Configure failover for Jboss Seam mail

Question

I need to implement failover functionality for sending mails using jboss seam. I tried to configure two JNDINames in mail-service.xml. But I'm not getting how i can set 2nd JNDI name in code. Also, I'm not getting how can i set smtp host in code. MY Code:

@Name("emailService")  
@AutoCreate  
public class EmailService {  
private static final Log logger = LogFactory.getLog(EmailService.class);  

@In(create = true)  
private Renderer renderer;  

@Asynchronous  
public void sendMessage(@Duration long delay, String template,  
        Object infoNeededForTemplate) {  
    MailSession mailSession = new MailSession();  
    try {  
        Contexts.getEventContext().set("currentMail", infoNeededForTemplate);  
        renderer.render(template);  
        logger.info("Email send to " + ((Mail) infoNeededForTemplate).getToEmail());  
    } catch (Exception e) {  
        logger.error("Error while sending mail: Message = " + e.getMessage());  
        try {  
            renderer.render(template);  
            logger.info("Email send to " + ((Mail) infoNeededForTemplate).getToEmail());  
        } catch (Exception e1) {  
            logger.error("Error while sending mail: Message = " + e1.getMessage());  
        }  
    }  
}

}

My mail-service.xml:

<?xml version="1.0" encoding="UTF-8"?>  
<server>  
<mbean code="org.jboss.mail.MailService" name="jboss:service=Mail">

You can specify the host name explicitly in the Transport.connect method; see the javadocs for details.

Thanks a lot for you reply. As I mentioned in problem, I'm not using Javamail feature but using Jboss Seam. So for me, setting Transport on the fly will not work. I need to either 1. Inject different JNDIName to existing context 2. Inject different host for existing context. If its possible to use Transport object with seam, could you please post some example? Thanks. – Saurabhcdt Mar 13 '13 at 06:26
I don't know anything about Seam so I don't know how it restricts your use of the JavaMail APIs. – Bill Shannon Mar 13 '13 at 19:45
