JSF Component Behaviors

The document discusses JavaServer Faces (JSF), an MVC framework for building web interfaces. It provides: - An overview of JSF concepts like managed beans, expression language, navigation rules, and components. - Examples of using JSF for static and dynamic navigation between pages, including declaring beans and navigation rules in faces-config.xml. - How JSF handles form submission and uses managed beans to represent request parameters and output data to results pages.

JSF 2 life cycle consists of 6 phases: restore view, apply request values, process validations, update model values, invoke application, and render response. Managed beans are JavaBeans that can be accessed from JSF pages and are used to store data. Facelets is the templating language used by JSF 2 that replaced JSP. Navigation between pages can be done through configuration, implicit navigation based on action outcomes, or redirection. New features in JSF 2.2 include faces flows for page flows, HTML5 support, and a file upload component.

This session will provide a complete tour of using the Spring MVC framework to build Java Portlets. It will include an in-depth review of a sample portlet application developed using the latest features of Spring MVC, including Annotation-based Controllers. If you are writing Portlets and using Spring, this session is for you. We'll begin by discussing the unique differences and challenges when developing Portlets instead of traditional Servlet webapps. Then we'll talk about the unique approach that Spring MVC takes towards Portlets that fully leverages the Portlet lifecycle, instead of masking it like many other frameworks. We'll take an extensive tour of a sample application so we can see all the unique pieces of the framework in action. Finally we'll conclude with discussion of the upcoming support for the Portlet 2.0 (JSR 286) specification that will be part of Spring 3.0.

JSF is a Java specification and framework for building component-based user interfaces for web applications. It uses the MVC design pattern with reusable UI components, and handles tasks like data conversion, validation, event handling and navigation. The JSF architecture includes a component tree, request processing lifecycle and rendering model. New features in JSF 2 include Facelets as the default view declaration language, annotation-based configuration, standardized Ajax support, and improved error handling. Developing with JSF involves creating managed bean models, registering them, building pages with UI components, defining navigation, and configuring the web application in web.xml.

It follows the model-view-controller (MVC) pattern to separate application behavior, user interface, and data access. The goals of ASP.NET MVC include testability, friendly URLs, leveraging existing ASP.NET features, and full control of HTML. It also discusses how ASP.NET MVC works, including routing, controllers, actions, and views. Demos are provided for basic routing and controllers as well as models, HTML helpers, forms, and validation.

The key technologies discussed are JSF tags, configuration files, components and validators as well as the steps involved in an AJAX request like creating an XMLHttpRequest object and processing the response.

ASP.NET AJAX allows developers to call remote services from client-side code by exposing server-side code as RESTful services or SOAP web services. It uses JSON serialization to exchange data between the client and server and allows defining callbacks for asynchronous method calls. Page methods provide another way to expose server logic by decorating methods in code-behind classes with the WebMethod attribute.

Kief Morris rethinks the infrastructure code delivery lifecycle, advocating for a shift towards composable infrastructure systems. We should shift to designing around deployable components rather than code modules, use more useful levels of abstraction, and drive design and deployment from applications rather than bottom-up, monolithic architecture and delivery.

Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states. In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing. Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

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.

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.
