Enterprise Java Beans (EJBs) allow developers to create reusable components (beans) that can be assembled into applications. EJBs provide services like transactions and security so developers can focus on business logic. Beans run under an EJB container that handles method calls and inserts services. There are three types of beans: entity beans represent database rows, session beans represent processes, and message-driven beans consume JMS messages. Session beans can be stateless, with one bean handling multiple clients concurrently without state, or stateful, where each client is assigned its own bean that maintains state.

Enterprise java beans(ejb) update 2
Enterprise Java Beans (EJBs) allow developers to create reusable components called beans that can be assembled into applications. A bean represents some business logic or functionality that can be reused across applications, such as a customer bean that represents a customer in a database. EJBs take code reuse to a new level by allowing whole functionalities to be reused rather than just code. EJBs let developers focus on business logic while the underlying services like transactions and security are handled by the EJB server.
Enterprise java beans(ejb)
Enterprise Java Beans (EJBs) allow developers to create reusable components called beans that can be assembled into applications. A bean represents some business logic or functionality that can then be used across different programs. EJBs handle transactions, security, and other services for beans so developers can focus on business logic. Beans run under an EJB container that manages method calls and inserts services like transactions. There are three types of beans: entity beans that represent database rows, message-driven beans that consume JMS messages, and session beans for other business processes.

Enterprise JavaBeans(EJB)
1) Enterprise JavaBeans (EJBs) are server-side components that expose methods for performing application logic. There are two main types: session beans and message-driven beans.
2) Session beans represent actions or a session and can be either stateless or stateful. Stateless session beans handle a single request and do not maintain conversational state, while stateful session beans span multiple requests and retain state for an individual client.
3) The document provides an example of a bank account application using EJBs, and describes the components of an EJB including business interfaces, EJB classes, and packaging into an EJB JAR file.
Jsp
The key differences between variables declared in a JSP declaration part versus a scriptlet are:
- Variables declared in a declaration part are instance variables of the generated servlet class, while variables declared in a scriptlet are local to the _jspService() method.
- Declaration part variables have broader scope across the entire JSP and servlet, while scriptlet variables are only accessible within the scriptlet.
JSPExecutor is a tool that allows executing JSP files from the command line or own applications, bypassing the servlet container. It is useful for code generation but lacks full servlet functionality.
EJB Part-1
This document provides an overview of Remote Method Invocation (RMI) and steps for developing RMI applications in Java. RMI allows a program on one machine to invoke methods on Java objects residing in another JVM. It uses stub and skeleton classes to enable remote communication between objects. The summary describes developing an RMI application which includes defining an interface, creating an implementation class, binding the object in the registry, and looking it up from the client.
Enterprise Java Beans - EJB
Overview of EJB technology.
Enterprise Java Beans (EJB) is a server-side component technology for Java EE based systems (JEE).
Beans are business logic components that implement a standard interface through which the bean is hooked into the bean container (= runtime object for bean).
A Java class implementing one of the standard bean interfaces is an Enterprise Java Bean. Beans can be accessed remotely, usually from a client tier.
The EJB standard was developed to provide a common framework for solving recurring problems in business application development like persistence, transactions,
security and runtime and lifecycle management. The EJB standard evolved greatly over time. EJB version 1 and 2 were complex and required to implement many interfaces
and exception handling in EJBs. EJB version 3 brought great simplifications and did away with interfaces by replacing these with annotations which provide greater flexibility while keeping complexity low. EJBs come in 3 different flavors: Stateless and stateful session beans and message driven beans. Entity beans of EJB version 1 and 2 were replaced by the Java Persistence API in EJB version 3.
Spring IOC and DAO
The document discusses Spring IOC and DAO. It provides an overview of Spring framework, Inversion of Control (IOC) and Dependency Injection in Spring. It also describes how Spring supports data access with JDBC Template and DAO implementations. The JDBC Template simplifies JDBC usage and avoids common errors by providing callback interfaces for writing and reading database operations. Spring DAO classes can extend support classes to get a JDBC or Hibernate template based on the persistence mechanism.

