How to display Spring model using Jsp JSTL?

Question

Actually in my spring application have User.jsp and using this Jsp i'm display details.

In my UserProfileForm bean i'm writing

private List<ProfessionalForm> professionalDetails = new ArrayList<ProfessionalForm>();

And ProfessionalForm has another form for details.

In my controller class i'm writing..

 @RequestMapping(value = "user", method = RequestMethod.GET)
    public String user(Model model) throws Exception {
        UserProfileForm form = (UserProfileForm)FormType.USER_PROFILE.getNewInstance();

        model.addAttribute("USER_PROFILE", form);
        return "profile/user";
    }

And my user.jsp page code..

<form:form action="" modelAttribute="USER_PROFILE">
   <div class="answer">
    <c:forEach items="${USER_PROFILE.professionalDetails}" var="professionalForm">
        <jsp:include page="user/professional.jsp">
           <jsp:param value="${professionalForm}" name="PROFESSIONAL" />
        </jsp:include>
    </c:forEach>
   </div>
</form:form>

And this my professional.jsp..

<form:form action="profile/proffessional" modelAttribute="PROFESSIONAL">
<p>
  <label class="control_label">Postion:</label>
    <div class="controls">
        <form:input class="text_midem" path="positionName" />
    </div>
</p>
</form>

But i got follwoing Exception for my Server console..

    SEVERE: Servlet.service() for servlet [spring] in context with path [/EClass] threw exception [An exception occurred processing JSP page /WEB-INF/pages/profile/user.jsp at line 40

Answer 1

使用<％@ include％>代替jsp：include

<%@include file="user/professional.jsp"%>

Answer 2

......
<jsp:include page="user/professional.jsp">
           <jsp:param value="${professionalForm}" name="PROFESSIONAL" />
        </jsp:include>
.......

The above code sends request parameter named PROFESSIONAL to the professional.jsp page and not request attribute . While the below code looks for request attribute

....
<form:form action="profile/proffessional" modelAttribute="PROFESSIONAL">
....

So you need to set the value as request attribute perhaps.

Try the below code

.......

<form:form action="" modelAttribute="USER_PROFILE">
   <div class="answer">
    <c:forEach items="${USER_PROFILE.professionalDetails}" var="professionalForm">
        <c:set var="PROFESSIONAL" scope="request" value="${professionalForm}">
        <jsp:include page="user/professional.jsp">           
        </jsp:include>
    </c:forEach>
   </div>
</form:form>
