> VDF - Virtual Deployment Framework
> ----------------------------------
> VDF registry
> The VDF registry acts as a helper/registry of the VDF contexts.
> Each deployment is made up a top level VDF context
> which might contain sub VDF contexts.
> It does:
> 1) Unpack subdeployments
> 2) Download remote deployments
> 3) Abstract packed/unpacked
> 4) Allow config/registration of url handlers for things like webdav
> 5) Supplying "directory" lists, cf (3) and (4)
> VDF Context
> The VDF context is a replacement for the DeploymentInfo
> of current JBoss it holds the following information:
> name - a name probably a shorted version of the url
> deployer - the identified structural deployer
> logicalURL - the url presented to the user
> physicalURL - the url where it is really located
> parentVDFContext - any parent VDF context (null when top level)
> subVDFContexts - any subdeployments
> classpath - the urls where classes are located
> metainf - the location of any meta data
> manifest - any manifest information
> classloader - constructed by the classloading deployer
> stats/state - e.g. when deployed, the state of the deployment, any errors, etc
> There will be a set of utility methods that provide
> other access, e.g. get me the metadata url for "ejb-jar.xml"
> VDF Context - extensions
> Each structural component can extend the VDF context
> to add more information
> There will also be a "slot" available for each
> deployment component to associate some data with the deployment.
> Context identification
> ----------------------
> A top level deployment must have a structure deployer
> subdeployments that are not explcitly identifed
> (cf Default SubContext processing) that don't have
> deployers are ignored.
> Explicity identified subdeployments must have a
> structure deployer
> Default SubContext processing
> -----------------------------
> All files in the root of the deployment
> are treated as possible subcontexts
