Is it possible to complie Java 1.5 source Web Applications to 1.4?

Question

I tried compiling my webapplication with javac – source 1.5 – target 1.4 I end up with the error: javac: source release 1.5 requires target release 1.5

Since I’m using generics and other features; when I try compiling with –source 1.4 I end up with the errors:

(use -source 5 or higher to enable generics)
(use -source 5 or higher to enable for-each loops)
(use -source 5 or higher to enable annotations)

I need to deploy to a box with Java 1.4 installed; of which I have no control of, so upgrades are out of the question.

Suggestions?
