[Guest]

JAR is ZIP?

Can I compress all of my classes & files into a zip and rename it to JAR and
then run it?

Hello Alex,

No.

I refute that, that's bollocks. The JAR file format is the same as the ZIP file format,
with the 'added value' that you can add a META-INF directory to store
metadata. If you just zip everything you can still use it as a jar.

Bhun.

Of course you're quite right.

you use the jar utility, which also creates a manifest entry. Winzip
won't. Winzip despite repeated requests still refuses to acknowledge
jar files as archives. It will treat them as such though if you
search with the *.* option.

*If* you get the manifest right.

It's not as tricky as it used to be, but is a bit of a problem.


So, with the manifest info, that original "No" is technically correct.
