Invoke a method in my application during JBoss start up

[rakeshsagar]

Hi all,

The following is the requirement:

I have an application which I deploy in the JBoss. There is a method in my application which I want to invoke this method while JBoss starts up.

This method basically does some processing and gathers data which will be used once the server is up.

How can I achieve this functionality in JBoss AS 7??

Thanks,

Rakesh

Option1: EJB 3.1

Create a SLSB with annotations @Singleton and @Startup.

An instance of this bean is instantiated on deployment of your application.

In a method annotated with @Init you can do your things.

Option 2: WebListener

@WebListener

public class StartupTimers implements ServletContextListener

{

public void contextInitialized( final ServletContextEvent sce )

{

     // do your job here

}

}

Thanks Frank. We will try both the options.

Thanks

Small correction - It's not a SLSB (stateless session bean), but it's a Singleton session bean.
