In this post, we will learn to run a .jar file from a .bat file.
Let’s say, we have a JAR file and want to run it using a batch file. So that, we can double click on it and start our Java application.
NoteThe batch and bat words are used to refer same thing. The only difference is that, batch is the file format that holds some command to do some action and the bat is the extension of the batch file.
First, we need to create a file with extension .bat.
For example, I have a HelloWorld.jar file and want to run it from batch script.
In this case, Let’s create a HelloWorld.bat file. (I would prefer to keep the same name as my jar file for bat.)
Note:If you are creating the bat file using notepad then make sure to select Save as type: All. If you don’t do this, even you give the file name HelloWorld.bat it still saves the file as a text document.
Let’s add content to our batch file:
@ECHO OFF start java -jar HelloWorld.jar
With this code, make sure your .jar and .bat files are in the same location.
If you want to keep your jar file and bat file in different locations then you need to provide the relative location of your jar file.
Now, we can run the batch file by double-clicking on HelloWorld.bat file.
When we double click on the bat file, then it should automatically start a jar file.
Hence, we are able to run our JAR file with the help of a batch (bat) file.
