10. implementation of interface coderanch.com

The container creates an instance of some class that implements HttpServletRequest. We don't have to know exactly what class that is. Knowing that it implements the interface is enough because that guarantees the methods we want to use will be there. If you look at your request.getClass().getName() you'll likely find the container vendor in the package path. When someone decides to ...

11. HttpSessionBindingListener Interface coderanch.com

The HttpSessionBindingListener can be used for objects that you plan to store into your session attributes, so they know when they are attached as a session attribute (with session.setAttribute). In general anything that you would need to do when something when it is placed onto, or removed from a session attribute could do its own handling when it implements this interface. ...

If they are reference varaiables, what do they refernce to? what classes were initialized for ...

15. The Single threadModel Interface. coderanch.com

These things are implemented by the builders of servlet containers (Tomcat, Websphere, etc..) not application developers. How they're implemented is really up to the the container builders and can vary from container to container. Luckily, if this is really of interest to you, there are several popular, open source, containers available for you to study. Tomcat, Resin, and Jetty are the ...

16. HttpSessionListener interface coderanch.com

It's actually a more interesting question than it seems... The javadoc for Servlet 2.4 onwards is indeed as quoted above. However, in Servlet 2.3 it was different - it said that this method is invoked to indicate that the session "was" invalidated. That sounds far more like it's called after the invalidation. In practice there probably isn't much you could safely ...

17. About SingleThreadModei Interface coderanch.com

The STM interface was meant to make servlets thread-safe by making sure that no two threads ran the same servlet instance at the same time. But over time it became clear that this is not sufficient to make web apps thread-safe; there are other concurrency issues (having to do with sessions and context attributes). So it was decided to abandon this ...
