VelocityMenuDisplayer init SEVERE: Error initializing Velocity

I am getting these errors trying to display a simple Velocity menu.
I've got the tabbedmenu working, but the same menu won't display with
velocity MenuDisplayer.
I've added the globalMacros.vm, template, css and script to the project. 
Looks like something is still missing... Any idea?
Thanks,
Roman.

Below, I've attached my .jsp page and weblogic log with errors.

String path = request.getContextPath();
