Assume your project folder structure as follows :

c:\test\classes\com\test\awt\Example.class

c:\test\classes\manifest.txt

You can issue following command to create a “Example.jar.

jar -cvfm Example.jar manifest.txt com/test/awt/*.class

For Example :

go to folder structure from commmand prompt "cd C:\test\classes"

C:\test\classes>jar -cvfm Example.jar manifest.txt com/test/awt/*.class

To avoid to add sources files  java to your package you should do  cd src  jar cvf mylib jar com      class   Supposed that your project structure was like  myproject      src        com          mycompany            mainClass java           mainClass class

You need to start creating the JAR at the root of the files   So  for instance   jar cvf program jar -C path to classes     That assumes that path to classes contains the com directory   FYI  these days it is relatively uncommon for most people to use the jar command directly  as they will use a build tool such as Ant or Maven to take care of that  and other aspects of the build   It is well worth the effort of allowing one of those tools to take care of all aspects of your build  and it s even easier with a good IDE to help write the build xml  Ant  or pom xml  Maven
