How many objects exist when a JSP has concurrent requests?
JSP documents are compiled to servlets when they are placed in service and operate like standard servlets. Usually a single JSP servlet instance is used to serve any number of virtually simultaneous requests, so only one servlet object exists. Where your servlet is composed of several other objects, the single servlet instantiates a single set of supporting objects. If your JSP servlet declares the page directive isThreadSafe=”false”, the servlet container may create a pool of instances to handle concurrent requests independently. In this case, the number of supporting objects would be multiplied accordingly. Actions: Follow-up, clarify or correct this answer. Submit a new question.
