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.
RESTEasy is a framework for building RESTful web services in Java. It allows developers to write JAX-RS annotated Java classes to define resources and their representations. Resources are addressable via URIs and support standard HTTP methods like GET, PUT, POST, and DELETE. Resources return representations in formats like JSON, XML, and HTML. Communication is stateless and driven by hypermedia links between resources. RESTEasy supports features like interceptors, asynchronous jobs, caching, GZIP compression, and integration with Spring and other frameworks.
Spring Boot is a framework for creating stand-alone, production-grade Spring-based applications that can be started using java -jar without requiring any traditional application servers. It is designed to get developers up and running as quickly as possible with minimal configuration. Some key features of Spring Boot include automatic configuration, starter dependencies to simplify dependency management, embedded HTTP servers, security, metrics, health checks and externalized configuration. The document then provides examples of building a basic RESTful web service with Spring Boot using common HTTP methods like GET, POST, PUT, DELETE and handling requests and responses.
The document discusses the Generic Connection Framework (GCF) in Java, which provides an extensible framework for I/O and networking. It describes the connection hierarchy in GCF, including interfaces like Connection, InputConnection, and HttpConnection. It also covers how to create and use HTTP connections to make client requests and process server responses in Java, including using GET and POST methods. Specific examples are given around retrieving data from a servlet and database using GET and POST.
The document discusses extending service-oriented architecture (SOA) with REST and Web 2.0 principles. It defines representational state transfer (REST) and describes its characteristics, including being resource-centric, using uniform interfaces, and being stateless. It advocates designing SOAs in a RESTful way by following best practices like using standard HTTP methods and URIs to access resources.
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.

The document discusses developing RESTful web services using JAX-RS. It describes how JAX-RS allows identifying resources with URIs, communicating with standard HTTP methods, supporting multiple representations through content negotiation, and linking resources together through embedded URIs. Resources are represented as Java POJO classes annotated with JAX-RS annotations.
JDBC (Java Database Connectivity) provides a standard interface for connecting Java applications to different database systems. There are four main types of JDBC drivers:
1. JDBC-ODBC bridge driver - Used to connect to any ODBC compliant database. It is platform dependent.
2. Native-API (partially Java) driver - Uses a database vendor's native API. Faster than JDBC-ODBC but still platform dependent.
3. Network protocol driver - Uses a database-independent protocol like ODBC or SQL/CLI. Platform independent but not as fast as native.
4. Pure Java driver - Written entirely in Java. Fastest,
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.
This document discusses REST (REpresentational State Transfer) and how to implement RESTful services on Android. It begins by defining REST and describing its core concepts like client-server architecture, statelessness, uniform interface, and CRUD (create, read, update, delete) operations.

This document discusses Fork/Join framework in Java 7. It explains that Fork/Join is designed to maximize usage of multiple processors by recursively splitting large tasks into smaller subtasks. It uses work-stealing algorithm where idle workers can steal tasks from busy workers' queues to balance load. An example of calculating Fibonacci numbers using Fork/Join is provided where the task is split recursively until the subproblem size is smaller than threshold, at which point it is computed directly.
This document compares different methods for measuring performance and timing logic in Java, including System.currentTimeMillis(), System.nanoTime(), the StopWatch class from Apache Commons Lang, and the StopWatch utility from Spring Core. Code examples are provided for each method to demonstrate how to use it and sample output is shown. The Spring and Commons StopWatch implementations are then compared in terms of functionality.

BT & Neo4j: Knowledge Graphs for Critical Enterprise Systems.pptx.pdfNeo4j
Presented at Gartner Data & Analytics, London Maty 2024. BT Group has used the Neo4j Graph Database to enable impressive digital transformation programs over the last 6 years. By re-imagining their operational support systems to adopt self-serve and data lead principles they have substantially reduced the number of applications and complexity of their operations. The result has been a substantial reduction in risk and costs while improving time to value, innovation, and process automation. Join this session to hear their story, the lessons they learned along the way and how their future innovation plans include the exploration of uses of EKG + Generative AI.
Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

Fluttercon 2024: Showing that you care about security - OpenSSF Scorecards fo...Chris Swan
Have you noticed the OpenSSF Scorecard badges on the official Dart and Flutter repos? It's Google's way of showing that they care about security. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge.
You can do the same for your projects, and this presentation will show you how, with an emphasis on the unique challenges that come up when working with Dart and Flutter.
The session will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across an organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.

