Execute logic at application startup

Question

Hi, I was previously using a servlet init method to write a JMS message to a queue. Since then, I've found that the FacesServlet is final and can't be extended. I know I have an application scope managed bean. Where is the recommended place to put application startup logic in a java server faces web application? I have an MDB reading the queue.
The logic should be executed at deploy/startup to the app server, before any user has accessed the web app.

Answer 1

What I am looking for is how to call a method in my application scope bean, after all the setters have been called.
I have the faces context initializing the beans variables (using the xml file as you indicate). I need a way after all this is done to call an init method or something in my bean to have it do some work before the faces application context makes it available for/to my pages.
I cannot use the constructor because the setters have not been called yet. I cannot do it in a setter because the order of the setter calls is unknown. I need all the setters to be called based on the values I specify in the faces-config.xml and when that completes be able to call a method in the bean to say go set yourself up and get ready for faces to begin calling into your methods.
The spring framework (just one I looked at) has the concept of an xml entry that allows you to specify a method name to call after all the setters have been called and perform any pre startup code you need. I would also like to be able to have a destroy type call in to method prior to the application going away.
I do not know how to do this using the servlet context or if there is some other way to perform this function.
Thanks,
Tony
