as we know static accessors are used to check the number of instance to one and also global copy for all objects of the class. But when the program enters environment where you have different class loaders. .like web application servers its bit tricky and I have faced problems in JRun 4.
So its always better to manage this restrictions in our code uring Singleton pattern.

If somebody could give the fundamental differences of the two approaches, it is even better.

I am to decide between two possible implementations viz.: 1. use a class with some static properties and some static accessor methods which can be accessed by any JSP/servlet thread. The shared (application ) object will be there in the static property and will be accessed by the static methods. 2. use ServletContext's getAttribute() and setAttribute() methods. I want to know which method is a better approach for a web site with possibly 3000 concurrent users? Thanks in advance.
