Error: Cannot set org.jboss.seam.mail.MailSession field!

[allforjava.allforjava.aol.in]

Dear Team,

I'm gettting the above error towards:

@Name("mailer")
@Install(precedence=Install.FRAMEWORK)
public class Mailer {
     @In
     MailSession mailSession;
     
     @Logger
     private Log log;
     
     public void sendMail() {
          
          try {
               System.out.println("mailSession.getSession(): "+mailSession.getSession());
               log.debug("VALUE: Mailer.sendMail():",mailSession.getSession());
               Message message = new MimeMessage(mailSession.getSession());

.
.          } catch (Exception e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          }
     }
}

And component.xml:

     <mail:mail-session
               host="myHost.com"
               password="password"
               port="25"
               username="emailId"/>

Please assist to resolve it. Thank you in advance.
