Весенняя форма, не заполняющая данные объекту модели

У моего объекта модели есть атрибут CtlgEntry, который имеет атрибут 'YearPublished'. Форма должна быть заполнена, но выбрасывается следующее сообщение об ошибке:Весенняя форма, не заполняющая данные объекту модели

Другие данные загружаются на объект, но только yearPublished бросает ошибку. Ниже приведен код формы Jsp который заполнит деталь catalogueEntry:

<form:form method="POST" action="addCatalogueEntry" commandName="catalogueEntry"> 
     <table> 
      <tr> 
      <td><form:label path="title">Title Of Book:</form:label></td> 
      <td><form:input path="title"/></td> 
      </tr> 
      <tr> 
      <td><form:label path="yearPublished">Year Published:</form:label></td> 
      <td><form:input path="yearPublished"/></td> 
      </tr> 
      <tr> 
      <td><form:label path="isbn">ISBN Number:</form:label></td> 
      <td><form:input path="isbn"/></td> 
      </tr> 
      <tr> 
      <td><form:label path="publisher">Publisher:</form:label></td>

      </tr> 

      <!--<c:forEach items="$catalogueEntry.authorList" var="author" varStatus="status">

       <td>First Name</td> 
       <td><input name="authorList[${status.index}].firstName" id="authorList[${status.index}].firstName"/></td> 
       <%-- 
        <td><form:input path="personList[${i.index}].name" id="name${i.index}" /></td> 
        <td><form:input path="personList[${i.index}].age" id="age${i.index}" /></td> 
       --%> 

      </tr> 
      <tr> 
       <td>Last Name</td> 
       <td><input name="authorList[${status.index}].lastName" id="authorList[${status.index}].lastName"/></td> 
      </tr> 
      </c:forEach> 
      --> 
      <tr> 
      <td><input type="submit" value="CLEAR" /></td> 
      <td><input type="submit" value="SUBMIT" /></td> 
      </tr> 
     </table> 
    </form:form>

методы получения и установки для поля является:.

private Integer yearPublished; 

@Column(name="year_published") 
@NotNull 
public Integer getYearPublished() { 
    return yearPublished; 
} 

public void setYearPublished(int yearPublished) { 
    this.yearPublished = yearPublished; 
}

Используйте не-примитивные типы оберток для этого поля! – NINCOMPOOP

Что такое тип данных 'YearPublished' и каков его метод setter? – NINCOMPOOP

Используйте непримитивные типы оболочки (например, Integer для int, Float для float).

проверьте обновления. Я уже использовал классы-оболочки. Я загрузил данные с помощью метода hibernate persist() в классе тестера, и он принимает и загружает данные в базу данных. –

Можете ли вы сделать это? Public void setYearPublished (Integer yearPublished) '? – NINCOMPOOP

спасибо кучи. теперь работает. –
