How to access model attribute fields in JSP scriptlet?

Question

In my controller I have code like this:

List<FeesReceiptIntegrationModel> FRIList = feesReceiptIntegrationService.listInstituteWiseCollectionSummary(model, request);

model.addAttribute("FRIList", FRIList);

I want to access this FRIList and its fields in Scriptlet of JSP page. I tried something like this:

String fcash = request.getParameter(FRIList.cashamount);

but it does not work.

List myMap = (ArrayList) request.getAttribute("FRIList.cashamount");

I don't want to access this via JSTL tags but I would like to access this only in scriptlet.

Can anybody tell me how this can be achieved?

You put in model list "FRIList", so you can get it in jsp like that: `List myMap = (ArrayList) request.getAttribute("FRIList");` and than do what you want with this list. — glw, Aug 28 '15 at 07:25

@ManojSharma I suppose you use the `spring` framework . Are you using any view templates for your front-end ? — Santhosh, Aug 28 '15 at 08:12

Using scriplets is a bad idea. Try to avoid using java codes inside JSP page.

You can use JSTL c:forEach for your purpose

Simple example

<c:forEach items="${FRIList}" begin="0" end="1" var="test">
${test.cashamount}
</c:forEach>

You cant print the values in the list as it is, you need to iterate them after you get the list from the model. As said,

I don't want to access this via JSTL tags but I would like to access this only in scriptlet

<%  List<FeesReceiptIntegrationModel > myMap = (ArrayList<FeesReceiptIntegrationModel >) request.getAttribute("FRIList");
    for(FeesReceiptIntegrationModel obj : myMap  ){
    obj.getcashamount(); // your getter method here
    }
%>

but it is not advisable to use the scriptlets, please have a look at How to avoid Java code in JSP files?

it gives compile time error Object cannot be converted to FeesReceiptIntegrationModel.. – Manoj Sharma Aug 28 '15 at 08:53
Check my update , you need to cast the object to the bean class – Santhosh Aug 31 '15 at 07:20
