To configure servlet chaining, you need to set up multiple servlets in your web application, typically defined in the web.xml file or through annotations. Each servlet processes requests and can forward the response to the next servlet in the chain using the RequestDispatcher's forward() method. Ensure that each servlet is mapped to a specific URL pattern, allowing the initial request to reach the first servlet in the chain. Additionally, manage the flow by handling request attributes to pass data between servlets as needed.

Difference between servlet engines and servlet chaining?
Servlet engines are software components that manage the execution of servlets, handling requests and responses, and providing an environment for servlets to run within a web server. In contrast, servlet chaining refers to the practice of invoking multiple servlets in a sequence, where the output of one servlet can be passed as input to another, allowing for modular and reusable components in web applications. Essentially, servlet engines provide the infrastructure, while servlet chaining is a design technique for enhancing functionality within that infrastructure.
What is java servlet chaining?
Servlet Chaining means the output of one servlet act as a input to another servlet. Servlet Aliasing allows us to invoke more than one servlet in sequence when the URL is opened with a common servlet alias. The output from first Servlet is sent as input to other Servlet and so on. The Output from the last Servlet is sent back to the browser. The entire process is called Servlet Chaining.
Which one is faster servlet OR jsp?
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.
How jsp is translated to servlet?
JavaServer Pages (JSP) are translated into servlets by the JSP engine during the compilation process. When a JSP file is requested for the first time, the server converts it into a servlet class, which involves converting JSP tags and expressions into Java code that adheres to the servlet API. This generated servlet is then compiled into bytecode and executed, allowing dynamic web content to be served. Subsequent requests utilize the compiled servlet, improving performance.
What is the difference between networking and servlet in java?

Describe the life cycle of servelet?
Each servlet has the same life cycle: * A server loads and initializes the servlet * The servlet handles zero or more client requests * The server removes the servlet (some servers do this step only when they shut down) == When a server loads a servlet, the server runs the servlet's init method. Initialization completes before client requests are handled and before the servlet is destroyed. Even though most servlets are run in multi-threaded servers, servlets have no concurrency issues during servlet initialization. The server calls the init method once, when the server loads the servlet, and will not call the init method again unless the server is reloading the servlet. The server can not reload a servlet until after the server has destroyed the servlet by calling the destroy method. == After initialization, the servlet is able to handle client requests. This part of the servlet life cycle was handled in the previous lesson. == Servlets run until the server are destroys them, for example, at the request of a system administrator. When a server destroys a servlet, the server runs the servlet's destroy method. The method is run once; the server will not run that servlet again until after the server reloads and reinitializes the servlet. When the destroy method runs, another thread might be running a service request. The Handling Service Threads at Servlet Termination lesson shows you how to provide a clean shutdown when there could be long-running threads still running service requests.
What are the applications of servlets?
Servlet is a Server side component, a servlet is a small pluggable extension to the server and servlets are used to extend the functionality of the java enabled server.

Difference between temporary servlet and permanent servlet?
A temporary servlet is started when a request arrives and shut down after the response is generated. A permanent servlet is loaded when the server is started and lives until the server is shut down. * This is useful when startup costs are high, such as a servlet that establishes a connection to a database. * Also useful for permanent serverside service, such as an RMI server. * Provides faster response to client requests when this is crucial. Being temporary or permanent is part of the server configuration.
