Hello All,
In our application we are loading config files(*.txt files) at Init method, and it
will be stored in ServletContext. Thing is any time config file(s) values may change,
so a demon process should update the latest config file(s) into ServletContext, till
now we are restarting the servlet runner to update the latest
files.
Actually, i want to update the files without restarting the ServletRunner. For pilot
test i wrote a Java application in that i used "Timer" class, which use check the
files status continuously for the given time DELAY. This works very fine as a just
Java application..
import java.io.*;
import javax.swing.*;
public class Test
{
public static int chk = 0;
public static void main( String [] args)
{
DummyAction lDummyAction = new DummyAction();
Timer startTimer = new Timer(10000, lDummyAction);
startTimer.setDelay(10000);
startTimer.setRepeats(true);
startTimer.start();
while(true); // keep live the main Thread
}
} // end of test class
class DummyAction implements java.awt.event.ActionListener
{
public DummyAction(String dirName)
{ System.out.println("Object Created : "); }
public synchronized void actionPerformed(java.awt.event.ActionEvent event)
{
// Chk file current time and the registered previous time and upload the changed
files
// ACTUAL IMPLEMENTATION.....
}
}// end of DummyAction (inner class)
} // end of Test class (outer calss)
Question ???
-------------
but when i implement this in my Servlet it's not at coming after this
"startTimer.start();" statement.
1. I added the following code, in Init method, class DummyAction is the Inner class of
my Servlet
2. How can write this as a demon process.
Timer startTimer = new Timer(10000, lDummyAction);
startTimer.setDelay(10000);
startTimer.setRepeats(true);
startTimer.start();
Can some one suggest me the suitable place to implement this logic.
Regards
G S Sundaram
