MANIFEST needed in submission.jar?

[Andy Jung]

Hi all,

when packaging all the stuff in the submission.jar a default MANIFEST is created.
Is this really needed for submission.jar or can it also be deleted?

Kind regards,
Andy

I didn't delete it from my submission jar

One of my requirements was to be able to call the application with 'java -jar runme.jar [mode]'. I believe that I must have the manifest with the Main-Class set correctly. Maybe you have the same requirement?

... yes, I have the same requirement. For runme.jar a MANIFEST is needed, since it is an executable, but this is apparently not true for submission.jar, which contains the runme.jar and all other documents just for submission purposes.

Hi Raf,

You must create 2 jars: a runme.jar and a submission jar. The 1st one will have to be execute with the -jar option, so that one will need a MANIFEST indicating the main class. Not providing it, will lead to automatic failure, because your runme.jar becomes quiet useless. For the submission jar (containing all the files needed for your submission) a MANIFEST is not needed, so you can delete it.

Kind regards,
Roel

Ahh true. I haven't got to that part, yet. Sorry for the confusion.

... no problem at all

I just kept the MANIFEST.MF file in the runme.jar file and deleted the MANIFEST.MF file from the submission.jar file (it wasn't this name back then, but still ).
