design question

[Harm de Laat]

Hi all,
I have a J2EE application running in JBoss.
In my application I need some configuration. For instance, we have to email certain recepients when a action occurs. (For instance, when a certain entity bean is removed we have to send an email to a person). In this email we need to have a configurable messagebody, subject, recipients, reply-address etc... etc...
I cannot use the bean environment entries because these only get read at deploy time. I need to be able to change the configuration during run-time.
What would be a good way to make this as configurable as possible?
Thanks for any suggestions!

I don't know if this is the correct answer, but once I did something like this:
in my jboss.xml I added this:

  <resource-managers>
    <resource-manager>
       <res-name>mail/Mail</res-name>
       <res-jndi-name>java:/Mail</res-jndi-name>
    </resource-manager>
  </resource-managers>

I had a class that was in charge only of sending emails. So whenever i needed to send an email (or many emails) I'd invoke this class, and my code did something like this:

public void sendMail()
{
  Session session = (Session)PortableRemoteObject.narrow(new InitialContext().lookup("java:Mail"), Session.class);
  Message msg = new MimeMessage(session);
  msg.setFrom();
  ...
....
}

there was another configuration file in which you added your SMTP sever, so you wouldn't need to hardcode it, but I cant remember which was
I don't know if this is the correct way, it's only a suggestion
