Since this came up in the top of my google search on this topic it seems like folks might like to see an updated answer when they get this on the top of their search...
(found this here: http://velocity.10973.n7.nabble.com/Use-of-static-functions-td15126.html)
in Velocity 1.5 or earlier, you can just use:
#set( $String = '' )
#set( $foo = $String.format('%.1f', $dataFedIn) )
because you can always call static methods on instances. :)
however, since there are some static classes of which you cannot
create instances (e.g. java.util.Math), we added support in 1.6 for
static class methods sans instances:
Java:
context.put("String", String.class);
Velocity:
#set( $foo = $String.format('%.1f', $dataFedIn) )
