Is it possible to use Seam in a JBoss timed service?

java, jboss, seam, service

Solution

There is one way that is a little dirty and there are many developers that would not use such a hack ever but it will solve your problem:

import org.jboss.seam.contexts.Lifecycle;

@Service
public class MyService extends DefaultTimedService implements TimedObject, DefaultServiceInterface {
    @Timeout
    public void ejbTimeout(Timer timer) {
        Lifecycle.beginCall();

        MyInterface loader = (MyInterface) Component.getInstance(MyInterface.SEAM_NAME, true);
        // will not throw no context!
        // also the Component.getInstance(MyInterface.SEAM_NAME, true,true); call
        // is another way you could inject that component. 

        Lifecycle.endCall();
    }
}

I have used it in one project where I couldn't find anything else that worked. If anybody has another solution I am looking forward to seeing it here :).

Problem

I've started to write some new JBoss timed service that was meant to use some existing seam components. But it seems that I can't access these components because of non-existing contexts. Is it possible to use them other than in the typical situation with JSF? A little snippet to demonstrate what I want to do... ``` @Service public class MyService extends DefaultTimedService implements TimedObject, DefaultServiceInterface { @Timeout public void ejbTimeout(Timer timer) { MyInterface loader = (MyInterface) Component.getInstance(MyInterface.SEAM_NAME, true); // throws no context! } } ``` That throws the following exception for example: ``` java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) ```
