Modern web applications are moving toward JavaScript-based rich clients that communicate with RESTful APIs and services. The browser acts as the rich client using HTML5, CSS3, and JavaScript, while the server side provides cloud-hosted RESTful services using technologies like Spring and NoSQL databases for scalability. This shifts complexity from server-side rendering to the client while taking advantage of the cloud. Key challenges include implementing modularity in JavaScript and supporting offline use, cloud deployment, API design best practices, and testing.
1) The document discusses reactivity in modern frontend frameworks like Angular, React, and Vue. 2) It explains the different approaches to reactivity including Angular's use of Zone.js for change detection, React's functional components approach, and Vue's reactive state. 3) The document also covers alternatives within frameworks like OnPush change detection in Angular and using observables, as well as design patterns like separating state from components.

This document discusses integrating Backbone.js with Spring 3.1. It begins with an overview of new features in Spring 3.1, such as cache abstraction, bean definition profiles, and Java-based configuration. It then provides an introduction to Backbone.js, explaining how it gives structure to web applications using models, collections, views and routers. The document demonstrates how to integrate Backbone.js and Spring 3.1 by using Spring to provide a RESTful JSON API for Backbone models and collections to communicate with, while keeping the UI rendered separately using Backbone views. It provides examples of tasks being managed through GET, POST, PUT and DELETE requests to the Spring API.
Overview of JAX-WS technology for web services (Java API for XML Web Services). JAX-WS is the core Java web service technology for Java EE applications. It provides a unified client and server-side API for writing SOAP/WSDL based web services. JAX-WS is platform independent. Many Java platforms like Glassfish, Axis2 or CXF support JAX-WS. Thus services developed with JAX-WS on one platform can be easily ported to another platform. JAX-WS is based on annotations like @WebService thus greatly simplifying the development of web services. POJOs (Plain Old Java Objects) can be simply annotated with JAX-WS annotations thus turning these into web service implementations. JAX-WS is the core web service technology according to JSR-224 affording basic web service functionality. WSIT (Web Service Interoperability Technology) sits on top of JAX-WS and adds enhanced functionality like security, reliability and transactions. WSIT is the standard Java WS protocol stack beyond basic WS functionality (SOAP, WSDL) to achieve interoperability between Java and .Net (for more complex applications that go beyond simple WS requests).
This document provides an overview of Spring MVC, the model-view-controller framework for building web applications in Spring.

It utilizes configuration files and custom tags to coordinate requests between components.
This document provides an overview and introduction to KnockoutJS, a JavaScript MVVM library created by Steve Sanderson. It discusses key features of KnockoutJS like observable properties, observable arrays, and bindings. Observable properties allow automatic updating of the UI when the model changes. Bindings provide a simple way to connect UI elements to the model. The document also covers how to set up a basic Knockout app with a view model, bindings, and applying bindings. Additional resources for learning KnockoutJS are provided at the end.
The document describes contract-first and contract-last approaches to developing web services using Spring. It provides details on defining the service contract, creating message endpoints, mapping messages to endpoints, configuring marshaling and exceptions, and serving WSDL files. The key aspects are defining the XML schema first in contract-first, while contract-last derives the schema from the code. It also discusses using JDOM or marshalling endpoints to process messages.
Spring provides tools for building multi-client web applications, including support for mobile clients and REST APIs. It includes the Spring MVC framework for building web UIs, the RestTemplate for consuming REST services, and tools like Spring Android for building native Android apps that integrate with REST backends.

Đây chính là một ví dụ hoàn hảo để vận dụng Rails engine vì các chức năng sẽ không thay đổi nhiều, bạn dễ dàng trừu tượng hóa những tính năng đó trong một engine. Vào buổi seminar tới đây, tôi sẽ trình bày một số điểm cơ bản vô cùng bổ ích về Rails engine, giúp cho các bạn có thêm kiến thức áp dụng trong công việc
Spring MVC is a web MVC framework that provides a reusable presentation layer for web applications. It removes boilerplate code and standardizes navigation flow and validation. Spring MVC controllers handle HTTP requests and delegate work to service objects. It uses the front controller design pattern and is view-agnostic, allowing different view technologies. Spring MVC applications are configured through XML files and use annotations for components and request mapping.