Session 3 Tp3
The key components of an enterprise bean include the bean class, EJB object, home interface, home object, and deployment descriptors. A stateless session bean handles business logic without retaining data between method calls. The EJB container manages transactions, security, and instances to provide services to the bean. Clients access beans through JNDI lookup of the home object which creates EJB objects that delegate method calls to the bean class. Deployment requires packaging the bean class, interfaces, and descriptors into an ejb-jar file.
Ejb intro
Enterprise JavaBeans (EJBs) are reusable software components that can represent either data (entity beans) or business logic (session beans). EJBs provide benefits like transaction management, security, and the ability to be deployed on application servers. There are different types of session beans, including stateful and stateless, and entity beans can use either bean-managed or container-managed persistence to access a database. To use an EJB, a client first locates its home interface using JNDI and then calls methods on the home interface to access the bean.

Ejb intro
Enterprise JavaBeans (EJBs) are reusable software components that can represent either business logic or data. There are two main types of EJBs - session beans which represent business logic and entity beans which represent and manipulate data. EJBs provide benefits like transaction management, security, and abstraction from technical details. They allow components to be reused across applications and systems. EJBs communicate using RMI over IIOP and can be accessed from various clients including other EJBs, servlets, JSPs and applications in any language that supports CORBA.

Agile
The document discusses agile methodology and its core principles. It defines agile as an incremental, iterative approach that values frequent delivery of working software and responsiveness to change. The document outlines traditional software development models like waterfall and spiral, then introduces the agile manifesto and its emphasis on individuals, collaboration, customer feedback and responding to change. It describes various agile roles, practices like scrum and XP, and the overall process of organizing work into short iterations to deliver working software.
Web tech importants
The document provides study recommendations for an exam, listing key topics to focus on for chapters about XML (DTD, XML Schema, DOM, SAX), servlet lifecycle, JSP elements (directives, scripting elements, action tags), and JDBC. Links are included to slideshare presentations covering each topic. The recipient is asked to forward the information to classmates and wished good luck on the exam.
2 4 Tree
1. A (2,4)-tree is a type of multiway search tree where each node has between 2 and 4 children and all external nodes are at the same depth, maintaining the tree's balanced structure.
2. Insertion of a new key into a (2,4)-tree is done through searching, then inserting the key and splitting overflowed nodes, maintaining the structure properties. Deletion is done by searching, then deleting and fusing or transferring nodes to resolve underflows.
3. Both insertion and deletion take O(logn) time through splitting or fusing a constant number of nodes per operation while searching takes O(logn) time, maintaining the optimal O(logn
23 Tree Best Part
The document summarizes 2-3 trees, which are binary search trees where each internal node has either 2 or 3 children. It describes the structure of internal and leaf nodes, and provides algorithms for searching, inserting, and deleting elements in 2-3 trees. Searching follows the structure of the tree to guide the search path. Insertion may split nodes or increase the tree height, while deletion may merge nodes or decrease the height.
JSP Scope variable And Data Sharing
The document discusses the different scopes that can be used to store objects and data in JSP and servlet applications - page, request, session, and application. Objects stored in different scopes are accessible from different parts of the application. Data can be stored in these scopes using attributes, which are key-value pairs. The document provides examples of how to store and retrieve attributes using these different scopes in both JSP pages and servlets.
Bean Intro
Java Beans are reusable software components that can be visually manipulated in builder tools. They allow developers to write reusable components once and run them anywhere on any Java-enabled platform. Key features of Java Beans include properties, events, persistence, and introspection to allow visual manipulation in builder tools. Customization is also supported to allow customizing a bean's appearance and behavior.
jdbc
JDBC is a standard API for accessing SQL databases from Java programs. There are four types of JDBC drivers: Type 1 uses JDBC/ODBC bridge, Type 2 uses platform-specific APIs, Type 3 is 100% Java using network protocol, and Type 4 is also 100% Java and most efficient. Connector/J is a popular Type 4 driver for connecting Java to MySQL. To connect, import necessary classes, register the driver, get a connection, then create statements to execute queries or updates.
Sax Dom Tutorial
This document provides an overview of DOM and SAX, two common XML APIs in Java. It describes the key differences between DOM and SAX, including that DOM builds an in-memory tree representation, while SAX parses the XML as a stream of events. The document also provides code examples for using SAX to parse XML and extract data, and examples of how to access and manipulate DOM trees after parsing XML.
Xml
XML documents must follow certain formatting rules to be considered well-formed. They must have a single root element with matching start and end tags for all other elements. Attribute values must be enclosed in quotes. Well-formed XML documents can be represented as a tree structure with a root node containing child nodes, some of which may themselves contain child nodes. The fundamental unit of XML is the element, which can have attributes and content.
