Can you please try like this in your cotroller and see if this works...

@RequestMapping(method = RequestMethod.GET)
public ModelMap printWelcome(ModelMap model) {
......
......
return model;
}

Thanks Vivek SharmaJi didnt work, returning the modal or return the name of the JSP page did not make a difference it can resolve strings an objects, seems to be having problems with the collections.

But thanks for your input.

Yeah, to me also code looks fine. I was thinking if somehow 'model' is being lost.

Also, can you please try using following as well on jsp page and see the result.

<c:out value="${fund.fundName}"/>

I'm having trouble reading your code with all the wonky indentation. But I do not see how your JSP could possible be printing out those labels when they do not exist in the HTML. Are you posting the real code? Or just paraphrasing it?

What is the HTML that is rendered to the browser? (View Source)

It looks like the collections are there its just not interating over them

Seeing html it seems tld is not being resolved it should not print as follows, it should be resolved.
<c:forEach var="fund" items="

Hence please check following import and your application is able to find jstl tag lib.

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
