Here's a mini example:
public class Cache
{
private static List myList;
public static void init(Object... someParameters)
{
myList = getTheListFromDB();
}
public static List getList()
{
return myList;
}
}
public class ApplicationBean
{
public List getList()
{
return Cache.getList();
}
}
public class MyServletContextListener implements ServletContextListener
{
public void contextInitialized(ServletContextEvent ev)
{
Cache.init(ev.getServletContext
().getInitParameter("MyDBConnectionInfoOrJNDIName"));
}
}

Hello Steve,
Does it have to be a managed bean? You could probably chose a class with
static methods instead and have the context listener initialize it upon
application startup. You could then create a really lightweight application
bean extracting its data from that class with static members. Forcing a bean
into existence at application startup can be extremelly hard as JSF
VariableResolver requires a FacesContext instance which is based on a
request that you won't have inside the listener to evaluate a value.
