Struts adapter is not working-any work round ?

i am trying struts adapter, but having  the following error in 
TranslatorUtil.java
because of

public class PersonForm extends ActionForm {

   private final static SimpleDateFormat FORMAT = new 
SimpleDateFormat("dd.MM.yyyy hh:mm:ss");

   private java.math.BigDecimal _personId = null;
   private java.lang.String _firstName = null;
   private java.lang.String _lastName = null;
