4. The Set Up
5. Making A Jar File
1. First You Need To Set You're PATH & CLASSPATH In your Environment Variables.
Attachment 933
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
Code:
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
Code:
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.
Code:
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:
Code:
@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

set b=0
set t=7

echo.

echo.

if %c%==C goto c

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.

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

4. The Set Up:
This is what you should have so far:
Attachment 934
5. COMPILING:
Double-Click The Compiler
Press "C"
Press Enter
If Done Correctly You Should See
Code:
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:
Attachment 935
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
Code:
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
