As in topic: Does component configured by components.xml must be in main classloader?

It will by probably simple question for most of you but I didn't manage to find official statement in documentation nor in Seam in Action. Maybe I do something wrong, but when I'm trying to configure component from hot-deploy classloader in components.xml, I'm getting an excetpion:

java.lang.ClassNotFoundException: No ClassLoaders found for: <hot-deploy class name>

When this class is in main classloader, everything works fine.

What is the main classloader? It most likely needs to be in your app server's classpath, so for JBoss that is the EAR/WAR package or the server/default/lib, for example...

No, you can't wire components from components.xml that are in the hot deployment classloader. The hot deployment classloader is isolated, so that every time a hot deployment occurs it can be dropped and re-created.

It is in section 2.8 of the seam docs.

What is the "main classloader"?

Sorry, Arbi, I wasn't clear. I just used JBoss Tools terminology where there are hot and main source directories.

It is in section 2.8 of the seam docs.

Yeah, your're right. I missed it :(. Thanks for answers.
