Example 16 with Servlet

use of jakarta.servlet.Servlet in project tomcat by apache.

the class JspServletWrapper method getServlet.

public Servlet getServlet() throws ServletException {

         * DCL on 'reload' requires that 'reload' be volatile
         * (this also forces a read memory barrier, ensuring the new servlet
         * object is read consistently).
         *
         * When running in non development mode with a checkInterval it is
         * possible (see BZ 62603) for a race condition to cause failures
         * if a Servlet or tag is reloaded while a compile check is running
