Creating Jar file from the command line

The Java Development Kit includes a command-line program named jar that can be used to create jar files. If all your classes are in the default package (like most of the examples in this book), then the jar command is easy to use. To create a non-executable jar file on the command line, change to the directory that contains the class files that you want to include in the jar. Then give the command jar cf JarFileName.jar *.class jar file with class that has a main method: Main-Class: ClassName where ClassName should be replaced by the name of the class that contains the main() routine. jar cmf ManifestFileName JarFileName.jar *.class to create the jar file. (The jar command is capable of performing a variety of different operations. The first parameter to the command, such as "cf" or "cmf", tells it which operation to perform.) By the way, if you have successfully created an executable jar file, you can run it on the command line using the command "java -jar". For example: java -jar JarFileName.jar
