How to create a JAR file in Command Prompt:
· Start Command Prompt.
Navigate to the folder that holds your class files;
· Set path to include JDK’s bin. For example;
C:\mywork> set path=c:\Program Files (x86)\Java\ldk1.8.0_31\bin
· Compile your class(es);
C:\mywork> javac HelloWorld.java
· Create a Manifest file and your Jar file;
C:\mywork> echo main-Class: Hello >manfest.txt
C:\mywork> jar cvfm Hello.jar manifest.txt HelloWorld.class
C:\mywork> jar cvfe Hello.jar Hello HelloWorld.class
This will create your manifest and jar file in the location where your java program is.
· Test your jar directly by typing the following command on your command prompt or simply double click the Hello.jar file from where it is saved.
C:\mywork> java –jar Hello.jar
This will run your java program using JAR file.
