無法設置屬性_託管bean _ JSF 2.0

2012-08-02 70 views

我想創建一個基本的表與JSF 2.0發送「時間表」條目到數據庫。我寫我的豆與getter和setter方法的所有領域，並設法通過的faces-config中的豆，但我一直運行到錯誤：
"com.sun.faces.mgbean.ManagedBeanCreationException: Unable to set property monday1 for managed bean timesheet"無法設置屬性_託管bean _ JSF 2.0

屬性名稱是無關緊要的，它只是在上市首財產在faces-config中。我的整個屬性都不起作用。

下面是HTML/JSF表：

<h:form> 
      <table> 
       <thead> 
        <tr> 
         <th>Employee Details</th> 
         <th id="reqBox" colspan="2"> 
          <span class="reqStar">*</span> 
          <span class="reqText">Required Field</span> 
         </th> 
        </tr> 
       </thead> 
       <tbody> 
        <tr> 
         <td> 
          Employee ID <br /> 
          <input name="empID" type="text" value="#{userBean.id}" readonly="readonly"/>

         <td>

          <input name="empName" type="text" value="#{userBean.firstName} #{userBean.lastName}" readonly="readonly" /> 
         </td>

<managed-property> 
    <property-name>monday1</property-name> 
    <property-class>int</property-class> 
    <value/> 
</managed-property>

您還沒有指定有效的int值作爲託管屬性值。有效的int值是在Integer.MIN_VALUE到Integer.MAX_VALUE範圍內的數字。空字符串或空值不是有效的int值。這些都是非法的論據。

解決您的問題，要麼使之<value>0</value>

<managed-property> 
    <property-name>monday1</property-name> 
    <property-class>int</property-class> 
    <value>0</value> 
</managed-property>

或者只是刪除的<managed-property>乾脆依靠0標準的Java int默認。順便說一下，我還懷疑所有那些其他無價值管理的房產。他們看起來似乎毫無用處。實際上，整個<managed-bean>條目似乎毫無用處，因爲您可以使用JSF2 @ManagedBean註釋。

嗨BalusC我使用JSF2 @ManagedBean註釋，我沒有faces-config.xml仍然我有同樣的問題com.sun.faces.mgbean.ManagedBeanCreationException：無法設置託管bean的屬性homeBean CtyBen – 2013-05-18 04:20:30
