jboss-web.xml validation error

Question

Why do i have a validation error on the element "resource-ref" in this very simple jboss-web.xml file?

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-web_6_0.xsd"
    version="6.0">

    <resource-ref>
        <res-ref-name>jdbc/RoadsDB</res-ref-name>
        <jndi-name>java:/RoadsDB</jndi-name>
    </resource-ref>

</jboss-web>

If i put the xml declarations away like this, i have no problem deploying my app:

<jboss-web>

    <resource-ref>
        <res-ref-name>jdbc/RoadsDB</res-ref-name>
        <jndi-name>java:/RoadsDB</jndi-name>
    </resource-ref>

</jboss-web>

I would just like to know what the problem is.

This appears to be because JBoss does not like to parse the schema definitions if you put them in your jboss-web.xml file, even though it is perfectly valid XML. So if you want to add the definitions so tools like the Eclipse XML editor can use them, you're out of luck unless you remove them again before deploying your app.

Maybe somebody from the JBoss AS team can comment.

FWIW, here's the error you get on JBoss 6.0 Final if you include the schema definitions.

That's because resource-ref doesn't exists with schema jboss-web_6_0.xsd. These are the following elements valid for jboss-web_6_0.xsd.

<xsd:sequence>
    <xsd:element name="class-loading" type="jboss:class-loadingType" minOccurs="0"/>
    <xsd:element name="security-domain" type="jboss:security-domainType" minOccurs="0"/>

    <xsd:element name="context-root" type="jboss:context-rootType" minOccurs="0"/>
    <xsd:element name="virtual-host" type="jboss:virtual-hostType" minOccurs="0" maxOccurs="unbounded"/>
