关闭码头网络浏览器时如何终止javaw.exe

Question

我有一个名为 VcctlWrapper.jar 的 javaw 应用程序，它启动嵌入式码头会话、打开浏览器窗口并允许用户将数据输入到 derby 数据库等。该应用程序当前正在使用以下命令启动：

start javaw -classpath "lib/derby.jar:lib/derbytools.jar" -jar "VcctlWrapper.jar"

目前，当用户完成应用程序后，终止 javaw.exe 应用程序的唯一方法似乎是打开任务管理器并手动结束相关进程。我想找到一种方法让 javaw.exe 在用户关闭 Web 浏览器时自动终止。这可能吗？

构成 VcctlWrapper 的源代码非常短，因此我将其全部包含在此处：

package vcctl;

import java.awt.*;
import java.net.*;
import java.nio.file.Path;   
import java.nio.file.Paths;
import java.io.IOException;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.handler.*;
import org.eclipse.jetty.webapp.*;


public class webServiceRunner extends javax.swing.JFrame {

    private URI uri;
    private Desktop desktop;
    private Desktop.Action action = Desktop.Action.OPEN;

    /** Creates new form webServiceRunner */
    public webServiceRunner() {
        // initComponents();

        try {
            startJettyServer();
        } catch (Exception ex) {

        }

        try {
            if (Desktop.isDesktopSupported()) {
                desktop = Desktop.getDesktop();
                try {
                   uri = new URI( "http://localhost:8080/vcctl" );
                } catch (URISyntaxException urisex) {
                }
                desktop.browse( uri );
            }

        } catch (IOException ioex) {
        }

    }

SessionListener 怎么样，当它检测到会话被破坏时，它会退出进程 (http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpSessionListener.html#sessionDestroyed(javax.servlet.http.HttpSessionEvent))

我知道这不会立即发生，只要浏览器关闭后会话持续，它就会持续，但这是我能想到的最好的了
