Inhalt: Having multiple users for your applications is great, right? More often than not, you probably didn't spend all that time developing your app just to have one single person use it. Of course, the moment you have more than one user running your Java application, you have a whole set of new problems. In this course, instructor Tayo Koleoso shows the various and frustrating ways accessing runtime data can fall apart in a multiuser Java application. Follow along with Tayo as he takes a deep dive into Java troubleshooting to show developers how to identify, prevent, and solve data access and consistency issues in a multithreaded environment. Whether you're working in an SQL database or accessing simple class variables, Tayo gives you tools and tips to help you predict and recognize where multithreading can go wrong. Umfang: 00:58:55
Inhalt: Concurrency and its related problems are common in enterprises. But developers who can effectively troubleshoot these issues-and write thread-safe code-are often not as easy to find. In this course, instructor Tayo Koleoso helps equip Java developers with best practices for identifying sources of blocked threads, as well as tips for preventing and solving latency issues in multithreaded Java applications. Tayo goes over the coding practices and Java platform techniques that may be slowing down your application, including how parallel Java streams-which can be convenient and great for easy multithreading-present risks and pitfalls. He also highlights the different tools and resources that can help you identify what's slowing down your application. Discover how to work with Java Mission Control (JMC) to identify blocked threads in your Java virtual machines (JVMs), how to use the Java Flight Recorder (JFR) to identify blocked threads and monitor your JVM, and more.

Inhalt: Learn how to develop modern and lightweight web services using Java Enterprise Edition (EE) 8. Instructor Tayo Koleosho begins by providing some context, explaining why we develop web services, how SOAP and REST differ, and what's new in Java EE 8. He then shows Java developers how to implement SOAP web services and RESTful APIs, such as how to design and develop a RESTful service using the Java API for RESTful Web Services (JAX-RS). Learn about testing with Postman, validation and error handling in JAX-RS, logging and monitoring in JAX-RS and JAX-WS, API security using JSON Web Token (JWT), and more. Umfang: 04:16:55.00
Inhalt: The Java EE specification is the industry standard for building enterprise-level web applications. In this course, instructor Eyitayo Koleoso focuses on JSF and shows Java programmers how to use this platform to build robust, secure Java EE web applications. Discover how to set up a JSF project, build a JSF page using Facelets, use Ajax support in JSF, secure your JSF web app, combine JSF with other frameworks, and more. Umfang: 03:14:19.00
Inhalt: PrimeFaces-the popular open-source UI framework for JavaServer Faces (JSF)-boasts features that allow developers to apply themes to their apps, leverage over 100 easy-to-use components, and more. In this course, learn how to use PrimeFaces in your Java Enterprise Edition (EE) web application. Instructor Eyitayo Koleoso helps you get started by explaining how PrimeFaces differs from standard JSF. He also shares how to set up and configure PrimeFaces and goes over the broad categories of PrimeFaces components. He then dives into theming, sharing how to configure your PrimeFaces theme and switch themes dynamically. He also covers how to display data with PrimeFaces, discussing Ajax exception handling and how to execute JavaScript from the server side. To wrap up, he goes over how to troubleshoot Ajax issues and shares PrimeFaces best practices. Umfang: 01:39:57.00
