How to run java executable .jar file from outside of NetBeans IDE?

Question

How to run java executable .jar file from outside of NetBeans IDE? (Windows Vista). My project has a .jar file created by Netbeans. We would like to launch it. Either: how do we run the file or how do we create the “right” executable in NetBeans 6.1?

Answer 1

Running a jar is as easy as

java -jar filename.jar 

Answer 2

as Lapley said, java -jar your.jar

EXECUTABLE file: see this answer topic How do I convert my Java program to a .exe file?

Answer 3

One of the best ways to run a jar or jar jar file

• Create a jar file with the jar command, select your jar file name Java_Jar_File.jar
• Run the jar file with the command java -jar Java_Jar_File.jar

Answer 4

You can do this from the command line if java is not in your path by finding the full path to your java installation, for example:

 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 launch the jar produced by netbeans.

Answer 5

First, make sure you set the Main class in the NetBeans project properties dialog box.
Then you can

• Double-click the jar file (this should work on any computer with a JRE installed)

or

• Make sure java.exe is in the path (or replace java below with the full path and the name of the executable file), put the following in the batch file:
  java -jar filename.jar
  Then you can double-click the batch file instead of jar (useful if you have people who are not used to using bare jar files).

OR

• You can follow the path described here How to convert my Java program to a .exe file? to create .exe for Windows.

Answer 6

Make a bat file with

 java -jar filepath.jar 

Answer 7

from the command line you can run this command: java -jar your_jar.jar .

Answer 8

To run the java jar file, its file association must be configured correctly. There is a free jarfix tool to fix all problems with combining jar files. Run this file to fix all problems with the banks.

Answer 9

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

Answer 10

If you have problems launching your jar, make sure you are trying to run your current version to get the new version in Netbeans: GoTo Run Menu → Clean and build
