NAME

Servlet::SingleThreadModel - serialized servlet access interface

CONTENTS

SYNOPSIS

DESCRIPTION

This tagging interface ensures that servlets handle only one request at a time. This interface has no methods.

If a servlet implements this interface, you are guaranteed that no two threads will execute concurrently in the servlet’s service() method. The servlet container can make this guarantee by synchronizing access to a single instance of the servlet, or by maintaining a pool of servlet instances and dispatching each new request to a free servlet.

This interface does not prevent synchronization problems that result from servlets accessing shared resources such as class variables or classes outside the scope of the servlet.

<B>NOTEB>: No provisions have been made for usage of the Servlet API in a threaded environment. This interface is only provided for completeness.
