I created a jar file of a package.
And in the manifest file ,wrote the code

Main-Class:com.MyClass

There is no problem in creating the jar file using the following
command-

c:\>jar -cmf abc.mf MyJar.jar com

but when I tried to execute the program using

c:\>java -jar MyJar.jar
It thrown an error
Failed to load main class from manifest file.

Please provide solution to this problem.
Thanks in advance.

U have to create the jar file by giving the Main class in the
argument
You can create a file Manifest.txt having the following line

Main-Class: com.MyClass


then create the jar using the following command


jar -cmf Myjar.jar Manifest.txt com.MyClass

Then execute the command to run the jar file

java -jar Myjar.jar
