JSPs not displaying objects from model in Spring

Question

I have what should be an easy issue to solve, but I\'m having no luck.

In my servlet-servlet.xml file, I have the following beans (in addition to others):

Answer 1

I haven't used quite as much annotation configuration as you have with Spring MVC, so I'm not sure of all the things that are being automatically done with your setup. My only thought is this: should the method parameter be a ModelMap object? The examples I've seen before have all used ModelMap as the parameter type. Section 13.11.3 of this page is one of them: http://static.springsource.org/spring/docs/2.5.6/reference/mvc.html.

Like I said, I haven't used this type of auto-configuration before -- I do it slightly more manually, and extend my controllers from something like an AbstractController or a SimpleFormController.

I ran into the same problem, and after comparing 2 similar apps (one with EL working fine and the other not), noticed that the problem on my tomcat 7 depended on the webapp version specified in the web.xml of the application.

The same jsp using Web App 2.3 displays ${someMessage}. (BTW, this is what you get using maven archetype:generate with archetypeArtifactId=maven-archetype-webapp).

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
...

The same jsp using Web App 2.4 displays the model object properly:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="webapp-id" version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
...

Hope that it helps!

Are you sure that evaluation of EL is enabled in your JSP? I sometimes had the problem, that it got turned of somehow. Try evaluating a simple expression like ${'test'} and see if 'test' appears.

You can also try enabling it with page directives or something else if EL should be disabled.

<%@ page isScriptingEnabled="true" isELIgnored="false" %> //of course it has to be FALSE

(Sorry, I can't remember if this 100% correct. It might be 'isELEnabled')
