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?

Answer 1

EXECUTABLE file : see this thread for answers How can I convert my Java program to an .exe file?

Answer 3

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

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

Answer 4

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.

Answer 5

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.

Answer 6

Make a BAT file with

java -jar filepath.jar

Answer 7

from a command prompt you can run this command: java -jar your_jar.jar.

Answer 8

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.

Answer 9

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.