Spring MVC 3 Restful
1. Spring 3 MVC Rest (3.0.5 기준)김용환Knight76 at gmail.comKnight76.tistory.com맛보기
2. 특징REST를 쓰기 위해서 Spring MVC 모델을 그대로 차용, Annotation 이용(Controller)JSR 311을 따르지는 않지만, 대부분의 기능 구현하나의 리소스는 여러 개의 Represenation을 가질 수있도록함 (JSON/XML/ATOM/RSS)브라우저에서 지원하지 않는 PUT & POST 요청을 처리할 수 있음Custom parser 이용 가능UTIL(converter..) 클래스 지원=> REST 관련 Conception만 조금 공부하면 되고, 나머지는 기존 MVC만 알면 되기 까닭에재사용성이 큼
4. Spring 3 Rest 지원 #1Annotation 지원@ResponseStatus@ExceptionHandler
5. Spring 3 Rest 지원 #2ContentNegotiatingViewResolver요청 데이터 포맷에 맞춰 다양한 MIME(미디어 타입) 이나 content type으로 전달 가능ATOM, RSS, XML, JSON, OXM예)http://localhost:8080/fruit/banana.xmlhttp://localhost:8080/fruit/banana.rsshttp://localhost:8080/fruit/banana.htmlAccept : application/xmlAccept : application/jsonAccept : application/html
24. Content NegotiationHTTP 1.1 스펙에서 정의의미media type, 언어, 문자집합, 인코딩 등에 대해 브라우저가 제공한 선호도에 따라 자원의 가장 적합한 표현을 선택. 불완전한 협상 정보를 보내는 브라우저의 요청을 지능적으로 처리하는 기능일반적으로 다른 프로토콜을 쓰려면, request의 “type” 파라미터를 확인하고, 이에 맞는 marshalling정보를 전달해야 한다.트위터API가 이렇게 사용되고 있음Spring MVC에서는 한번에 해결해주는 클래스 사용 ContentNegotiatingViewResolver
30. Demo에서 @XmlElement사용시 유의할 점Set메소드를 사용하려면, 다음과 같이 한다. 클래스의 멤버 필드에서 @XmlElement를 정의할 때는 set 메소드를 사용하지 않는다. @XmlRootElement(name = "fruit")public class Fruit { private String name; private int quality;@XmlElement public void setBody(Body body) {this.body= body; } public String getName() { return name; }@XmlElement public void setQuality(int quality) {this.quality= quality; } public intgetQuality() { return quality; }…}@XmlRootElement(name = "fruit")public class Fruit {@XmlElement private String name;@XmlElement private int quality; public String getName() { return name; } public intgetQuality() { return quality; }…}JAXB에서 property를 읽을 때, 잘 사용해야 하는 구조
31. Demo에서 @XmlElement사용시유의할 점Body 클래스앞에@XmlRootElement선언이 되어 있으면, Fruit 클래스 에서 @XmlElement를 사용하지 않아도 된다.@XmlRootElement(name = "body")public class Body { @XmlElement private String msg; // set/get accessory ….}@XmlRootElement(name = "fruit")public class Fruit {@XmlElement private String name;@XmlElement private int quality; private Body body; public String getName() { return name; } public intgetQuality() { return quality; }…}
33. 웹 브라우져 제약 #1GET/POST만 쓸 수 있는 웹 브라우져가 있을 수 있다. PUT과 DELETE 을 쓰기 위해서는 trick을 써야 한다.HiddenHttpMethodFilter이용Web.xml <filter> <filter-name>httpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>httpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
34. 웹 브라우져 제약 #2// spring mvc form tag<form:form method="delete"> <p class="submit"><input type="submit" value="Delete Pet"/></p> </form:form>@RequestMapping(method = RequestMethod.DELETE)public String deletePet(@PathVariableintownerId, @PathVariableintpetId) {this.clinic.deletePet(petId); return "redirect:/owners/" + ownerId;}아마도 예전처럼 내부적으로 name=“_method” value=“Delete” 하는 형태로 전달하고, Spring 서버는 이 정보를 바탕으로 구현 했을 것으로 예상<form action="POST"> <input type="hidden" id="_method" value="PUT"></form>
35. PUT/DELETE in HTMLHTML version 4 과 XHTML 1에서는 HTML form안의 HTTP 요청은 GET과 POST 방식만 허용. 그동안put/delete 메소드를 사용하려면, XMLHttpRequest를 이용하였음HTTP상에서는 ok!HTML5에서 put/delete는 사용하지 못한다고 나와 있음http://www.w3.org/TR/html5-diff/Using PUT and DELETE as HTTP methods for the form element is no longer supported.참고
