请教，一个关于<jsp:include>的问题（急！！）？

Question

<%
String id="202";
%>
<center>
             <span>
                <%=id %>//a
                      <jsp:include page="customer_view.jsp?CustomerId=<%=id %>&opt=view" /> //b
     //<jsp:include page="customer_view.jsp?CustomerId=<%=id %>&opt=view" flush="true" />//c
               </span>
</center>customer_view.jsp页面上要用的字段CustomerId是支持String的
当包含语句用c处的时候，我的程序在a处有显示，但是c处没有结果，
当包含语句用b处的时候，就会有异常
