This context listener is not specified in TaggerCat's TLD to make it easier to plug in your own implementations.

The Hibernate Session Factory is placed in the application scope as:

Constants.TC_HBN8_SESSION_FACTORY

The Runtime metadata is placed in the application scope as:

Constants.TC_HBN8_METADATA

The Security Provider is placed in the application scope as:
