JSF How to spell check on JSF (facelets and bean)

Work in progress...If you have any comment to extend/optimize it please post!

The goal

I want to spell check all *.xhtml and *.java in my JSF application

The solution (incomplete)

find . -name *.xhtml -exec aspell --mode=html -c {} \;

Criticism: EL exressions (e.g. #{fooBean.foo()}) are not skipped by the speller.
