The thread will execute and finish the process however if there is any response defined for that action it will not occur.

There is no way to know that the client is new or old since by defintion stateless session bean is meant to be stateless. The only way to know is when the information is passed from the remote reference

in jsp-model 1 while developing applicaitons in j sp model 1 archtecture the seperation of roles becomes a tedious issue and code is difficult to maintain like , the jsp developer has to wait for the ...

In model1 there is no separation between the businesslogic and presentation logic, and so we can't reuse the view component.

Presentation's responsibilities are display information to users and interpret commands from use into action upon domain and data source.

buinesslogic's responsibilities are logic upon domain.

to check wheather it is SLSB/SFSB  u can see dd(deployment descriptor).

This is the only place where container checks for it.

Business Tier

As Vishal Told .. It is Exactly Container Specific. Because if u See the Weblogic Server , This will stores/Keeps  the Conversational Info in .Ser files in the One Folder of the 'bea'. Once ...
