Shawn is rarely wrong, but here actually missed one detail: JSP 2.0 adds
_functions_ to the EL, but not _methods_ as is used in this example.
A function is a method on a specific class, declared in the TLD. It can
then be used in an EL expression like this:
${mylib:customer(mybean, pageScope.range * 2)}
