5. Making A Jar File








1. First You Need To Set You're PATH & CLASSPATH In your Environment Variables.

Environment Variables.jpg

Notice: You Version Of Java jdk Might Not Be The Same, So Here's How To Find It:

Start -> My Computer -> Local Disk -> Program Files -> Java

You Should See A Folder Like jdk#.#.#_## Or Something In That Nature
This is you version of jdk that needed to be in the PATH & CLASSPATH In your Environment Variables

Example(s):

User Variables For [user]
PATH C:\Program Files\Java\jdk#.#.#_##\bin

System Variables
CLASSPATH C:\Program Files\Java\jdk#.#.#_##\bin



Once you sent that your ready to go.










2. Making Code:

NOTICE: MAKE A NEW FOLDER ON YOUR DESKTOP TO CONTAIN EVERYTHING
NOTICE: MY FOLDERS NAME IS "ExampleJar"

This Is For A Jar Using 2 Classes:

ExampleClass.java

import javax.swing.JFrame;
 
public class ExampleClass{
	public static void main(String[] args){
 
		ExampleClass2 JFrameclass = new ExampleClass2();
		JFrameclass.setSize(200,50);
		JFrameclass.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JFrameclass.setVisible(true);
	}
}

ExampleClass2.java

import javax.swing.JFrame;
import javax.swing.JLabel;
 
public class ExampleClass2 extends JFrame{
 
	private JLabel ExampleLabel;
		public ExampleClass2(){
 
			super("Example");
 
			ExampleLabel = new JLabel("Example",10);
			add(ExampleLabel);
 
	}
 
}

Save This As .Java Files Using Notepad


MAIN-INF

So now you need to tell your jar file which is the main class, This is called MANIFEST.
For this tutorial The main class ExampleClass.

Main-Class: ExampleClass

Save this a manifest.txt
NOTICE: THIS IS SUPER IMPORTANT:
AFTER TYPING "Main-Class: ExampleClass" PRESS ENTER OR YOU WILL GET A ERROR!












3. Compiling Your Code

Short & Sweet:

Simple Batch Compiler: Type:

@echo off
if exist "C:\Program Files (x86)\" set programfiles=C:\Program Files (x86)
set pro=%programfiles%\Java\jdk1.7.0_02
set pro2=%programfiles%\Java\jdk1.7.0_02
set jac=\bin\javac.exe
set jav=\bin\java.exe
:co1
set b=0
set t=7
goto co2
:co2
color %b%%t%
:menu
cls
title The Perfect Compiler version 2.0
echo Please choose an option below to do that function.
echo.
echo c - Compile your server.
echo.
echo.
set /p c=Option:
if %c%==c goto c
if %c%==C goto c
if %c%==* goto er
goto er
:color
cls
echo Would you like to change the backround color, change
echo the text color, or reset it to default?
echo.
echo back - Change the backround color.
echo text - Change the text color.
echo def - Change all colors back to default.
echo.
echo.

Save As Compiler.bat

NOTICE: THIS COMPILER DOES NOT BELONG TO ME!
NOTICE: ADD THIS COMPILER TO ExampleJar/ OR THE NAME OF YOUR FOLDER!

Owner Of Compiler: Moparscape








4. The Set Up:

This is what you should have so far:
WhatYouShouldHave.PNG


5. COMPILING:

Double-Click The Compiler
Press "C"
Press Enter

If Done Correctly You Should See

Files Compiled Successfully!
Press any key to continue . . .

Also ExampleClass.class & ExampleClass2.class
Also A Compile Logs: You Can Delete That, That Is Not Needed (its in the compiler)

This Is What You Should Have Now:
WhatYouShouldHaveNow.PNG






5. Making A Jar File:

Notice: Spelling Is Absolutely Importing, Make Sure Everything Is Correct Before Proceeding.

First:

Open ExampleJar/Your Folder on your desktop
Right click ExampleClass.java
Open Properties
You Will See Location: This Is Very Important. (LEAVE PROPERTIES OPEN)


Second:

Start-> Run-> CMD

We Need To Change Are Directory To Are Local Disk
So In This Case My Local Disk Is C:

So Type: cd C:\
You should See C:\

Now Remember The Location From Earlier?

Type cd "*Location Form Earlier*"



Example:

I Typed Whats In Bold

C:\>cd "Documents and Settings\Owner\Desktop\ExampleJar

Now The New Directory Is:
C:\Documents and Settings\Owner\Desktop\ExampleJar>



Making The Jar File:

Follow Closely (MOST IMPORTANT PART)

Now In CMD Where It Says: C:\Documents and Settings\Owner\Desktop\ExampleJar>

Type:

C:\Documents and Settings\Owner\Desktop\ExampleJar>jar cfmv ExampleJar.jar MANIFEST.txt ExampleClass.class ExampleClass2.class

You Should Then See:

added manifest
adding: ExampleClass.class(in = 438) (out= 319)(deflated 27%)
adding: ExampleClass2.class(in = 453) (out= 300)(deflated 33%)

C:\Documents and Settings\Owner\Desktop\ExampleJar>

NOTICE: IF YOU SEE

java.io.FileNotFoundException: MAINFEST.txt (The system cannot find the file spe
cified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:138)
        at java.io.FileInputStream.<init>(FileInputStream.java:97)
        at sun.tools.jar.Main.run(Main.java:171)
        at sun.tools.jar.Main.main(Main.java:1177)

THE FILES IN NOT THERE YOU YOU HAD MADE A SPELLING ERROR


Now there should be a jar file in ExampleJar On your desktop.

You Have Created Your Very Own Executable Jar File
