我有一个JSF托管bean

当从WebSphere AppServer中的JSF页面引用托管bean时,我收到错误.

<h:inputText value=#{bean}/>

bean在faces-config.xml中定义为

<managed-bean>
  <managed-bean-name>bean</managed-bean-name>
  <managed-bean-class>com.test.Bean</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

这是例外:

com.sun.faces.mgbean.ManagedBeanCreationException:在托管bean mailingCitySuggestions上执行资源注入时发生错误

更新:这是堆栈跟踪:

 com.sun.faces.mgbean.ManagedBeanCreationException: An error occurred performing resource injection on managed bean mailingCitySuggestions

我们可以在HTML标记中使用JSF EL吗？例如,在纯HTML <td>元素中,我们可以使用EL #{bean.color}作为bgcolor属性吗？

<td bgcolor="#{bean.color}">

如何构造一个不包含一组字符串的正则表达式.

对于此示例,我想验证地址行1文本框,以便它不包含任何辅助地址部分,如'Apt','Bldg','Ste','Unit'等.
