Run jar file from unix command prompt (ERROR)

Question

I have a java project that has 10 .java files. A1.java, A2.java......A9.java and Main.java. The project contains a package grand.big.medium.small and all the .java files are inside this package.

I have compiled and created an executable jar file for the project using:

javac grand/big/medium/small/*.java

to run the project I used the command

java -cp . grand/big/medium/small/Main

to create the jar I used the command

jar -cvmf manifest.txt MyJAR.jar *.class

I want to run the jar file from command prompt and I am using the commad

java -cp . -jar grand/big/medium/small/MyJAR.jar

and I getting an error: Error: Could not find or load main class Main

please can anyone tell me why I am getting this error?

Answer 1

Run as:

java -cp . -jar grand/big/medium/small/MyJAR.jar grand.big.medium.small.Main

Assuming you have grand as a directory within current directory and directory hierarchy follows.
