Re: MVC Issue

[Sachin S. Khanna]

What makes you believe that the Controller Servlet in the MVC model has to be a Singleton Class. Another thing as per my limited knowledge having a singleton class doesn't mean that it implements a SingleThreadModel interface.It only means that whenever the static getInstance method of the class is called only one instance would be returned and the Class has a private constructor which helps in achieving the above mentioned behaviour. The performance of an application could suffer if the Controller Servlet implemented the SingleThreadModel interface in my opinion. Looking forward to your (Mr. Sandhu) as well as others comments. Have a nice day. With regards, Sachin S.

As the controller servlet is a singleton class (implements single thread model) i.e. two threads cant call the service method concorrently. so no two clients can call the same process method of the request handler. you can say Servlet works as a synchronizing agent. (Or actually synchronization never takes place/ reqiured ).   Cheers!! raj   -----Original Message----- From: Sachin S.

I'd like to know if there is a need to synchronize this method. Looking forward to your comments. Have a nice day. With regards, Sachin S. Khanna http://www.emailanorder.com
