How do I run a .jar executable java file from outside NetBeans IDE?

Question

How do I run a .jar executable java file from outside NetBeans IDE? (Windows Vista). My project has a .jar file created by Netbeans. We'd like to run it. Either: how do we run the file or how do we create a 'proper' executable file in NetBeans 6.1?

One of the best technique to run the jar file or jar jar file

Create the jar file by jar command choose your jar filename Java_Jar_File.jar
Run the jar file us the command like java -jar Java_Jar_File.jar

You can do it from the command prompt if java isn't in your path by finding the full path to your java install, something like:

C:\java\java.exe -jar C:\jar_you_want_to_run.jar

or if java is in your path:

java.exe -jar jar_you_want_to_run.jar

This will run the jar produced by netbeans.

First, make sure you set the Main Class in your NetBeans project properties dialog.
Then, you can either

Double-click the jar file (This should work on any machine with an installed JRE)

or

Make sure that java.exe is in the path (or replace java below with the fullpath and file name of the executable), put the following in a batch file:
java -jar filename.jar
Then you can double-click the batch file instead of the jar (useful if you have people unaccustomed to using naked jar files)

OR

You can go down the path described here How can I convert my Java program to an .exe file? to build a .exe for windows.

To run a java jar file its file association should be properly configured. There is a free tool called jarfix to fix all jar file association problems. Run this file to fix all jar issues.

If you have problems with running your jar, make sure you are trying to run your current version to get newest version in Netbeans: GoTo Run Menu --> Clean and build

In the project properties dialog in NetBeans you need to set the Main Class - otherwise the generated .jar will not be executable. Then, as already indicated, either double clicking on the .jar or the command java -jar will start the program.
