javax.servlet.http.HttpServlet.service(HttpServlet.java:803)请问有可能那里出现问题！骨灰们给个提示

解决方案 »

  1.   

    Property 'productId' not found on type java.lang.String 
      

  2.   

    Property 'productId' not found on type java.lang.String 
    你看看你后台代码中有没有productid属性，还有看看是不是string类型的
      

  3.   

    问题已经找出了，谢谢大家的回复
    <c:forEach var="p" items="{reqeustScope.products}"> 
    改成
    <c:forEach var="p" items="${requestScope.products}"> 
    这类问题出现基本上是EL表达式的错误
