Question

将应用程序从jsf 1.1升级到jsf 1.2时，我收到以下错误

    java.lang.ClassCastException: 
    Unable to convert "#{TermsOfUseBean.vin}"
to           type "javax.el.ValueExpression" for attribute "value"
at weblogic.jsp.internal.jsp.utils.JspRuntimeUtils.convertType
    (JspRuntimeUtils.java:150) at 
   jsp_servlet._termsofuse.__termsofuse._jsp__tag20(__termsofuse.java:1102)

下面是tld文件

   <?xml version="1.0" encoding="ISO-8859-1" ?>
   <taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-
     jsptaglibrary_2_0.xsd"
    version="2.0">

     <tlib-version>2.0</tlib-version>
      <jsp-version>2.1</jsp-version>
     <short-name>h</short-name>
      <uri>http://java.sun.com/jsf/html</uri>

编辑2：在jsp

中使用的下面的Tld标记

  Tld tag used in jsp
       <tag>
        <name>inputHidden</name>
        <tag-class>com.sun.faces.taglib.html_basic.InputHiddenTag</tag-class>
                    <body-content>JSP</body-content>
          <attribute>
  <name>converter</name>
  <required>false</required>
  <deferred-value>
    <type>java.lang.String</type>
    </deferred-value>
   <!--<rtexprvalue>false</rtexprvalue>
  -->
   </attribute>

编辑3：JSP代码

       <h:form id="touForm">
            <h:inputHidden value="#{TermsOfUseBean.vin}"
                           id="vin">
            </h:inputHidden>
        </h:form>

编辑4：下面是将名称空间更改为2.1

后的堆栈跟踪

    Static attribute must be a String literal, its illegal to specify an
     expression.
  <h:inputHidden value="#{TermsOfUseBean.vin}" id="vin">
                      ^---^

升级JSF1.2期间的java.lang.ClassCastException
