[chef] Re: Re: Noob Alert: languages attribute?

[Seth Chisamore < >]

You may want to take a look at the "tomcat" cookbook vs "tomcat6".  It's install process is less complicated as it relies on the underlying OS package system to do the install vs installing from source.  It also as an explicit "depends" on the java cookbook which ensures a JVM is installed.

I somewhat fixed the attribute issue with OHAI-227 [0], but I actually think we need a simple attribute like ["languages"]["java"]["flavor"] which just contains something like sun, openjdk, harmony etc.  Until this is officially fixed in the Ohai gem, you can write your own Ohai plugin (that creates the proper java/runtime java/hotstop attributes) and distribute it to your nodes using the Ohai cookbook [1][2].

I've encountered this and other java identification bugs before. I
worked around them by writing my own function for java flavor
identification, but i'm not a java man and I doubt my function will work
with the multitude of java versions out there.

This is a bug in Ohai and should be fixed. I'll check if there are any
open tickets, but we need someone who can test against as many JVMs as
possible.
