When 'finding usages' on a file which is registered in a eg. a hibarenate xml file nb will not show its occurance. Since this case can be generalized there should be an general option added, like (.) include config files (eg. xml, conf, properties...) [_add file type_] Thus nb also looks for the class name in those files
I agree. I guess for such files (with a structure that is unknown to the IDE), refactoring should use a simple fulltext search and replace.
It is already possible. Modules can register own refactoring plugins (RefactoringPluginFactory) to search in custom files. AFAIK the hibernate plugin already exists.
