[jboss-dev-forums] [Design the new POJO MicroContainer] - Deployer Dependencies

[adrian@jboss.org]

The deployments can now have dependencies.

These are handled by the Microcontainer which calls back into the
MainDeployer/DeployersImpl when dependencies are satisfied.

The dependencies are based on stages like the old relative order:
PARSE - parsing deployers
DESCRIBE (new) - work out dependencies from metadata
CLASSLOADER - classloading construction
POST_CLASSLOADER - aop
REAL - others

While this works, there is still work to do to complete this.

1) It needs an api such that deployers can add dependencies (on the fly).

2) The actual mechanism in the DESCRIBE stage to visit metadata
and discover deployment dependencies does not yet exist.
The first prototype of this will be with the osgi bundle dependencies,
but this needs to be a more generic mechanism.
