Advance java session 4
Client-side redirection uses response.sendRedirect() to instruct the client's browser to make a new request to a different URL. Server-side redirection uses the RequestDispatcher to forward or include content from another resource on the server. Forwarding transfers control to the new resource, while including renders the output of both resources. Redirection is commonly used for load balancing and sending clients to new locations.

SCWCD 1. get post - url (cap1 - cap2 )
The document provides an overview of key concepts in web development including HTTP methods (GET, POST), the servlet lifecycle, the web container, the web.xml deployment descriptor, and URLs. It describes the benefits and features of GET and POST requests, how the container manages servlets and JSPs, how the web.xml file configures servlets without code changes, and the components of a URL.
React js use contexts and useContext hook
The document discusses the useContext hook in React. It explains that hooks are special functions that start with "use" and are analogous to class component methods. The useContext hook allows components to access data from their parent context without having to pass props down through each level. Without useContext, data would need to be passed through props from the parent component to child components. With useContext, a Context Provider wraps components and provides a value that can be accessed using useContext in any child component without passing props.
Request dispatching in servlet
Request dispatching allows one servlet to forward a request to another servlet, JSP, or HTML page for further processing. This is done using a RequestDispatcher object, which can be obtained from the servlet context or request object. The RequestDispatcher's forward() method dispatches the request without the client's knowledge, maintaining request parameters, while include() dispatches and includes the response in the original response without changing headers.
Lecture 2
The document discusses servlets and how they work. Servlets are server-side Java programs that generate responses, usually in the form of HTML pages, to requests from web clients. Servlets run within a servlet container, which manages loading and executing servlets in response to requests. Servlets can access request parameters and session information, generate dynamic content, connect to databases, and more. Common methods include doGet() and doPost() to handle different HTTP request types.
Corespring
The document introduces Spring's application context and XML-based configuration language. It demonstrates how to define beans and their dependencies, and how Spring manages the lifecycle by fully initializing beans before they are used, based on their declared dependencies. It shows how to create an application context which acts as a container that encapsulates the beans and conceals implementation details.
Node js crash course session 3
This document provides an overview of query parameters and error handling in Node.js and Express. It discusses:
- What query parameters are and how they are accessed in Express using req.query
- Examples of simple and complex query parameters
- The difference between query parameters and route parameters
- How Express handles errors thrown in route handlers and middleware, either synchronously or asynchronously
- Setting error status codes when sending error responses

Retrofit
Retrofit is a type-safe REST client library for Android and Java that allows defining REST APIs as Java interfaces. It simplifies HTTP communication by converting remote APIs into declarative interfaces. It supports synchronous, asynchronous, and observable API consumption. The Retrofit library was created by Square.
React
React is a JavaScript library for building user interfaces. It uses a component-based approach where UI is broken into independent, reusable pieces. The key principles of React include breaking UI into components, unidirectional data flow, identifying UI state, and dispatching actions to change state. React uses JSX syntax which resembles HTML but integrates JavaScript. Components can be "smart" or "dumb", with smart components providing data and dumb components displaying it. Redux is often used with React to manage state in a centralized store using actions and reducers. Debugging tools like React Developer Tools and Redux DevTools help develop React applications.
Servlet Filters
Filters are used to process requests and responses in servlets. Filters intercept requests before they reach servlets and responses after they leave servlets. This allows filters to perform functions like authentication, logging, compression, and more across multiple servlets. To create a filter, we implement the Filter interface and define init(), doFilter(), and destroy() methods. The doFilter() method contains the main filtering logic and can pass the request and response to the next filter or servlet in the chain. Filters are configured in web.xml and can be chained to customize request and response processing.
React context

