so your provider has an instance method "echo" ...

.. and here you are calling echo in a class context that will execute
as soon as the corresponding file is loaded. So depending on your actual
goal you should either only call echo in an instance method
Puppet::Type.type(:jboss7_deployment).provide(:jboss7, :parent =>
Puppet::Provider::Jboss7) do
def create
echo "I was created"
end
end
or, if you want to call the `echo` method at class level (e.g.
self.prefetch), define your method as a class method in your parent provider
class Puppet::Provider::Jboss7 < Puppet::Provider
def self.echo(arg)
info arg
end
end
Does this make sense?
