javaw.exe problem in Task Manager

[sarwar1234]

Hello ....


I have built a Java Program that basically uses a JFrame and Jpanels on top of that....

When I run the main class file... All works fine....

I ran that application several times to check different things... After some time my PC began to slow down too much....

When I checked the "processes" under the Windows Task Manager...
There was a file javaw.exe in the processes of my Task Manager.... And this file/process does not remove as soon as I close the application.... Instaed I have to End the process from the task manager....

Does any one have an idea... why is that process there and how to end this process as soon as I close my application.... ??

Many Thanks for the cooperation....

Best Regards,
Sarwar

Ah... One important thing...

Also a new process javaw.exe is created each time I run the application....

So as many time I run the application... I get more and more javaw.exe processes in the task manager....

Any idea...

Thanks

Can you show us how you exit the application? There should be a bit of code in your JFrame handling class (hint: see EXIT_ON_CLOSE).

Hello....


This is my main class with main method.... that executes the JFrame....

import javax.swing.JFrame;
import javax.swing.UIManager;

import com.sun.java.swing.plaf.windows.WindowsLookAndFeel;


public class WindSpeedAnalysis {
	
	/**
	* @param args
	*/
	public static void main(String[] args) {
	// Auto-generated method stub

	try {
	UIManager.setLookAndFeel(new WindowsLookAndFeel());
	}catch (Exception e) {
	}

	JFrame f = new JFrame("Wind Speed Analysis");
	f.setSize(800, 600);

	MainPanel mainPanel = new MainPanel();

	f.add(mainPanel);

	f.setVisible(true);


	}

}

Do I need to do some thing with the JFrame to end the process javaw.exe ??

Many Thanks......

Read all about it in the API documentation of the setDefaultCloseOperation() method in the JFrame class.

	f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
