我是Java的新手也是我在这个网站上的新手,所以如果错误很明显我很抱歉,但我收到了一个错误,我不知道这意味着什么,我已经尝试了一切来修复它.

我目前正在编写一个基本的应用程序库,带有一些swing接口,但问题是当试图创建一个书形式的窗口时,有相关的代码.

这是主要窗口.

 public class VentanaPrincipal extends javax.swing.JFrame {

   public VentanaPrincipal() {
     initComponents();
     this.setLocationRelativeTo(null);
}

private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    EscribirBinario escritor = new EscribirBinario();
    //   Collections.sort(ListaClientes.clientes);

    if (escritor.abrir(Main.archivo1)) {
        for (int indice = 0; indice < ListaClientes.clientes.size(); indice++) {
            escritor.escribir(ListaClientes.clientes.get(indice));
        }
        escritor.cerrar();
    }
    System.exit(0);
}                                        

private void bt_clienteActionPerformed(java.awt.event.ActionEvent evt) {                                           

    MantenimientoCliente clientes = new MantenimientoCliente(this, true);
    clientes.setVisible(true);
}                                          

private void bt_libroActionPerformed(java.awt.event.ActionEvent evt) {                                         

    MantenimientoLibro book = new MantenimientoLibro(this, true);
    book.setVisible(true);
}                                                    

   }

有书的形式的代码.

 public class MantenimientoLibro extends javax.swing.JDialog {

  public MantenimientoLibro() {
   }

public MantenimientoLibro(java.awt.Frame parent, boolean modal) {
    super(parent, modal);
    initComponents();

    this.setLocationRelativeTo(null);
}


public MantenimientoLibro(java.awt.Dialog parent, boolean modal) {
    super(parent, modal);
    initComponents();
    this.setLocationRelativeTo(null);

}           

private void bt_salirActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    this.dispose();
}                                        

private void bt_insertarActionPerformed(java.awt.event.ActionEvent evt) {                                            
    // TODO add your handling code here:
    FormularioLibro formulario = new FormularioLibro(this, true);

    formulario.setVisible(true);
    this.dispose();

}                                                    

}

这是我得到的错误：

解决方法:

看看bug report here.它有你的问题的解决方案：

From the nbusers mailing list I got the following hint:

"workaround it by deselecting 'Compile On Save' in the project options".  

马克在评论中指出的答案也是一致的.这是同样的链接：
