Para no utlizar funciones de javascript y cada vez que se quiera cambiar el color de un tr de una tabla se puede utilizar esto.


$(document).ready(function() {
$(function() {
$('.actionRow').hover(function() {
$(this).css('background-color', '#FFFF99');
},
function() {
$(this).css('background-color', '#FFFFFF');
});
});
});

obviamente agregas jquery a la pagina

Lectura de archivos de una carpeta


import java.io.File;
import java.io.FilenameFilter;

public class FileFilterTest {

public static void main(String[] args) {

FilenameFilter filter=new FilenameFilter(){
public boolean accept(File dir, String fileName) {
return fileName.endsWith("java");
}
};

File f=new File("D:/Programs/Code");
String [] fileList=f.list(filter);
for (int i=0; i < fileList.length; i++){
System.out.println(fileList[i]);
}
}

}


El objetivo de este post es juntar todas las apis, bibliotecas, frameworks, plug ins y herramientas para que las podamos consultar en un futuro, espero que me puedan ayudar para que la lista crezca. GRACIAS !!

Para poder cargar dll's en java se puede tener varios caminos como puede ser

System.loadLibrary("d:\\directoryX\\subDirY\\MyDll.dll")

ó

System.load("d:\\directoryX\\subDirY\\MyDll.dll");

utilizando la clase Runtime

Runtime.getRuntime().load("d:/directoryX/subDirY/MyDll.dll");

especificando a la jvm

java -Djava.library.path=c:/temp JNIJavaHowTo

y la exception que se lanza es java.lang.UnsatisfiedLinkError

para regresarla a la normalidad

gconftool-2 --type=Boolean --set /apps/nautilus/preferences/always_use_location_entry false

la siguiente aplicacion es un ejemplo de SystemTray con java, esta funcionalidad fue incorporada en java SE 6

Este es un ejemplo basado en un codigo de oracle

import java.awt.Image;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener; java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class SystemTrayTest {

    private TrayIcon trayIcon = null;

    public SystemTrayTest() throws Exception {

        if (SystemTray.isSupported()) {

            SystemTray tray = SystemTray.getSystemTray();
            Image image = Toolkit.getDefaultToolkit().getImage("tray.png");

            MouseListener mouseListener = new MouseListener() {

                public void mouseClicked(MouseEvent e) {
                    System.out.println("Tray Icon - Mouse clicked!");
                }

                public void mouseEntered(MouseEvent e) {
                    System.out.println("Tray Icon - Mouse entered!");
                }

                public void mouseExited(MouseEvent e) {
                    System.out.println("Tray Icon - Mouse exited!");
                }

                public void mousePressed(MouseEvent e) {
                    System.out.println("Tray Icon - Mouse pressed!");
                }

                public void mouseReleased(MouseEvent e) {
                    System.out.println("Tray Icon - Mouse released!");
                }
            };

            ActionListener exitListener = new ActionListener() {

                public void actionPerformed(ActionEvent e) {
                    System.out.println("Exiting...");
                    System.exit(0);
                }
            };

            PopupMenu popup = new PopupMenu();
            MenuItem defaultItem = new MenuItem("Exit");
            defaultItem.addActionListener(exitListener);
            popup.add(defaultItem);

            trayIcon = new TrayIcon(image, "Sistema de alarmas ConQuest", popup);

            ActionListener actionListener = new ActionListener() {

                public void actionPerformed(ActionEvent e) {
                    trayIcon.displayMessage("Alarma",
                            "una alarma se a presentado",
                            TrayIcon.MessageType.WARNING);
                }
            };

            trayIcon.setImageAutoSize(true);
            trayIcon.addActionListener(actionListener);
            trayIcon.addMouseListener(mouseListener);

            //    Depending on which Mustang build you have, you may need to uncomment
            //    out the following code to check for an AWTException when you add
            //    an image to the system tray.

            //    try {
            tray.add(trayIcon);
            //    } catch (AWTException e) {
            //        System.err.println("TrayIcon could not be added.");
            //    }

        } else {
            System.err.println("System tray is currently not supported.");
        }
    }


    public void alertWarining(String title, String message) {
        trayIcon.displayMessage(title, message, TrayIcon.MessageType.WARNING);
    }


    public void alertError(String title, String message) {
        trayIcon.displayMessage(title, message, TrayIcon.MessageType.ERROR);
    }

    public void alertInfo(String title, String message) {
        trayIcon.displayMessage(title, message, TrayIcon.MessageType.INFO);
    }

    public void alertNone(String title, String message) {
        trayIcon.displayMessage(title, message, TrayIcon.MessageType.NONE);
    }
} //end class

la clase SystemTrayTest crea una instancia de TrayIcon y verifica si tiene soporte el sistema operativo. implementa los metodos necesarios y crea un menu para mostrar la salida del programa.

la clase SystemTrayTest contiene los metodos alertWarning(), alertError(), alertNone() y alertInfo() para mostrar mensajes en la pantalla


La clase SystemTrayIcon contiene el metodo principal que crea un objeto de SystemTrayTest, utilizando swingWorker

/**
*
* @author skuarch
*/
public class SystemTrayIcon implements Runnable {

    java.awt.TrayIcon trayIcon;
    java.awt.SystemTray tray;

    /**
     * Construct.
     */
    public SystemTrayIcon() {
        super();
    } //end SystemTrayIcon

    /**
     * @param args the command line arguments
     */
    public static void main(String... args) {
        Thread t = new Thread(new SystemTrayIcon());
        t.start();
    } //end main

    @Override
    public void run() {

        try {
            javax.swing.SwingUtilities.invokeLater(new Runnable() {

                @Override
                public void run() {
                    try {
                        SystemTrayTest stt = new SystemTrayTest();
                        stt.alertWarining("Inicio", "este es un mensaje de inicio");
                    } catch (Exception ex) {
                        System.out.println(ex);
                    }
                }
            });
        } catch (Exception e) {
            System.out.println(e);
            throw new UnsupportedOperationException("Not supported yet.");
        }

    } //end run
} //end class


SystemTrayIcon implementa Runnable y dentro del metodo abstracto se crea el siwngWorker.

Los requisistos para poder instalarlo es tener apache instalado en este enlace se mustra como instalarlo obviamente solo instalarias apache instalar mysql, apache y php

paso 1 instalando lo necesario

sudo apt-get install -y subversion libapache2-svn

paso 2 creando el repositorio en /svn