React js t7 - forms-events
The document discusses working with forms and events in ReactJS. It explains that HTML input elements like <input>, <textarea>, and <select> have their own state and need to be updated using the setState() method when a user interacts. Events in ReactJS work the same as in JavaScript and all JavaScript event handlers can be used. The setState() method is used to update state when a user interacts with an HTML element. An example component is provided that manages form state with an input field and button that updates state on change and click events.
Android rest client applications-services approach @Droidcon Bucharest 2012
This document discusses approaches for building Android REST client applications. It describes using a services approach where an activity sends a request to a service, which then performs the request in a worker thread. The service notifies listeners of the response. It recommends using loaders to handle configuration changes, where a custom loader binds to the service, performs the request, and returns the response to the activity. The service processes requests asynchronously using AsyncTask and delivers responses via a pipeline that analyzes and converts the data.
Multiprocessing.pptx
A process is a running program with a unique ID that can be retrieved using os.getpid(). Processes can have child processes with IDs retrieved by os.getppid(). Multiprocessing allows a system to run multiple processes simultaneously. The Process class is used to create processes that execute target functions. Process synchronization prevents race conditions when accessing shared resources through critical sections. The Lock class manages access to shared resources across processes. Threads are sequences of execution within a process that can improve program throughput.
Active mq read and write flow in mule
This document provides a tutorial on integrating Apache ActiveMQ with MuleSoft Mule for messaging. It describes creating two flows - a write flow that uses an HTTP inbound endpoint to send messages to an ActiveMQ queue via a JMS outbound endpoint, and a read flow that uses a JMS inbound endpoint to receive messages from the queue. It includes code examples and steps for setting up the project and running the sample application.
Servlet life cycle
The servlet lifecycle consists of 5 steps: (1) loading and instantiation of servlets by the servlet container, (2) initialization via the init() method, (3) processing of client requests via the service() method, (4) finalization via the destroy() method, and (5) garbage collection. The service() method handles each client request by dispatching to doGet() or doPost() depending on the request type, while init() and destroy() are called once per servlet instance.
Sse
The document summarizes Server-Sent Events (SSE), which allow for a server to push data to connected clients in real-time. SSE connections automatically reconnect if dropped, reuse existing connections, and avoid blocking other HTTP traffic. SSE are supported in all major browsers except Internet Explorer. The document provides examples of how to receive SSE notifications on the client and send data from the server using SSE.
Starting with Reactjs
This document provides an introduction and overview of ReactJS. It discusses that React is a JavaScript library developed by Facebook and Instagram for building user interfaces. It introduces key React concepts like components, props, state, lifecycles, and differences between imperative and declarative programming. It also covers setting up a basic React project using tools like Webpack and Babel and references additional React resources.
Servlet lifecycle
The servlet lifecycle consists of four main steps:
1) Loading and instantiation where the servlet class is loaded and an instance is created.
2) Initialization where the init() method is called to perform initialization.
3) Request handling where the service() method handles client requests.
4) End of service where the destroy() method is called before the servlet is removed from service to clean up resources.
The main lifecycle methods are init(), service(), and destroy(). The init() method performs initialization, service() handles requests, and destroy() performs cleanup before removal.
Ajax and xml
Ajax allows asynchronous communication between a browser and server to update parts of a web page without reloading the entire page. It uses a combination of technologies including JavaScript, HTML, CSS, XML, and HTTP. The XMLHttpRequest object is used to asynchronously send and receive data from a web server in the background without interfering with the display and behavior of the existing page. This allows for faster and more interactive web applications.

React js t5 - state
State in React is a JavaScript object that contains private data for a component. The state data can be used to render a component and is initialized in the constructor method. For example, a Hello component defines a msg property in its state that is rendered in an h1 tag, displaying the message "Hello, RTDL - Tutorials!" on the page.
Rest Service In Mule
Rest services in Mule can be implemented in two ways:
1) Using APIkit which creates APIs based on RAML definitions and produces a Mule application with HTTP endpoints and exception strategies.
2) Using a REST component which publishes RESTful web services via JAX-RS annotations and Jersey, specifying the REST component class.
REST services consume resources represented as JSON or XML via HTTP methods like GET, PUT, DELETE, and POST. REST clients can be created to call RESTful services within Mule applications or using connectors generated with the DevKit.
Introduction to React JS for beginners
- React is a JavaScript library for building user interfaces that uses a virtual DOM for faster re-rendering on state changes.
- Everything in React is a component that can have states, props, and lifecycle methods like render(). Components return JSX elements.
- Props are used for passing data to components in a unidirectional flow, while states allow components to re-render on changes.
- The render() method returns the view, accessing props and state values. Forms and events also follow React conventions.

Rest Services In Mule
1) RESTful web services use HTTP methods and protocols to exchange data between applications in a standardized way. 2) In Mule, REST services can be implemented using the APIkit component, which generates APIs from RAML definitions, or the REST component, which uses JAX-RS annotations to publish services. 3) REST services in Mule can also be consumed by configuring an HTTP connector or building a custom connector using the Connector DevKit.
React js t8 - inlinecss
The document discusses two methods for adding CSS styles to React components: inline styles and external stylesheets.
For inline styles, it shows creating an object with CSS properties and applying it to a component using the style prop. For external stylesheets, it demonstrates defining CSS classes, linking a stylesheet file from index.html, and applying classes to components using the className prop.
The examples render a <Hello> component that displays an <h1> with either inline or external styles to change its color. This illustrates two common techniques for including CSS in React.
React render props
Sharing code in between react components by using render props. HOC and react prop are some of the best ways to share code in react class components.

