Introduction. The servlet request manager is an interface whose rendering determines that an object can submit jobs to any resource (eg. html, image, jsp, servlet, etc.) on the server. To inject a response from one servlet into another (i.e. the client receives responses from both servlets)

The RequestDispatcher interface provides the ability to send generic requests to another resource, which can often be an HTML or JSP servlet. This interface can also be easily used to add content related to another resource. This is just one way to work together with servlets.

RequestDispatcher Interface Associated With Methods

1. public void forward(ServletRequest, ServletResponse ServletException, java response) throws.io.IOException: Redirects a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server.
2. public void request, ServletResponse include(ServletRequest response) throws ServletException, java.io.IOException: Includes the contents of the cache (servlet, JSP page, HTML, or file) in the response.

As you can see in each of our illustrations above, the response from the second servlet is often sent to the client. The response Connected to the first servlet is not shown to the user.

As you can see in our own figure above, the response from the second servlet is usually included in the response from the first. a servlet sent to a potential client.

How To Bind An Object To A RequestDispatcher

The getRequestDispatcher() method of the ServletRequest interface returned objects of the RequestDispatcher object. Syntax:

An example of using the getRequestDispatcher method

Query Manager Interface Example

In this example, we will check the password entered by the user. If the password is a servlet, it will pass the appropriate request to the WelcomeServlet, otherwise an error message will be displayed: Sorry, username or invalid username and password!. In this program, we are usually looking for hard-coded information. But you can always check it in the database, which we will see in the Development chapter. In this user-friendly example, we have created some important files:

Index.html file: for this user’s posts.

File Login.java: servlet for handling classes, I would say the answer. If a password is provided, it should forward the request to the authorized servlet.

WelcomeServlet.java file: Servlet for a class that is part of the displays a welcome message.

Web.xml file: Specify a descriptor declaration containing information about the servlet.

index.htmlLogin.javaWelcomeServlet.javaweb.xml

Redirects the request to servlet to an alternative resource (servlet, jsp file or HTML in your file) server. This method allows someone servlet for preprocessing this is a requirement and another resource to create His answer.

For the final result received from RequestDispatcher getRequestDispatcher(), ServletRequest The element path and element parameters are adjusted for a positive match path to the target resource.

forward must be called before a response is received passed to the client exactly (before the output of the response body is flushed). If the answer was already specialized, make these rolls a IllegalStateException.Uncommitted This automatically shrinks the response buffer in front of the front.

The request and response parameters must also match. Objects that have been or will be passed to the dialer servlet service method Subclasses of any ServletRequestWrapper andwhether Classes ServletResponseWrapper holding them.

This The method sets the dispatcher to play the given request DispatcherType.FORWARD.

The servlet manager allows you to forward requests made by one servlet to other servlets. The request manager replacement unit is Send Redirect. With each new request, redirection to the network begins. However, there is a check with the dispatcher inside the network (server).

Example

Let’s explore the concept of a dispatcher-equipped request with a simple example. Consider a task where we have three servlets named servlet1, servlet2 and servlet3. If individuals do not use a dispatcher, when you tell servlet 1 to actually become servlet 1, the server relinquishes control. After that, if we request servlet2, it follows that control will return from the servlet, which is separate from the server, and the server will transfer control when you need servlet2. The server can be in India and the servlet can be requested from America. In this case, the client request should return to the volume The same server (India) that receives the servlet (America). This option is incorrect if there is a lot of traffic between these requests and these responses. The solution to this problem is to use the dispatcher.

In this case, if we turn on the dispatcher, control is transferred from servlet 1 to resolve it to servlet 2 without going back to the host server or involving any network. This view is also known as a servlet chain. It’s called a servlet because my wife and I create a chain of large servlets, chain by chain, from servlet1 to servlet2, from servlet2 to successful servlet3, and so on, and eventually the data server gets the previous servlet.
