extends Container

An Engine is a Container that represents the entire Catalina servlet engine. It is useful in the following types of scenarios:

In general, you would not use an Engine when deploying Catalina connected to a web server (such as Apache), because the Connector will have utilized the web server's facilities to determine which Context (or perhaps even which Wrapper) should be utilized to process this request.

The child containers attached to an Engine are generally implementations of Host (representing a virtual host) or Context (representing individual an individual servlet context), depending upon the Engine implementation.

If used, an Engine is always the top level Container in a Catalina hierarchy. Therefore, the implementation's setParent() method should throw IllegalArgumentException.
