Hi Vikas You can make your JSPs thread-safe by having them implement the SingleThreadModel interface. This is done by adding the directive within your JSP page. With this instead of a single instance of the servlet generated for your JSP page loaded in memory you will have N instances of the servlet loaded and initialized with the service method of each instance effectively synchronized. You can typically control the number of instances (N) that are instantiated for all servlets implementing SingleThreadModel through the admin screen for your JSP engine. More importantly avoid using the tag for variables. If you do use this tag then you should set isThreadSafe to true as mentioned above. Otherwise all requests to that page will access those variables causing a nasty race condition. SingleThreadModel is not recommended for normal use.
