How To Create Batch File For Java Project

4 Answers 4

Because you are working in eclipse, this makes things easier. First, export the whole program as a executable jar. You can do this by going to Files>Export and then in the pop up go to Java>Runnable Jar. Then follow the steps required to make it. Next you make a .bat file and write the following code.

start javaw -jar NameOfJar.jar

Make sure that you put the file in the same directory as your jar. Now you should be able and click on the .bat and execute the program!

created .bat file.. when i click it to run my jar, a cmd window opens and gets closed automatically

yeah, a batch file is really just a command prompt command, so the window will always open, no matter what you do. If you don't want the window then you will need to use a executable wrapper

1.Open Notepad & write

                @echo off  javac YOUR_JAVA_FILENAME.java  java YOUR_JAVA_FILENAME

2.Save-As executeJavaProgram.bat

Make sure that YOUR_JAVA_FILENAME.java resides with your batch file and java path is set in environment variable.

3 . Double click on batch file.

Create jar file using eclipse i.e right click on your project select export jar file then provide file name to store your jar file. In this file eclipse will keep all .class file only and in META-INF folder main class definition if your are creating executable jar file.
