IsInfected mailet

[Oki DZ]

Hi,

Recently I received a message and had it forwarded to Postmaster with
the following error:
> Error message below:
> Embedded configuration exception was: No attribute named
> "onMatchException" is associated with the configuration element
> "mailet" at
> file:/usr/local/james2/phoenix/apps/james/SAR-INF/config.xml:99:22

What's the problem? The mailet doesn't need onMatchException or
onMailetException attribute in the config file, does it?

Thanks in advance,
Oki
ps: I attached the message, because I'm still wondering what might have
caused the error.

Hello,

Try adding your class to your web.xml file:

    <servlet>
        <servlet-name>
            automaticProcess
        </servlet-name>
        <servlet-class>
            AutomaticProcess
        </servlet-class>
        <load-on-startup>
            1000
        </load-on-startup>
    </servlet>

Then in your AutomaticProcess class you'd have something like:

public class AutomaticProcess extends HttpServlet implements Runnable {
    public void init() {
        if (!initialized) {
            initialized = initialize();
        }
    }

    protected boolean initialize () {
        Thread thread = new Thread(this);
        thread.setDaemon(true);  // i think this is so the thread will die
when you shutdown the app
        thread.start();
        return true;
    }

    public void run() {
        boolean stop = false;

        while (!stop) {
            // make call to whatever you want to run here

            try {
                Thread.sleep(300000);
            }
            catch (InterruptedException ie) {
                cat.error("AutomaticProcess - " + ie.toString());
            }
        }
    }
}