Servlet 03
Inter-servlet communication allows servlets executing on the same server to communicate and share resources. The RequestDispatcher interface can be used to invoke one servlet from another and encapsulates the URL of a resource in a servlet context. This interface has forward() and include() methods - forward() delegates the entire request to another resource, while include() includes the output of the first servlet with the current output. The ServletContext interface provides access to data common across servlets.
Servlet
Servlets are Java classes that extend the functionality of a web server by dynamically generating web pages. Servlets use the Java programming language and are managed by a servlet container that handles loading, unloading, and directing requests. Servlets provide advantages over older technologies like CGI scripts such as better performance, portability, security, and access to full Java features. The basic servlet lifecycle involves initialization, handling requests, and destruction. Servlets can be generic or HTTP-specific, with HTTP servlets providing specialized methods for different HTTP request types. Sessions allow servlets to maintain state across multiple requests.

Servlet 03
Inter-servlet communication allows servlets executing on the same server to communicate and share resources. The RequestDispatcher interface can be used to invoke one servlet from another and encapsulates the URL of a resource in a servlet context. This interface has forward() and include() methods - forward() delegates the entire request to another resource, while include() includes the output of the first servlet with the current output. The ServletContext interface provides access to data common across servlets.
Servlet
Servlets are Java classes that extend the functionality of a web server by dynamically generating web pages. Servlets use the Java programming language and are managed by a servlet container that handles loading, unloading, and directing requests. Servlets provide advantages over older technologies like CGI scripts such as better performance, portability, security, and access to full Java features. The basic servlet lifecycle involves initialization, handling requests, and destruction. Servlets can be generic or HTTP-specific, with HTTP servlets providing specialized methods for different HTTP request types. Sessions allow servlets to maintain state across multiple requests.
Enterprise java unit-2_chapter-1
The RequestDispatcher interface provides facilities for dispatching requests between resources like servlets, JSPs, and HTML files. It has two main methods: forward() dispatches a request to another resource and the response replaces the current response, while include() dispatches a request and includes the response in the current response. For example, a servlet could validate user input, and if valid forward the request to a JSP welcome page via the RequestDispatcher, or include error messages on the same page if invalid.
Java Difference
This document provides information on the differences between various Java EE concepts:
- Forward() and sendRedirect() methods - Forward() transfers the request internally on the server side, while sendRedirect() instructs the client browser to make a new request.
- GET and POST HTTP methods - GET places parameters in the URL while POST places them in the request body. GET has limits on parameter size while POST does not.
- Include directive and include action - The directive includes content at translation time while the action includes at request time. The directive can only include static resources while the action can include dynamic content.
- Differences between concepts related to request handling in Java EE like request dispatching, session tracking, exception
J2EE Difference
This document provides information on various Java EE concepts including:
- The differences between the forward() and sendRedirect() methods, including that forward() keeps the original request object while sendRedirect() creates a new request.
- The differences between include directives and include actions in JSP, such as include directives processing at translation time while include actions process at runtime.
- The differences between GET and POST HTTP methods, including that GET requests can be cached while POST requests cannot.
- Differences between applets and servlets, with applets running on the client-side browser and servlets running on the server-side.

- Servlets handle requests and responses more efficiently than CGI due to being server-independent and allowing for session management.
- The servlet lifecycle includes initialization, request handling, and destruction. Common methods are init(), service(), doGet(), doPost(), and destroy().
- Servlets extract information from HTTP requests and use this to generate and return HTTP responses by setting headers and writing response content.
E-MARKETING E-ZONE PPT Using ADVANCED JAVA
Online shopping (sometimes known as e-tail from "electronic retail" or e-shopping) is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser. Alternative names are: e-web-store, e-shop, e-store, Internet shop, web-shop, web-store, online store, online storefront and virtual store. Mobile commerce (or m-commerce) describes purchasing from an online retailer's mobile optimized online site or app.
Servlets
Servlets are Java programs that run on the server-side and dynamically generate web pages using Java code. Servlets provide server-side programming functionality and are an effective replacement for CGI scripts. Servlets follow a standard API and can be deployed across distributed server environments.
Java Servlets
The document discusses the core concepts of Java web technology including servlet containers, types of servlet containers, the javax.servlet package, the servlet lifecycle, servlet configuration using ServletConfig, sharing data using ServletContext, and request dispatching using RequestDispatcher. A servlet container runs servlets and acts as the interface between the web server and servlets. Servlets are loaded, initialized, service requests, and destroyed according to their lifecycle managed by the servlet container.

