@Resource annotation not working properly with JBoss5.0.1

I'm tring to deploy my app in JBoss 5.0.1. Some of my beans in this app are using @Resource annotations. If i understood the problem, my guess is JBoss is tring to process this annotation before spring-core. And i noticed that "Mapped-name" is mandatory for JBoss implementation of @Resource annotation.

I just ran into this mapped-name exception problem. What fixed it for me was using an older version of the Web Application schema.

I changed my web.xml from this:

<?xml version="1.0"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
...
</web-app>

To this:

<?xml version="1.0"?>
<!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>
...
</web-app>

I just got this problem too. I'm using JBoss 5.1.0-GA

On my case the problem was that javaee-api-5.jar library was being packaged into my application (ear).
This library was in conflict with Jboss libs.

Just remove javaee-api-5.jar (or similiar one) from your application.

Using maven, you can add an exclusion:

<exclusion>
        <groupId>javaee</groupId>
        <artifactId>javaee-api</artifactId>
</exclusion>
