Hi Jakob,
Many thanks for your prompt reply. I really appreciate it.
I got your point. It is clear that I'm misusing the '#{resource['...']}'
mechanism.
Apart from your proposed solution, how I can instruct MyFaces to behave as
described in the JEE 6 Tutorial: 'The JavaServer Faces runtime will look for
the resources in the preceding listed locations, in that order (Web Context
then Classpath)'?
You might telling your self: what a lazy guy I'm dealing with. Please,
forgive me please, it is not my intention.
I was developing ZK application (v3.6) where I have developed a mechanism to
load resources from where I need. When I read this part of the Tutorial, I
said to my self: some code is there to avoid with JSF.
Many thanks for your valuable help.
