Option '-jar' - Specifying Executable JAR Files
This section provides a tutorial example on how to use the '-jar' option for the 'java' tool to specify an executable JAR file.
In order to use the "-jar" option, we need to create a JAR file with a "Main-Class" attribute in the manifest file.
Here is what I did to create a JAR file, and launch it with the "-jar" option.
First I created a manifest file, hello.fs:
Then I created an executable JAR file, hello.jar, with Hello.class and hello.fs:
C:\herong>javac Hello.java C:\herong>jar -cvmf hello.fs hello.jar Hello.class added manifest adding: Hello.class(in = 416) (out= 285)(deflated 31%)
Finally, I launched the Hello.class program included in the executable JAR file:
C:\herong>java -jar hello.jar Hello world!
