You should really try to avoid being too clever in a template. Java is
good for doing logical operations. Templates are good for creating
content. Try to keep the business logic in Java.
Btw, to split on '.' in Java you'd need to do "\\.". You need to escape
the backslash so that a literal backslash goes to the regexp evaluator.
But in a template you'd just need something like $mask.split('\.').
Note the use of single quotes!
If you want to use a static method you need to wrap it with an instance
method. As long as you're doing that why not just implement the full
method to do what you need. Make life easier for yourself. Write
yourself a method which does the right thing. And toss an instance of
that object into your Context.

Hello,
I have a simple macro which is supposed to receive a netMask (say
255.255.0.0) and convert it to an inverseMask 0.0.255.255.
The first problem is: how can I split on "."? I tried ".", "\.", "\\."
and so forth but none worked.
The second question is: given a string "128", how can I subtract it
from 255? I tried:
#set( $byte = "128" )
#set( $result = 255 - Integer.parseInt($byte) )
But, velocity doesn't like Integer.parseInt() static method.
Thanks in advance,
