jsp spring-mvc spring-3

Solution 1

Add the following to the top

<%@ page isELIgnored="false"%>

Solution 2

I faced some problem and the above solution worked. But what is the issue ? I run another project, but I don't do this import. But still it works properly.

I'm referring to this solution:

    <%@ page isELIgnored="false"%>

Solution 3

I was mistakenly using the wrong import.

I got import org.springframework.web.portlet.ModelAndView; auto-imported when I thought I had org.springframework.web.servlet.ModelAndView; imported.

It almost drove me nuts.

Thanks.

I am not able to get ${} expression working on my .jsp page.

displayAllCustomers.jsp

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


<html>
    <body>
        <h3>Our Entire Customer Database</h3>
        <ul>
            <c:forEach items="${allCustomers}" var="customer">
                <li>${customer.name}</li>
            </c:forEach>
        </ul>
    </body>
</html>

    <bean name="/displayAllCustomers" class="mypackage.DisplayAllCustomersController">
        <property name="customerManagementService" ref="customerManagementService" />
    </bean>     

</beans>

DisplayAllCustomersController.java

public class DisplayAllCustomersController {

    private CustomerManagementService customerManagementService;
    public void setCustomerManagementService(CustomerManagementService customerManagementService) {
        this.customerManagementService = customerManagementService;
    }

    @RequestMapping("/displayAllCustomers")
    public ModelAndView displayAllCustomers() {
        List<Customer> allCustomers = customerManagementService.getAllCustomers();
        return new ModelAndView("displayAllCustomers", "allCustomers", allCustomers);
    }
}

I am getting only the header "Our Entire Customer Database" displayed when I get the page displayed.

It's driving me nuts and I cant figure out what I am missing.

Could someone please help me understand why is it happening?

Many thanks.
