Hotdeployed components can't be configured through components.xml
-----------------------------------------------------------------

                 Key: JBSEAM-2143
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2143
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0.CR2
            Reporter: Pete Muir
            Priority: Critical
             Fix For: 2.0.1.GA


he hot deployment scanner is isolated, using a URLClassloader that is not available once that method comes to a close. The only way to make this work would be to keep that classloader alive during the rest of the startup process. I can direct you to the line of code that you need to look at if you are curious about it.

Check out lines 540 and 541 or org.jboss.seam.init.Initialiation. The scanForHotDeployableComponents uses the following logic to create a component scanner:

            URL[] urls = { url };
            classLoader = new URLClassLoader(urls, Thread.currentThread().getContextClassLoader());
            paths = new File[] { directory };

Once it processes the classes, that classloader is discarded and obviously, since it is a URLclassloader, the classes aren't going to be found later on.
