org.enhydra.servlet
Class ServletContainer
java.lang.Objectorg.enhydra.servlet.ServletContainer
- All Implemented Interfaces:
- com.lutris.multiServer.Service
- public class ServletContainer
- extends java.lang.Object
- implements com.lutris.multiServer.Service
- extends java.lang.Object
Handles requests for Servlets. Multiple connection methods may be routed to one Servlet, or one connection method may direct requests to multiple Servlets (based on URL).
Servlets or Enhydra applications (which are a special kind of servlet) or Servlet 2.2 Web applications may be served.
This class uses a ServletManager to hold a set of Servlets, a ConnectionMethodManager to hold a set of ConnectionMethods, and a FilterManager to hold a set of Filters. These are available to other classes (for example the admin application).
At startup time a configuration file is read, and it describes what ConnectionMethods to create, what Servlets to register, and the connections to make from the ConnectionMethods to the Servlets. It also describes the filters to create and what channels to install them in. These filters are all descendants of the MultServerFilter class.
After this config file is read, and the servlet container is set up, no further action is taken. The thread that ran through start() exits. The ConnectionMethods must create threads, and they are responsible for receiving requests from the outside world and passing them on to the handleRequest() methods of the ServletContainer.
Normally one of the Servlets will be an administration application. This admin app knows about this class, and so it knows how to talk to the current ConnectionMethods and Servlets. It may change the server setup on the fly. For example, it can create and add a new ConnectionMethod. Or it could add a new channel to an already existing ConnectionMethod. Or register a new Servlet. Or add a logging filter to a channel. Or monitor performance.

| Constructor Detail |
ServletContainer
public ServletContainer()
- Default constructor.
| Method Detail |
init
public void init()
- Default initialization. Uses the existing config file if previously
set, otherwise uses the default config file.
init
public void init(java.lang.String configFileName)
- Initialization uses the passed in config file.
- Specified by:
initin interfacecom.lutris.multiServer.Service
start
public void start()
- Start the servlet container.
- Specified by:
startin interfacecom.lutris.multiServer.Service
initialize
private void initialize()
- Get the server ready to read it's config file. All the
manager objects start off empty. There are no "built in"
servlets, connection methods, channels, or filters.
They must all be specified in the config file. This
gives more control to the administrator.
stop
public void stop()
- Stop the servlet container.
This fucnction disables all the channels in all the
connection methods, then destroys all the connection
methods. This causes them to kill all their threads.
When the last thread exits, the java application will
exit.
- Specified by:
stopin interfacecom.lutris.multiServer.Service
getConnectionMethodManager
public org.enhydra.servlet.connectionMethods.ConnectionMethodManager getConnectionMethodManager()
- Get the connection manager for the ServletContainer.
getServletManager
