JFrame java.io.FilePermission

I have a program that only uses JFrame, not JApplet. This is the first time I have had it throw a security exception with FileInputStream and FileOutputStream. Here is the piece of code that is throwing the exception:

Code :

---

 
public static Vector<MyEvent> grabEventVector()
    {
        Vector<MyEvent> v = new Vector();
 
	try{
            FileInputStream f = new FileInputStream("Data.txt");
            ObjectInputStream s = new ObjectInputStream(f);
 
            v=(Vector<MyEvent>) s.readObject();
            s.close();
 
	}catch(Exception e)
	{
            error.setText(e.getMessage());
 
	}
 
        return v;
   }

I understand that this is probably not enough of my code to really help. So here is some context:

Code :

---

package todoitbetterapp;
 
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.Vector;
import javax.swing.JLabel;
 
 
 
public class GlobalClasses 
{
 
    public static JLabel error;
 
    public void GlobalClasses()
    {
        error = new JLabel(" ");
 
    }
 
    //Global Methods
    public static void writeEventVector(Vector<MyEvent> v)//Writes Vector<MyEvent> to file
    {
		try{
			 FileOutputStream f = new FileOutputStream ("Data.txt");
 			 ObjectOutputStream s = new ObjectOutputStream(f);
 
			 s.writeObject(v);
			 s.flush();
			 s.close();
 
		}catch(Exception ex)
		{
			//error.setText(ex.getMessage());
		}
    }
 
 
 
 
    public static Vector<MyEvent> grabEventVector()
    {
        Vector<MyEvent> v = new Vector();
 
	try{
            FileInputStream f = new FileInputStream("Data.txt");
            ObjectInputStream s = new ObjectInputStream(f);
 
            v=(Vector<MyEvent>) s.readObject();
            s.close();
 
	}catch(Exception e)
	{
            error.setText(e.getMessage());
 
	}
 
        return v;
    }
 
 
 
}

These methods get called often by several other classes, so I put them all into one convenient class. Please let me know if I need to put more code down.

Please post the full text of the error message.
Change the code by adding a call to printStackTrace in the catch block so you get the FULL error message

I figured it out. It was a silly mistake. I working in NetBeans IDE and my configuration was in WebStart... When I changed it to <default config> I no longer got the errors. Since it is more a personal app, I really don't care. Thanks though.
