J2EE (Java 2 Platform, Enterprise Edition) is a platform for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications. It uses a distributed multi-tiered application model where application logic is divided into components running on different machines depending on their function. Components include web components, enterprise beans running business logic on the server, and application clients running on the client. The J2EE platform provides containers that manage these components and offer underlying services like transaction management, security, and connectivity.
The document provides an introduction to the Struts framework. It describes Struts as an open source MVC framework that implements the JSP Model 2 architecture. It stores routing information in a configuration file and separates the model, view, and controller layers. All requests are routed through the Struts controller which uses the configuration file to map requests to actions, which then call services and forward to view resources.
The document discusses the evolution of distributed computing and challenges in developing enterprise applications across multiple machines, noting how Java 2 Enterprise Edition (J2EE) platform addresses these issues through its support for multi-tier architectures. It describes the J2EE architecture and programming model which promotes component-oriented code reuse, leverages inter-tier communication, and focuses on integration across tiers through technologies like Java servlets, JavaServer Pages, Enterprise JavaBeans and more. Key aspects of the model-view-controller (MVC) architecture are also outlined.

- Java 2 Platform, Enterprise Edition (J2EE) builds upon Java 2 Platform, Standard Edition (J2SE) and is used to create large, distributed, multi-tier enterprise applications. It provides APIs and services for these types of applications.
- J2EE applications typically use a multi-tier architecture with client, web, business, and data tiers. The client tier interacts with users/devices. The web tier contains web components like servlets and JSPs. The business tier houses enterprise beans that implement business logic. The data tier consists of databases.
- Containers in each tier manage components and provide common services. For example, the EJB container manages enterprise beans and provides transactions.
Web programming and development - IntroductionJoel Briza
The document provides an overview of key concepts in web programming and Java Enterprise Edition (Java EE), including:
1) Java EE aims to provide developers with APIs to shorten development time and improve application performance. It is developed through the Java Community Process.
2) Java EE applications use a multitier architecture with client, web, business, and backend tiers. Components include web components, enterprise beans, and application clients.
3) Java EE containers manage the execution of components and include application servers, web containers, EJB containers, and application client containers.
The document discusses the implementation of a project, including:
- The selection of Windows 7 and a platform-independent J2EE platform for development
- The selection of Java as the programming language due to its object-oriented capabilities, rich APIs, powerful development tools, open source libraries, and platform independence
- The use of Oracle Database for its reliability and ability to ensure data integrity through ACID properties
- Requirements including Java/J2EE, HTML, JavaScript, JSON, and Tomcat as the web server
- Guidelines for programming including naming conventions and handling exceptions
- The implementation procedure including creating a dynamic web project in Eclipse and exporting a WAR file
The document provides an introduction to Java Enterprise Edition (Java EE) including:
1. An overview of what Java EE is, its key deliverables and basic multi-tier architecture with components and containers.
2. The benefits of Java EE for developers, vendors and businesses including application portability and large developer community support.
3. A brief description of the most common Java EE technologies, specifications, APIs and how applications are assembled and deployed on Java EE platforms.
The document provides an overview of the Model-View-Controller (MVC) design pattern, including its context, problem, and solution. It then discusses how MVC is used in the Java Pet Store example application to separate the application logic and data (Model) from the user interface (View) and control logic (Controller). Key aspects of MVC like separation of concerns and allowing multiple Views of the same data are highlighted.
Application servers help with application integration by providing middleware functionality like transactions, security, and persistence. They provide an environment for hosting application logic and can be used for both enterprise application integration and web-based integration. The two dominant application server platforms are J2EE and .NET. J2EE's main components include support for the application layer through EJBs, JNDI, and JMS, and support for connecting to resource managers through JDBC and J2CA.
The document discusses the roles involved in developing, assembling, and deploying Java EE applications. It describes the Java EE product provider who implements the Java EE platform, the tool provider who develops tools, the application component provider who creates reusable Java EE components packaged in JAR/WAR files, and the application assembler who bundles these components into an EAR file. Finally, an application deployer installs the EAR file onto a Java EE server.