Java servlets
This document provides an overview of Java servlets, including:
- Servlets reside on the server-side and generate dynamic web pages. They handle HTTP requests and responses.
- Servlets have a lifecycle of initialization, processing requests, and destruction. The servlet receives a request from the web server, processes it, and returns a response which is sent back to the client.
- Servlets offer advantages over CGI like better performance through multithreading and portability through the Java programming language. Common servlet APIs and interfaces are described.
Java servlets
This document provides an overview of Java servlets. It discusses that servlets are modules that extend request/response-oriented servers like Java web servers. Unlike applets, servlets do not have a graphical user interface. The document then covers servlet basics, uses for servlets including providing CGI script functionality and load balancing, and differences between generic and HTTP servlets. It also provides examples of simple servlets and using HTTP servlets to process web forms and handle GET and POST requests. Finally, it discusses session state maintenance using HTTP session objects.
Basics Of Servlet
Servlet is just a java program which is present on server side.
It helps to handle dynamic request from web server.
Introduction to Ajax programming
The document discusses client-side web development technologies including Rich Internet Applications (RIAs) and AJAX. RIAs are web apps that have features of desktop apps, processing mainly on the client-side while keeping data on servers. AJAX allows asynchronous JavaScript requests to servers without page reloads, improving responsiveness. It uses the XMLHttpRequest object to transfer data from servers in the background.
Request dispacther interface ppt
The RequestDispatcher interface in Java allows servlets to dispatch or forward requests to other resources on the server like HTML files, JSP pages, or other servlets. It provides two main methods - forward() to forward a request and include() to include the response of a resource in the current response. The getRequestDispatcher() method of the ServletRequest interface returns a RequestDispatcher object that can then be used to call the forward() or include() methods, passing the request and response objects. An example is provided of a login servlet that uses RequestDispatcher to forward successfully authenticated requests to a welcome servlet or include an error message on failed authentication.

2. Key aspects of servlet architecture like the servlet lifecycle, the HttpServletRequest and HttpServletResponse objects, and how different HTTP methods map to servlet methods.
3. Examples of simple servlets that process parameters, maintain a session counter, and examples of deploying servlets in Eclipse IDE.
JSP- JAVA SERVER PAGES
This document provides an overview of Java Server Pages (JSP) technology. It discusses how JSP pages combine HTML/XML markup with Java code to create dynamic web content. Key points include:
- JSP pages are converted into Java servlets by the JSP container/engine to generate HTML responses. This allows accessing Java APIs and databases.
- Common JSP elements like scriptlets, expressions, declarations, comments, and directives allow embedding Java code in JSP pages.
- The JSP lifecycle mirrors the servlet lifecycle with phases like initialization, execution, and destruction.
- Standard Tag Libraries (JSTL) provide commonly used tags to simplify tasks like iteration, conditionals,

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Servlet session 8
- 1. SESSION – 8 By→ Anuj Kumar Singh
- 2. SendRedirect in Servlet The sendRedirect() method of HttpServletResponse interface can be used to redirect response to another resource, it may be servlet, jsp or html file. It accepts relative as well as absolute URL. It works at client side because it uses the url bar of the browser to make another request.
- 3. Difference between forward() and SendRedirect() method forward() SendRedirect() The forward() method works at server side. The SendRedirect() method works on client Side. It sends the same request and response objects to another servlet. It always sends new request. It works within the server only. It can be used within and outside the server. Example : request.getRequestDispatcher(“Servlet2”); foward(request,response); Example: response.sendRedirect(“servlet2”);
- 7. ServletConfig Interface 1. An object of ServletConfig is created by web container for each servlet. This object can be used to get configuration information from web.xml file. 2. If the configuration information is modified in the web.xml file, we don't need to change the servlet. So it is easier to manage the web application if any specific content is modified from time to time. Advantages of ServletConfiguration The core advantage of ServletConfig is that you don't need to edit the servlet file if information is modified from the web.xml file.
- 8. Methods of ServletConfig interface 1. public String getInitParameter(String name):Returns the parameter value for the specified parameter name. 2. public Enumeration getInitParameterNames():Returns an enumeration of all the initialization parameter names. 3. public String getServletName():Returns the name of the servlet. 4. public ServletContext getServletContext():Returns an object of ServletContext
- 9. How to get the object ServletConfig 1. getServletConfig() method of Servlet interface returns the object of ServletConfig. public ServletConfig getServletConfig(); 2. Example of getServletConfig() method ServletConfig config=getServletConfig(); //Now we can call the methods of ServletConfig interface String driver =config.getInitParameter(“driver”); 3. Code in web.xml file <init-param> <param-name>driver</param-name> <param-value>com.mysql.jdbc.Driver</param-value> </init-param>
