How can I call doGet method?

[Nuha Iqbal]

Hi,

I am beginner to JAVA and I have the following doGet method, and I need to call to from another method

public void doGet(HttpServletRequest request, HttpServletResponse response)            
 throws IOException, ServletException     
 {         
String url = "";         
//if the number is minus n does not exist        
 if (Code < 0 )         
 {             url = "/Error.jsp";         }         
//if the number is not included         
else          {             url = "/Error.jsp";         }          
 // forward to the view         
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);         
dispatcher.forward(request, response);     }

I want to know how to call this method from another method, just like the following.

public int getCode()     
{        
 if (stateName.equals("Aden") || stateName.equals("aden") || stateName.equals("ADEN"))         
{             Code = 01;             return (Code);         }         
else if (stateName.equals("Mukalla") || stateName.equals("mukalla") || stateName.equals("MUKALLA"))        
 {             Code = 02;             return (Code);         }         
else         {           return doGet(request, response);         }     }

the line
return doGet(request, response);
I want to know the correct way of calling?

Hi Nuha, welcome to JavaRanch!

While it's possible to make a direct call to a servlet's doGet() method, it's probably not going to be useful to do that. Servlets are meant to be deployed into a servlet container, like Tomcat, JBoss, or WebLogic. The doGet() method is called automatically by the framework to handle an incoming GET request, usually from a web browser. The method either writes directly to the response's output, which then renders back on the browser, or it forwards the request to another URL to be handled there.

Hey,
Please tell the reason why you want to call doGet from another method.

The Service method would invoke doGet() or doPost() depending on the equivalent (GET/POST) HTTP methods. If your servlet should handle both POST and GET HTTP method you ll call doGet from the doPost method.

Though it should be mentioned that handling GET and POST in the same way is considered a poor practice those days.

I'd go further than that - the HTTP specification is clear on the fact that GET and POST have different characteristics, and should be used in different circumstances. Any design that uses them interchangeably may cause suboptimal (or downright broken) behavior in the presence of HTTP intermediaries like caches, proxies and the like.

Thanks for sharing the valuable information.

Hi,

You can try with HttpsURLConnection which will send the request to the method from Java Programme.