The document provides an overview of the Java EE 7 platform. It describes Java EE 7 as an enterprise application platform that aims to simplify development by providing common foundations and APIs. The key components of Java EE 7 applications include web components, enterprise beans, application clients, and Java EE containers that manage the execution of components. The document also outlines the architecture of Java EE applications and how different application parts interact, as well as APIs, tools, and benefits of the Java EE 7 platform for developers.

This document provides an overview of enterprise application development using Java. It discusses the evolution from two-tier client-server architectures to the more scalable multi-tier Java 2 Platform, Enterprise Edition (J2EE). Key components of J2EE include servlets, JavaServer Pages (JSP), and Enterprise JavaBeans (EJB) that allow developing scalable applications across tiers for clients, presentation logic, and application logic. EJBs in particular help encapsulate complex business logic and coordinate transactional work across entity beans. The document outlines the benefits of J2EE like component-based models, container services, and simplified yet flexible architectures for developing enterprise applications using Java.
This document provides a high-level overview of the design and functional specifications for a STEM (Science, Technology, Engineering, and Math) web application. It describes the application's logical architecture with separate layers for the presentation layer, controller, model, and data layers. It also outlines the key technologies used including ASP.NET, C#, and SQL Server. The document discusses the MVC framework that will be used and defines the roles of controllers and actions. It provides a high-level view of the application components in each layer and describes the user interface elements and processes.
This document discusses J2EE (Java 2 Platform, Enterprise Edition), which is a Java platform for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications. It provides an architecture that simplifies development and maintenance of enterprise applications. Some key points made are:
- J2EE aims to reduce server downtime, increase scalability, provide application stability, security and simplicity.
- It allows "develop once, deploy anywhere" capability and supports n-tier architectures and component-based development.
- J2EE applications are best suited for tasks like providing access to corporate databases, building dynamic web apps, automating communications, and implementing complex business logic.
- Java EE provides APIs to develop distributed applications using the client-server model, where requests from clients are served by remote servers.
- In the client-server model, a client such as a web browser makes requests to a server like a web server, which responds with static or dynamic content typically in HTML format.
- The Java EE platform facilitates an architecture where business components are placed in a separate middle tier, enhancing features like scalability, extensibility and maintainability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

7. Single-Tier: Pros & Cons ? Pros: – No client side management is required – Data consistency is easy to achieve ? Cons: – Functionality ( presentation, data model, business logic intertwined), makes difficult for updates and maintenance and code reuse
10. Two-Tier: Pros & Cons ? Pro:– DB product independence (compared to single-tier model) ? Cons: business logic and data access logic are intertwined (at client side), difficult for updates and maintenance – Data Model is “tightly coupled” to every client: If DB Schema changes, all clients break – Updates have to be deployed to all clients making System maintenance nightmare – DB connection for every client, thus difficult to scale Raw data transferred to client for processing causes high network traffic

Enterprise beans and their container run on the J2EE server. Web container Manages the execution of JSP page and servlet components for J2EE applications. Web components and their container run on the J2EE server. Application client container Manages the execution of application client components. Application clients and their container run on the client. Applet container Manages the execution of applets. Consists of a web browser and Java Plug-in running on the client together J2EE server archi
26. J2EE Connector Architecture The J2EE Connector architecture is used by J2EE tools vendors and system integrators to create resource adapters that support access to enterprise information systems that can be plugged in to any J2EE product. A resource adapter is a software component that allows J2EE application components to access and interact with the underlying resource manager of the EIS. Because a resource adapter is specific to its resource manager, typically there is a different resource adapter for each type of database or enterprise information system. The J2EE Connector architecture also provides a performance-oriented, secure, scalable, and message-based transactional integration of J2EE-based web services with existing EISs that can be either synchronous or asynchronous. Existing applications and EISs integrated through the J2EE Connector architecture into the J2EE platform can be exposed as XML-based web services by using JAX-RPC and J2EE component models. Thus JAX-RPC and the J2EE Connector architecture are complementary technologies for enterprise application integration (EAI) and end-to-end business integration. j2ee
27. JAAS The Java Authentication and Authorization Service (JAAS) provides a way for a J2EE application to authenticate and authorize a specific user or group of users to run it. JAAS is a Java programing language version of the standard Pluggable Authentication Module (PAM) framework, which extends the Java 2 Platform security architecture to support user-based authorization .
