The exec resource has a create attribute :

- **creates**
     A file to look for before running the command. The command will
     only run if the file **doesn''t exist.**

create => "target file jdk download"

Or us the -c option with wget.

Or make a package of the java, and install it via the package resource : 
(my preferred way)

here is an example for RPM packages : (we need multiple java versions to 
co-exists on the same system ..)

We just download the RPMs and place them in a custom repository. That way we
don''t mess with the exec stuff or anything. Is there any reason you
don''t use the RPMs
