This week's book giveaway is in the Agile and other Processes forum. We're giving away four copies of The Mikado Method and have Ola Ellnestam and Daniel Brolund on-line! See this thread for details.
can anybody tell me if there's a standardized way to get access to container wide information inside a typical Servlet container? That is I'd like to create a "manager" web application just like the Tomcat manager application which could be used to gather information about all applications running inside a Servlet container.
I know that the Tomcat manager application runs as a privileged context inside Tomcat and therefore has privileged access to detailed global information. But to my knowledge this is a Tomcat specific facility to manage the whole Servlet container and I wonder if there is a container-independent way to create such a "super application"?!? Or maybe there is a much better way to create a centralized manager application without modifying other applications. Then please let me know, I appreciate any advices!
You should familiarize yourself with the contents of the Servlet Specification (it's an easier read than you might expect). That will tell you everything that's available.
Every container manages things in a different way. Some might use JMX, some are based on OSGi, and so on. I think what you're trying to do is essentially impossible in any generic way without writing a lot of container-specific code. Heck, *external* deployment stuff is all quite different (witness all the Ant/Maven container plugins), let alone *internal*.
Thanks David. I know that the typical specs don't make too much assumptions about implementation details of containers. I just wanted to be sure that I haven't overlooked any features, in particular because there were some efforts to unify container specific deployment issues with the new JEE version 6.
But that's no big deal. I just thought it would be nice to create some kind of container-independent manger application.
