Utility class that is useful for accumulating error message keys in
action classes or validation methods. Use this class as follows:
- At the beginning of your action class or validation method,
instantiate an instance of this class in a local variable.
- Whenever you wish to add a new error message key, call the
addError() method to add it.
- To return the String array of error message keys required by
other Struts components, call
getErrors().
