      • init

        public void init​(ServletConfig config)
                  throws ServletException
        Deprecated.
        Description copied from interface: Servlet
        Called by the servlet container to indicate to a servlet that the servlet is being placed into service.

        The servlet container calls the init method exactly once after instantiating the servlet. The init method must complete successfully before the servlet can receive any requests.

        The servlet container cannot place the servlet into service if the init method

        1. Throws a ServletException
        2. Does not return within a time period defined by the Web server
        Specified by:
        init in interface Servlet
        Parameters:
        config - a ServletConfig object containing the servlet's configuration and initialization parameters
        Throws:
        ServletException - if an exception has occurred that interferes with the servlet's normal operation
        See Also:
        UnavailableException, Servlet.getServletConfig()
      • getServletConfig

        public ServletConfig getServletConfig()
        Deprecated.
        Description copied from interface: Servlet
        Returns a ServletConfig object, which contains initialization and startup parameters for this servlet. The ServletConfig object returned is the one passed to the init method.

        Implementations of this interface are responsible for storing the ServletConfig object so that this method can return it. The GenericServlet class, which implements this interface, already does this.

        Specified by:
        getServletConfig in interface Servlet
        Returns:
        the ServletConfig object that initializes this servlet
        See Also:
        Servlet.init(javax.servlet.ServletConfig)
      • service

        public void service​(ServletRequest req,
                            ServletResponse res)
                     throws ServletException,
                            java.io.IOException
        Deprecated.
        Description copied from interface: Servlet
        Called by the servlet container to allow the servlet to respond to a request.

        This method is only called after the servlet's init() method has completed successfully.

        The status code of the response always should be set for a servlet that throws or sends an error.

        Servlets typically run inside multithreaded servlet containers that can handle multiple requests concurrently. Developers must be aware to synchronize access to any shared resources such as files, network connections, and as well as the servlet's class and instance variables. More information on multithreaded programming in Java is available in the Java tutorial on multi-threaded programming.

        Specified by:
        service in interface Servlet
        Parameters:
        req - the ServletRequest object that contains the client's request
        res - the ServletResponse object that contains the servlet's response
        Throws:
        ServletException - if an exception occurs that interferes with the servlet's normal operation
        java.io.IOException - if an input or output exception occurs
      • getServletInfo

        public java.lang.String getServletInfo()
        Deprecated.
        Description copied from interface: Servlet
        Returns information about the servlet, such as author, version, and copyright.

        The string that this method returns should be plain text and not markup of any kind (such as HTML, XML, etc.).

        Specified by:
        getServletInfo in interface Servlet
        Returns:
        a String containing servlet information
      • destroy

        public void destroy()
        Deprecated.
        Description copied from interface: Servlet
        Called by the servlet container to indicate to a servlet that the servlet is being taken out of service. This method is only called once all threads within the servlet's service method have exited or after a timeout period has passed. After the servlet container calls this method, it will not call the service method again on this servlet.

        This method gives the servlet an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the servlet's current state in memory.

        Specified by:
        destroy in interface Servlet
      • toString

        public java.lang.String toString()
        Deprecated.
        Overrides:
