another jar question

ThatJive · Oct 4, 2006

Hi,

I have a really simple program that I put into a jar file. I followed the tutorials and managed to get
it to work, but only while the jar is in the same folder as all the files that went into it. When I move
the jar to my desktop and try to execute; it wont open. I gotta be doing something wrong here,
any help, tips or abuse is greatly appreciated. Oh by the way, I'm using a Mac Book Pro.

Thanks

Here is the command I used to build the jar:

Code:

billMBP:~/desktop/lab6_Find1 bill$ jar cvfm Find1.jar myManifest.txt Find1.class invoice.dat Q_icon.jpg  W_icon.jpg
added manifest
adding: Find1.class(in = 2633) (out= 1612)(deflated 38%)
adding: invoice.dat(in = 35) (out= 35)(deflated 0%)
adding: Q_icon.jpg(in = 17902) (out= 17020)(deflated 4%)
adding: W_icon.jpg(in = 6758) (out= 6749)(deflated 0%)

Here is what is in the jar

Code:

billMBP:~/desktop/lab6_Find1 bill$ jar xvf Find1.jar
 created: META-INF/ 
 inflated: META-INF/MANIFEST.MF
 inflated: Find1.class
 inflated: invoice.dat
 inflated: Q_icon.jpg
 inflated: W_icon.jpg

Here is my manifest:

Code:

Manifest-Version: 1.0
Main-Class: Find1
Created-By: 1.5 (Sun Microsystems Inc.)

Here is my src:

Code:

import java.io.*;
import java.util.*;
import java.text.DecimalFormat;
import javax.swing.*;
 
public class Find1 {
 
	public static void main(String[] args) throws FileNotFoundException {
     
	  	DecimalFormat dF = new DecimalFormat("0.00");
		Scanner fr = new Scanner(new FileReader("invoice.dat"));
		double itemPrice = 0;
		String itemFromStock = null;
		String usrIn = null;
		boolean found = false;
		
    
		Icon Q = new ImageIcon("Q_icon.jpg");
		JLabel Qjl = new JLabel("Please enter the name of the item you "
				+ "want information about...", Q, JLabel.CENTER);	
		usrIn = JOptionPane.showInputDialog(null, Qjl, "SUPER INVENTORY "
				+ "SEARCH FACILITATOR ©2006", JOptionPane.PLAIN_MESSAGE);
		
    
		while (!found && fr.hasNext()) {
	 			itemFromStock = fr.nextLine();
    
			if (usrIn.equalsIgnoreCase(itemFromStock)) {
     
				found = true;
				itemPrice = fr.nextDouble();
	  				JOptionPane.showMessageDialog(null, "The " 
								+ itemFromStock
								+ " is available for:  $"
								+ dF.format(itemPrice), "Your Inquiry Results",
								JOptionPane.INFORMATION_MESSAGE);
			}
 
		}   
		
		if (!found) {
			Icon W = new ImageIcon("W_icon.jpg");
			JLabel Wjl = new JLabel(
					"<html>\"<strong>Sorry !!</strong> but, we don't carry  "
							+ "<strong>"
							+ usrIn
							+ "s</strong> anymore. We had a <p>bunch of 'um a "
							+ "while back and they just sat on the shelves</p> "
							+ "till the mice got to 'um and well... I don't " 
							+ "have to tell <em><strong>you</strong></em>"
							+ " how much of a hassle.... blah blah blah..."
							+ "blah..\"</html>", W, JLabel.CENTER);
			JOptionPane.showMessageDialog(null, Wjl, "Sorry for Your Trouble",
					JOptionPane.ERROR_MESSAGE);
		}
      
		fr.close();
		System.exit(0);
	}
 
}
