Re: hello world question !!!

[Gregg Reynolds]

There once was a man named Gustava
Whose Clojure code smelled just like Guava
He tried to use gen-class
Which made it smell stink-ass
So he went back to working in Java

Hardy-har-har.  Containers long for bytecode on disc. You can minimize it,
but you have to have it to bootstrap the Clojure runtime.

I think you can use lein-ring or lein-uberwar to package any ring based clojure 
web app into a War.

But, a War is just a zip file with a known set of files and directory 
structure. So depending on your needs, you could create it yourself too.

Re: mysql and clojure

[Damien Mattei]

thank for your help, i had doubt about namespace but as i focused on sql i 
did  not check it, it is just a week i use clojure, but i'm used many 
Scheme and LisP and Java and there is a lot of issue on stackoverflow or 
stackechange about clojure and mysql that are out of date and are confusing
