<jsp：param>抛出NullPointerException </jsp：param>

Question

我在Weblogic Server中获取NullPointerException，同时在jsp中更改以下更改：

    <jsp:include page="Nav.jspx">
        <jsp:param name="invoiceType" value="${invoiceTypeLong}"/>
        <jsp:param name="current" value="Header"/>
    </jsp:include>

我已经给出了将上述代码修改为下面提到的安全实现代码的说明。两个代码片段在tomcat中工作正常，但是下面提到的weblogic代码给出了NullPointerException。

   <jsp:include page="Nav.jspx">
        <jsp:param name="invoiceType"> 
            <jsp:attribute name="value"> 
               <c:out value="${invoiceTypeLong}"/> 
            </jsp:attribute> 
         </jsp:param>
        <jsp:param name="current" value="Header"/>
    </jsp:include>

如果我需要更改任何配置文件或原因是什么，有人可以建议我吗？