Dtd
The document discusses the building blocks of XML documents including elements, attributes, entities, PCDATA, and CDATA. It also covers how each component is declared in a DTD including element declarations, attribute declarations, and restrictions on content and occurrence.
Xml Schema
An XML schema defines the structure and elements of an XML document. It is an XML-based alternative to DTDs that allows defining element types, attributes, data types, defaults and restrictions. Schemas support namespaces, data types, extensibility and are written in XML, allowing the use of XML tools. Complex elements can contain child elements, text or both.
JSP
Java Server Pages (JSP) is a technology that allows developers to create dynamic web applications using Java code embedded in HTML pages. JSP pages are compiled into Java servlets, allowing dynamic content to be generated. JSP supports the use of scripting elements like expressions, scriptlets, and declarations directly in HTML pages to add dynamic functionality. Common elements like directives, actions, and standard tags provide functionality like including pages, passing parameters, and abstracting common patterns.
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.
Servlet Part 2
The document discusses the key differences between ServletConfig and ServletContext in Java servlets. ServletConfig contains information for a single servlet and is used to access initialization parameters and the ServletContext. ServletContext contains information about the entire web application and can be used to store attributes accessible by all servlets. The document also provides an overview of the HttpServletRequest and HttpServletResponse objects, describing common methods for handling requests and responses. It explains how to define initialization parameters for servlets and contexts in the deployment descriptor and access them programmatically.
Tutorial Solution
HTTP is the protocol used to deliver web pages and other resources over the internet. It uses a client-server model, where an HTTP client like a web browser sends requests to an HTTP server, which responds with the requested resources. Requests and responses consist of request/response lines followed by headers and an optional message body. Common request methods are GET and POST, while common response status codes include 200 for success and 404 for "not found". Web servers listen on port 80 by default to receive HTTP requests and send responses. Servlets are Java programs that extend the capabilities of web servers by allowing applications to be executed on the server-side. Servlets provide advantages over CGI scripts like improved performance through caching and platform independence through their Java
Java Script Language Tutorial
The document summarizes key elements of JavaScript grammar including variables, operators, expressions, statements, objects, functions, and methods. It provides examples and definitions of each element and notes that JavaScript code uses these elements to make assignments, compare values, and execute sections of code.
Web Tech Java Servlet Update1
The document provides an introduction to Java web technology and servlets. It discusses HTTP and its request/response model. It describes common HTTP methods like GET and POST, and explains the difference between the two. It also covers the servlet lifecycle, web containers, and setting up a servlet development environment.
Sample Report Format
This document outlines the requirements and design of a minor project for a Bachelor of Engineering degree. It describes the objectives of developing a mobile application to provide internet access. It provides details on the project overview, requirements analysis, application design, implementation, testing, and future work. Appendices include references, project outputs, and code listings. The document follows formatting guidelines for the report.
Javascript
JavaScript is a dynamic programming language originally designed for web browsers but now used in many non-browser environments. It was misunderstood early on due to its name association with Java, inconsistent implementations across browsers, and loose typing. Key features include load-and-go delivery, loose typing where values can be treated as different types, objects used as general containers, prototypal inheritance, and functions as first-class objects. All values in JavaScript are either primitive values (strings, numbers, booleans, null, undefined) or objects.
Javascript
The JavaScript Programming Language document provides an overview of the JavaScript programming language, including its history, key concepts, values, operators, statements, and objects. It notes that JavaScript is a multi-paradigm scripting language that is misunderstood as only for web development. The document outlines JavaScript's core data types, objects, functions, and prototypal inheritance model.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Enterprise java beans(ejb) Update 2
- 1. Enterprise Java Beans(EJB) With EJBs, you can develop building blocks ‘ejb components ’ – that u and someone else can assemble and reassemble into different applications. For example , you might create a customer bean that represents a customer in database. You can use that Customer bean in an accouting program, an e-commerce shopping cart and a tech support application. One beauty of EJBs is that you take code reuse to a whole new level, instead of just code it reuses whole functionality and allows you modify that way bean behaves at runtime with touching its java code. 06/25/10 JavaTruths.com:A Portal for all java related stuff!!!
