I've not done anything with EJBs and I'm not sure what exactly you mean by
static "properties". I have however dealt with reducing instantiations in
servlets. I simply created a BeanBag class with static methods to each one
of my beans; these are not "proper" beans, but where simply objects that
were formerly used in JSP via the jsp:useBean directive.
Here is the general pattern:
class BeanBag {
private static SomeBean someBean = null;
public static synchronized getSomeBean() {
if (someBean == null) someBean = new SomeBean();
return someBean;
}
}
I have now numerous Servlets, JSPs and POJOs that use BeanBag to obtain
singleton instances of my beans. Its worked great for me.
