Want to get data from java file

Question

Hi,
I am creating a program using JBuilder. All is going fine but im having trouble reading data. Well, I want to read data from a java program which is in the same package of my program but when i wrote the command to read it i get a Exception saying:
"java.io.FileNotFoundException: dataControl2.java (The system cannot find the file specified)"
Below is the program i wrote to do this:
The hole point of my program is to get temporary stored data from my conrol program that stores the data and saves it to a file. This program needs to get the user name and password and if the password is enabled or not.
try {
FileInputStream fi = new FileInputStream("dataControl2.java");
ObjectInputStream oi = new ObjectInputStream(fi);
dataControl2 dat = (dataControl2) oi.readObject();
jTextField1.setText("" + dat.userName);
if (dat.usePassword == 1) {
jPasswordField1.setEditable(false);
usePassword = 1;
oi.close();
} catch (Exception e) {
jTextField1.setText("" + e.toString());
I understand that the file cant be found, that wasnt hard to work out, but the thing is that the file does exist so i think i have wrote me program wrong.
If you can see wat i have done wrong or wish to learn more about my query email me at:

Answer 1

well, i did that and this is what my program looks like now:
try {
File aFile = new File("dataControl2.java");
System.out.println("absolute path : " + aFile.getAbsolutePath());
FileInputStream fi = new FileInputStream(aFile);
ObjectInputStream oi = new ObjectInputStream(fi);
dataControl2 dat = (dataControl2) oi.readObject();
jTextField1.setText("" + dat.userName);
if (dat.usePassword == 1) {
jPasswordField1.setEditable(false);
usePassword = 1;
oi.close();
} catch (Exception e) {
jTextField1.setText("" + e.toString());
System.out.println("");
System.out.println("" + e);
Well, now i get a message saying that the file is corrupted.
I have really screwed this up but i really need to get this fixed.
If possible i can zip my java program and send it to you if you ask!
