JBoss JNDI Naming Question

I wrote a resource adapter and a sample J2EE web application that accesses
the RA. The RA connection pool JNDI name is eis/MyResourceJNDIName. The
resource reference name is eis/MyResourceName. Based on this, the naming
lookup should be java:comp/env/eis/MyResourceName.

The resource reference in web.xml looks like this:

    <resource-ref>
        <res-ref-name>eis/MyResourcePoolName</res-ref-name>
        <res-type>javax.resource.cci.ConnectionFactory</res-type>
        <res-auth>Container</res-auth>
        <res-sharing-scope>Shareable</res-sharing-scope>
    </resource-ref>

The mapping in jboss-web.xml looks like this:

    <jboss-web>
        <resource-ref>
            <res-ref-name>eis/MyResourcePoolName</res-ref-name>
            <res-type>javax.resource.cci.ConnectionFactory</res-type>
            <jndi-name>eis/MyResourcePoolJNDIName</jndi-name>
        </resource-ref>
    </jboss-web>

The ds.xml file configures connection pools like this:

    <no-tx-connection-factory>
        <jndi-name>eis/MyResourcePoolJNDIName</jndi-name>
        <rar-name>my-ra.rar</rar-name>
        <connection-definition>javax.resource.cci.ConnectionFactory</connection-definition>
        <adaptor-display-name>MyResourcePool</adaptor-display-name>
        <config-property name="serverName"
type="java.lang.String">localhost</config-property>
        <min-pool-size>1</min-pool-size>
        <max-pool-size>5</max-pool-size>
    </no-tx-connection-factory>

For some reason, this assigns the JNDI name java:eis/MyResourcePoolJNDIName.
If I change jndi-name to comp/env/eis/MyResourcePoolJNDIName, looking at log
data in the java console, it appears to accept the name, but when I look in
JNDIView, the name is not listed, and the JNDI lookup does not work. Why can't
I enter a value into the expected namespace? All the other appservers
support this.
