Pessoal bom dia.
Eu tenho um projeto que é somente para autentica o acesso do usuário ao banco (é um login).
Eu utilizo este projeto em diversos outros projetos . contudo ele dá um erro javax.imageio.IIOException:

[code]public class FrmLogin extends javax.swing.JDialog implements ActionListener, KeyListener {

/** Creates new form asdasfdfa */
private FrmLogin() {
    this.setUndecorated(true);

    this.setResizable(false);

    jTextField1.addActionListener(this);
    jTextField2.addActionListener(this);

    this.jComboBox1.addItem(ConnectionFactory.getDataBase().getNome());

    this.addKeyListener(this);
    System.out.print(this.jImagePanel1.getComponents().length);
    for (Component comp : this.jImagePanel1.getComponents()) {
        comp.addKeyListener(this);
    }

    this.setLocationRelativeTo(this);
    this.setVisible(true);

neste caso como faço para carregar a imagem que esta em outro projeto?

De tanto ter esse erro criei uma classe para resolver o problema.


#####
Class ImagemLoad
#####
package utils;

import java.awt.image.BufferedImage;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;

public class ImagemLoad {

    public BufferedImage imageLoader(String imgString) {

        ClassLoader ccl = Thread.currentThread().getContextClassLoader();

        BufferedImage imagem = null;
        try {
            URL imgUrl = ccl.getResource(imgString);
            if (imgUrl == null) {
                throw new IllegalArgumentException("imgString='" + imgString + "' is not a valid image!");
            }

            imagem = ImageIO.read(imgUrl);
        } catch (IOException ex) {
            System.out.println(ex.getMessage());
        }

        return imagem;
    }
}

#####
Class ToImageIcon
#####
package utils;

import java.awt.image.BufferedImage;
import javax.swing.ImageIcon;

public class ToImageIcon {

    public ImageIcon toImageIcon(BufferedImage img) {
        ImageIcon icon = new ImageIcon(img.getScaledInstance(img.getWidth(), img.getHeight(), 10000));
        return icon;
    }
}

Agora, explicando o que o corre.

O uso de thread se da devido a rotina não saber qual thread estará rodando este código
então se o classloader que carregou esta classe for diferente do classloader que está rodando a thread
ele não vai encontrar a imagem mesmo ela estando lá

para usar a classe é simples

javax.swing.ImageIcon myImage = new ToImageIcon().toImageIcon(new ImagemLoad().imageLoader("imagem/imagem.png"));
