Description _ rkubacki 2003-01-27 08:58:58 UTC

WCO posts mounting task to RP on startup that
fires events when libraries are mounted. This
causes TaglibSupport to check whether it should
add taglib elememnt to DD so it searches for its
object and thus initializes ServerRegistry.
TomcatInstance needs to recognize DO of its
server.xml by loadres.

At the same time WepAppObject is created by
loaders and its initialization waits for WCO lock
to restore its children