28. Java Naming and Directory Interface The Java Naming and Directory Interface (JNDI) provides naming and directory functionality. It provides applications with methods for performing standard directory operations, such as associating attributes with objects and searching for objects using their attributes. Using JNDI, a J2EE application can store and retrieve any type of named Java object. J2EE naming services provide application clients, enterprise beans, and web components with access to a JNDI naming environment. A naming environment allows a component to be customized without the need to access or change the component's source code. A container implements the component's environment and provides it to the component as a JNDI naming context . A J2EE component locates its environment naming context using JNDI interfaces. A component creates a javax.naming.InitialContext object and looks up the environment naming context in InitialContext under the name java:comp/env . A component's naming environment is stored directly in the environment naming context or in any of its direct or indirect subcontexts. A J2EE component can access named system-provided and user-defined objects. The names of system-provided objects, such as JTA UserTransaction objects, are stored in the environment naming context, java:comp/en v. The J2EE platform allows a component to name user-defined objects, such as enterprise beans, environment entries, JDBC DataSource objects, and message connections. An object should be named within a subcontext of the naming environment according to the type of the object. For example, enterprise beans are named within the subcontext java:comp/env/ejb , and JDBC DataSource references in the subcontext java:comp/env/jdbc . Because JNDI is independent of any specific implementation, applications can use JNDI to access multiple naming and directory services, including existing naming and directory services such as LDAP, NDS, DNS, and NIS. This allows J2EE applications to coexist with legacy applications and systems. For more information on JNDI, see The JNDI Tutorial :
29. Java Transaction API The Java Transaction API (JTA) provides a standard interface for demarcating transactions. If your application performs two separate database access operations that depend on each other, you will want to use the JTA API to demarcate where the entire transaction, including both operations, begins, rolls back, and commits
30. JDBC API The JDBC API lets you invoke SQL commands from Java programming language methods. You use the JDBC API in an enterprise bean when you override the default container-managed persistence or have a session bean access the database. With container-managed persistence, database access operations are handled by the container, and your enterprise bean implementation contains no JDBC code or SQL commands. You can also use the JDBC API from a servlet or a JSP page to access the database directly without going through an enterprise bean. The JDBC API has two parts: an application-level interface used by the application components to access a database, and a service provider interface to attach a JDBC driver to the J2EE platform
31. Java API for XML Processing JAXP The Java API for XML Processing (JAXP) supports the processing of XML documents using Document Object Model (DOM), Simple API for XML (SAX), and Extensible Stylesheet Language Transformations (XSLT). JAXP enables applications to parse and transform XML documents independent of a particular XML processing implementation. JAXP also provides namespace support, which lets you work with schemas that might otherwise have naming conflicts. Designed to be flexible, JAXP lets you use any XML-compliant parser or XSL processor from within your application and supports the W3C schema. You can find information on the W3C schema at this
32. JAF The JavaBeans Activation Framework (JAF) is included because JavaMail uses it. JAF provides standard services to determine the type of an arbitrary piece of data, encapsulate access to it, discover the operations available on it, and create the appropriate JavaBeans component to perform those operations
33.
34.
35. Java API for XML-Based RPC The Java API for XML-based RPC (JAX-RPC) uses the SOAP standard and HTTP, so client programs can make XML-based remote procedure calls (RPCs) over the Internet. JAX-RPC also supports WSDL, so you can import and export WSDL documents. With JAX-RPC and a WSDL, you can easily interoperate with clients and services running on Java-based or non-Java-based platforms such as .NET. For example, based on the WSDL document, a Visual Basic .NET client can be configured to use a web service implemented in Java technology, or a web service can be configured to recognize a Visual Basic .NET client. JAX-RPC relies on the HTTP transport protocol. Taking that a step further, JAX-RPC lets you create service applications that combine HTTP with a Java technology version of the Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols to establish basic or mutual authentication. SSL and TLS ensure message integrity by providing data encryption with client and server authentication capabilities. Authentication is a measured way to verify whether a party is eligible and able to access certain information as a way to protect against the fraudulent use of a system or the fraudulent transmission of information. Information transported across the Internet is especially vulnerable to being intercepted and misused, so it's very important to configure a JAX-RPC web service to protect data in transit.
