how to access a ModelAndView object within the jsp page

I have a code like this in my controller.

ModelAndView result = new ModelAndView("person/sometrends");  
result.addObject("data", data);  // data -> Map

In my JSP page I have written some Java code that is dependent on the data object. How can I get that data object within the JSP code?

I tried something like this (pseudo code).

<%
    Map x = ${data};
%>

But that doesn't work. Not sure how to access it.

Let me more specific, if you want to use jsp instead of jstl to access the Model you would do something like this:

<% Map x = (Map)request.getAttribute("data") %>

include: <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

and then...

<%
    Map x = ${data};
%>

In a scriptlet, you use the request object like so:

<% Map myMap = (Map) request.getAttribute("data"); %>

If you want to use something like JSTL instead of a scriptlet, you could do:

<c:forEach var="entry" items="${data}">
Name:  ${entry.key} <br/>
Value: ${entry.value} <br/>
</c:forEach>

As Davemeister and novice pointed out, combining EL inside a scriptlet was the root cause of your error.

Using expression language inside the scriptlet would be the cause.
