I've tried to reset it, and update the clock automatically and manually, and the time is still off. My alarms aren't working because of this, and I need my phone to work properly.

Automatic time is a function of your Wireless carrier. Your post indicates that your iPhone (5 or 5c) is running iOS 7.0.6. The current version is 7.1.1. You might try updating your device to the current iOS version.

Update group in automatic credit control

Hi Everybody,
Can anyone explain me the meaning of update group in automatic credit control screen OVA8.
Do we have to set this update or it happens when we start usinng?
Regards,
raghu

Hi,
More info on this ,
Credit update for open order/delivery/billing document value
The credit update controls when the values of open sales orders, deliveries, and billing documents are updated.
Note
The open order value is only updated for schedule lines that are relevant for delivery.
Use
You can specify the following update groups for updating credit-related statistics:
Update group 000012
Sales order
Increases open order value from delivery-relevant schedule lines
Delivery
Reduces open order value from delivery-relevant schedule lines
Increases open delivery value
Billing document
Reduces open delivery value
Increases open billing document value
Financial accounting document
Reduces open billing document value
Increases open items
Update group 000015
Delivery
Increases open delivery value
Increases open billing document value
Financial accounting document
Reduces open billing document value
Increases open items
Update group 000018
Sales order
Increases open delivery value
Billing document
Reduces open delivery value
Increases open billing document value
Financial accounting document
Reduces open billing document value
Increases open items
Note
If a document cannot be processed with the update group you specify, the system determines the next possible update it can carry out. For example, you select Update group 000012 which, at delivery, reduces the open order value and increases the open delivery value. Assume that one item in the order is not relevant for delivery. In this case, the system automatically determines Update group 000018 for this item. Update group 000018 increases the open delivery value for the order item. The system uses the confirmed quantity of delivery-relevant schedule lines to update the order value.
Hope it adds. Pl reward if helpful.
Thanks & Regards

Run servlet automatically when tomcat startup

Dear all
I need help to run servlet automatically when tomcat startup without starting even the application containing the servlet
thanks in advance

lol
i've the same problem with my car,I want it to go ahead but without starting the engine and using all this gasoline...
Seriously... the servlet IS almost your application
when you start the server, the application starts to
check the init() method of the servlet Interface
and the "load-on-startup" parameter of the servlet in the deployment descriptor

Why not create a scheduled task (in Windows) or a daemon in *nix to start/stop the context associated with the servlet?
Do a search in these forms for old posts regarding the starting and stopping of contexts....

Software Update Not Working Automatically

Since I upgraded my OS X from Tiger to Leopard, Software Update could not have been working automatically even if it is set to check updates daily or weekly, and the machine is turned on at the scheduled time with an Internet connection. Well, by clicking on "Check Now," I can manually check to see if any updates are available, though.
Does anyone know how to fix this problem?

Thank you for your response, Ahsan.
But, Software Update should run automatically according to your setting, whether or not any updates are available. If nothing is available, Software Update displays a "Last check" date and time, and says, "No updates are available" or something like that. In fact, when I just manually hit "Check Now" button, Software Update did find "Time Machine and AirPort Updates v1.0" published on 3/19/08 while I had set it in the preference "weekly" almost two weeks before.
Strange, isn't it?
