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 = ;
            classLoader = new URLClassLoader(urls,
Thread.currentThread().getContextClassLoader());
            paths = new File[] ;

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.

----------------------------------------

Does this mean that in the future release components that is
configured through components.xml will be able to be hot
deployed?

-----------------------------------

In some form, yes. Possibly you will need a separate
components.xml that is hot deployable
