Method Detail

init

public void init()
          throws javax.servlet.ServletException

Description copied from class: javax.servlet.GenericServlet

A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding GenericServlet.init(ServletConfig)>GenericServlet.init(ServletConfig) 55 , simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig()>GenericServlet.getServletConfig() 55 .

---

init

public void init(javax.servlet.ServletConfig servletconfig)
          throws javax.servlet.ServletException

Description copied from class: javax.servlet.GenericServlet

Called by the servlet container to indicate to a servlet that the servlet is being placed into service. See Servlet.init(javax.servlet.ServletConfig)>Servlet.init(javax.servlet.ServletConfig) 55 .

This implementation stores the javax.servlet.ServletConfig object it receives from the servlet container for later use. When overriding this form of the method, call super.init(config).

---

doGet

public void doGet(javax.servlet.http.HttpServletRequest httpservletrequest,
                  javax.servlet.http.HttpServletResponse httpservletresponse)
           throws javax.servlet.ServletException,
                  java.io.IOException

Description copied from class: javax.servlet.http.HttpServlet

Called by the server (via the service method) 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 PrintWriter object to return the response, set the content type before accessing the PrintWriter object.

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)>ServletResponse.setContentLength(int) 55 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, doGet returns an HTTP "Bad Request" message.

doPost

public void doPost(javax.servlet.http.HttpServletRequest httpservletrequest,
                   javax.servlet.http.HttpServletResponse httpservletresponse)
            throws javax.servlet.ServletException,
                   java.io.IOException

Description copied from class: javax.servlet.http.HttpServlet

Called by the server (via the service method) to allow a servlet to handle a POST request. The HTTP POST method allows the client to send data of unlimited length to the Web server a single time and is useful when posting information such as credit card numbers.

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 PrintWriter object to return the response, set the content type before accessing the PrintWriter object.

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)>ServletResponse.setContentLength(int) 55 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.

This method does not need to be either safe or idempotent. Operations requested through POST can have side effects for which the user can be held accountable, for example, updating stored data or buying items online.

If the HTTP POST request is incorrectly formatted, doPost returns an HTTP "Bad Request" message.
