I don't think there is anything out of the box to do this. The fmt namespaced tags are about formatting numbers and dates and i18n stuff, but nothing about string formatting. If you don't want to be doing this in your presentation layer with scriptlets or function invocations, you might want to consider adding another model property for the obfuscated CC number that way you can do the formatting in Java where it will be much easier.
