Method Details- 
initDescription copied from class:javax.servlet.GenericServletA convenience method which can be overridden so that there's no need to callsuper.init(config).Instead of overriding GenericServlet.init(ServletConfig), simply override this method and it will be called byGenericServlet.init(ServletConfig config). TheServletConfigobject can still be retrieved viaGenericServlet.getServletConfig().- Overrides:
- initin class- GenericServlet
- Throws:
- ServletException- if an exception occurs that interrupts the servlet's normal operation
 
- 
destroypublic void destroy()Description copied from class:javax.servlet.GenericServletCalled by the servlet container to indicate to a servlet that the servlet is being taken out of service. SeeServlet.destroy().- Specified by:
- destroyin interface- Servlet
- Overrides:
- destroyin class- GenericServlet

doGetpublic void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException Description copied from class:javax.servlet.http.HttpServletCalled by the server (via theservicemethod) to allow a servlet to handle a GET request.Overriding this method to support a GET request also automatically supports an HTTP HEAD request. A HEAD request is a GET request that returns no body in the response, only the request header fields. When overriding this method, read the request data, write the response headers, get the response's Writer or output stream object, and finally, write the response data. It's best to include content type and encoding. When using a PrintWriterobject to return the response, set the content type before accessing thePrintWriterobject.The servlet container must write the headers before committing the response, because in HTTP the headers must be sent before the response body. Where possible, set the Content-Length header (with the ServletResponse.setContentLength(int)method), to allow the servlet container to use a persistent connection to return its response to the client, improving performance. The content length is automatically set if the entire response fits inside the response buffer.When using HTTP 1.1 chunked encoding (which means that the response has a Transfer-Encoding header), do not set the Content-Length header. The GET method should be safe, that is, without any side effects for which users are held responsible. For example, most form queries have no side effects. If a client request is intended to change stored data, the request should use some other HTTP method. The GET method should also be idempotent, meaning that it can be safely repeated. Sometimes making a method safe also makes it idempotent. For example, repeating queries is both safe and idempotent, but buying a product online or modifying data is neither safe nor idempotent. If the request is incorrectly formatted, doGetreturns an HTTP "Bad Request" message.- Overrides:
- doGetin class- HttpServlet
- Parameters:
- request- an- HttpServletRequestobject that contains the request the client has made of the servlet
- response- an- HttpServletResponseobject that contains the response the servlet sends to the client
- Throws:
- IOException- if an input or output error is detected when the servlet handles the GET request
- ServletException- if the request for the GET could not be handled
