JNDI lookup for mail Session on Glassfish

[arsenalist]

I'm trying to configure my app to make a JNDI lookup in Glassfish when using Seam's mail component and I keep getting the following exception:

java.lang.ClassCastException: com.sun.enterprise.deployment.MailConfiguration cannot be cast to javax.mail.Session

My configuration is as simple as this:

|<mail:mail-session session-jndi-name="mail/local" />|

And I have created a |mail/local| resource under JavaMail Sessions in the Glassfish console.

If I use a Seam configured mail session using the following, it works fine:

|<mail:mail-session host="postoffice139.utcc.utoronto.ca"/>|

Any ideas what's wrong? I'm a little confused because the JNDI lookup is succeeding, it's just returning the wrong type of object.  It's not like I"m getting a NameNotFoundException when doing the JNDI lookup.  Is my |<mail:mail-session> configuration correct>|

This message formatted funny for some reason, please ignore all the | characters in there...

I figured this out, needed to add the following in web.xml:

    <resource-ref>
        <res-ref-name>mail/local</res-ref-name>
        <res-type>javax.mail.Session</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

and change component configuration to:

<mail:mail-session session-jndi-name="java:comp/env/mail/local" />
