a unique context should be created for each user

I am planned to design non EJB application, I explain my scenario.

When a new user comes in, a unique context should be created for each user. And place large number of objects in the context. How to design and which design pattern should be followed.

Any suggestion really welcome

Such a construct already exists. It's called a session and is implemented via the HttpSession interface.

thanks for reply,I have idea about session,I like to have effective usage of session object,if large object saved in session performance may lost.

if large object saved in session performance may lost.

If you are worried about that, make sure that object is Serializable, then the servlet container can write it out to disk and recover it later.

hello William

Any framework(like struts ,spring) available for effective handling of session in web application,That framework should handle all boilerplate code.I will write the business necessary for me.

You appear to be under the impression that session handling is some big difficult deal and some magic framework will keep you from making a mistake.

IMHO, the servlet API is all the framework you need and it is up to you the programmer to understand it.

What boilerplate code? There's session.setAttribute() and session.getAttribute(). This is all you need for almost every web app you write. Every framework would still need getters and setters on a context.

Every framework

Can you write those frameworks name?

Why should anyone take the time to write own the name of every Java application framework? Just google for them!

Besides, what purpose would that serve in the context of your original question?

I wasn't referring to one in particular. I suppose I should have said "any framework" rather than "every framework."
