Question

I\'m not much familiar to Java Currency type, and how it being used in Grails. Though, I\'m yet to use it, I saw a tag to use in the views.

Answer 1

Use the JScience library. It's just a shame it's not in a Maven repo yet, and doesn't have a Groovy wrapper to make it Groovier (TM).

Answer 2

You should use BigDecimal. Groovy and Grails has excellent native support for it as a datatype on GORM domain classes as well. For reasoning behind using it, see here

Answer 5

You might want to take a look a the Currencies plugin. It provides a Money class for holding monetary amounts of differing currencies. They can be embedded into domain classes like so:

    static embedded = ['money']
}
