Welcome to JavaRanch! We're glad you're here. I do need to remind you, though, that the name you are currently displaying does not meet the guidelines of the JavaRanch Naming Policy. In particular, the name you display must be a first and last name, and must not be obviously fictitious. Please change the Publicly Displayed Name in your user profile so that it meets the guidelines.
This may seem trivial to you, but it's an important part of the culture at JavaRanch, and we do appreciate your compliance with it.
Regarding your question: I'm afraid I don't understand very well what you're asking. Why can't you use files like ApplicationResources.properties? If you want to use LookupDispatchAction, you don't have any choice but to use resource properties files.
