Problem with JOGL Alpha on Canvas

[Goodspeed]

I've created a new Layer to draw a 2D HUD thats always on top of my WorldWindowGLCanvas. I get the GL out of the DrawContext and try to set the color with
gl.glColor4f(1.0f, 1.0f, 1.0f, 0.4f);

This will set the color to white but the alpha doesn't seem to be working. Does WW have some special way of doing this?

Thanks

Are you enabling blending and setting the gl blend functiion appropriately?

Had a few things commented out that I just assumed were not. Thank you!!
