validate method with resource file reference?

[Liz Brown]

I have following validate. I have a resource bundle i need to give since my application has more than 1 properties files. How to mention it here?

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request){
ActionErrors errors = new ActionErrors();

if(newId==null || newId.trim().equals("")){
errors.add("newId",new ActionError("userRegistration.newId.problem"));
//this is a key, put the value i.e. the message in properties file
}




return errors;
}
