Thread: Build Java App Exception

Good guys, I'm new to this community and I hope to be able to communicate nicely, well, I come here to present you my problem is that my application is finished and I want to build it, but here there is a problem that does not allow me:
An input/output error occurred.:
Consult the following stack trace for details.

I do not understand why this is, if you could help me.

Have you looked up the API doc for the MalformedInputException class to see why it is thrown?

A marked exception is thrown when an input byte sequence is not legal for a given character set, or an input character sequence is not a legal sixteen-bit Unicode sequence, that's what I don't understand where it is giving this.
What program are you executing that gives that error message?

What program am I basically using java, NetBeans, and the jar for the database connection that and nothing else? On the other hand, in other applications that I have developed when building if it works correctly.

nothing does execute the following problem appears

"error: cannot find symbol
FormLogin login= new FormLogin(frame);
^
symbol: class FormLogin
location: class Initial "
---------------------------
this my code :
package com. app.capa1_presentacionn;

import javax.swing.JFrame;

/**
*
* @author josel
*/
public class Initial {
public static void main(String[] args) {
JFrame frame = new JFrame();
FormLogin login= new FormLogin(frame);
login.setVisible(true);
}
}

"" but when I run the application from NETBEANS running that file if it works correctly ""

Well, thank you very much for the help, at last I tried to solve it, I will tell you in what way, basically, I had to test my application in small parts to better understand what had been developed, and well, basically, it was next to my classes or jframes had called them FormAdd and well that was the only problem how to name them I could not call them with the letter "ñ" for that reason I sent this exception, I hope it does not happen as my problem to others, during all my years of java I had never noticed or they would have mentioned me in a single letter it hurt you all , I tried hard enough to understand the problem and try to fix it
well thanks my friend ...
