Question

IN JSP i used to put things in bean’s constructor which is in APPLCIATION scope,
similarly
i want to load a function upon deploy of application where i can put .

i tried putting in listener but @ that time i am not getting faces config ‘s injection .

so is there any way out ?

Answer 1

Tt sounds suspicious that the listener hadn’t worked for you. It should’ve worked. What I assume has happened is that you expect your request-scoped beans to get their dependencies injected outside a request/response cycle. Well, this won’t happen.

So you’d better do one of these:

• put the @PostConstruct annotation on every bean and initialize it.
• register a ServletRequestListener which gets triggered on each request

If you want a managed bean to initialize something application-wide (what is that something, btw):

1. Create a managed bean with scope application
2. Do your initialization in a method annotated with @PostConstruct

Btw, you have been wrong to put JSP initialization code in constructor. It should’ve been in the init(..) method. (and actually, shouldn’t have been in a JSP at all)

Alternatively you can use a PhaseListener (in the faces-config.xml), where to lazily load tha application settings.