38. JSP->Bean->EJB EJB -> Bean -> JSP JavaBeans component manage the user input and send that input to enterprise beans running in the business tier for processing.
43. EJB CONSTITUENTS There are three kinds of enterprise beans: session beans, entity beans , and message-driven beans . A session bean represents a transient conversation with a client. When the client finishes executing, the session bean and its data are gone. In contrast, an entity bean represents persistent data stored in one row of a database table. If the client terminates or if the server shuts down, the underlying services ensure that the entity bean data is saved. A message-driven bean combines features of a session bean and a Java Message Service (JMS) message listener, allowing a business component to receive JMS messages asynchronously
44. EJB Customer Bean Order Bean Shopping cart Bean Application A Customer Bean Order Bean Shopping cart Bean Inventory Bean Bean Application B Written by X Written by Y Enterprise beans are building blocks that can be used alone or with other enterprise beans to execute business logic on the J2EE server.
46. What Is the J2EE? Open standard based platform for developing, deploying and managing n-tier, Web-enabled, server-centric, and component-based enterprise platform J2EE, In short, is an open standard, development and deployment platform for building n-tier, web-based and server-centric, and component-based enterprise applications.
47. Evolution of Enterprise Application Framework ? Single tier ? Two tier ? Three tier ? Four tier (HTML browser and Web server ) For Distributed point to point communication two technologies are involved – RPC based – Remote object based
49. Three-tier (RPC based): Pros & Cons Pro:– Business logic can change more flexibly than 2- tier model ? Most business logic reside in the middle-tier server ?Cons:– Complexity is introduced in the middle-tier server – Client and middle-tier server is more tightly coupled (than the three-tier object based model) – Code is not really reusable (compared to object model based)
53. Three-tier (Remote Object based): Pros & Cons ? Pro: – More loosely coupled than RPC model – Code could be more reusable ? Cons: – Complexity in the middle-tier still need to be addressed
54. Java Message Service API The Java Message Service (JMS) API is a messaging standard that allows J2EE application components to create, send, receive, and read messages. It enables distributed communication that is loosely coupled, reliable, and asynchronous
56. Three-tier (Web Server based):Pros & Cons ? Pro: – Ubiquitous client types – Zero client management – Support various client devices ? J2ME-enabled cell-phones ? Cons: – Complexity in the middle-tier still need to be addressed Trends ? Moving from single-tier or two-tier to multitier architecture ? Moving from monolithic model to objectbased application model ? Moving from application-based client to HTML-based client So based on this evolution, we can observe a few trends. First, moving from a single tier or two-tier model to multi-tier model. Second, moving from the monolithic code to object-based application model. Lastly, HTML browser based clients are taking some strong hold. 03/19/2007
57. Web Server based:Pros & Cons Trends ? Moving from single-tier or two-tier to multitier architecture ? Moving from monolithic to objectbased application model ? Moving from application-based client to HTML-based client

66. Java Mail API J2EE applications use the JavaMail API to send email notifications. The JavaMail API has two parts: an application-level interface used by the application components to send mail, and a service provider interface. The J2EE platform includes JavaMail with a service provider that allows application components to send Internet mail

74. Web Tier and J2EE Applications the web tier includes JavaBeans components to manage the user input and send that input to enterprise beans running in the business tier for processing.
75. Business and EIS Tiers Enterprise bean receives data from client programs, processes it (if necessary), and sends it to the enterprise information system tier for storage. An enterprise bean also retrieves data from storage, processes it (if necessary), and sends it back to the client program
76. VARIOUS APIS IN J2EE Java Mail : AP enables Java Mail programmers / Clients to communicate by sending e-mail message use order confirmation. JMS : Java Message Service allows components to send and release asynchronous messages provides their own API for messages. API is used to build into Java Programmes a trans message link between components. JAXP : API supports passing of XML documents using DOM (Document Object Model). A simple API for XML style sheet language for transformation (XSLT). JAAS : API provides security (Java Authentication and Authentication) Imposes authentication and authorization checks on users. JNDI : API provides directory service by which J2EE components can be requested and discovered. Objects can be locates in various on servers. API provides standout namely conventions so that programmers can look up objects from Java programs. JDBC : API enables programmes to connect to and interact when practically all databases.
