Payara Serverの管理タスクで最も多いものの1つは、他のWebサーバーと同様に、HTTPプロトコルやPayara Serverへのリモート・アクセスをセキュアにするための電子証明書のセットアップです。自己署名証明書または信頼できる認証機関の署名入り証明書のいずれかをお持ちでしょうが、どちらの場合も証明書をPayara Serverのドメインに追加してセキュアな通信に用いるのはとても簡単です。

In the previous guide, we’ve seen how we can configure the Payara Platform to connect to a database and use the datasource from an application. This guide walks you through the process of building an application to store and retrieve data from the database.

Introduction

OpenID Connect is a security mechanism for an application to contact an identity service, verify the identity of the End-User based, and obtain End-User information using REST API's in a secure way.

Java EEプロジェクトを作成するにあたって、Eclipseにサーバーを定義してアプリケーションをIDE上でテストできるようにしておくことは重要です。生成物をビルドして手動でPayara Serverにデプロイするよりも、作業がずっとスムーズになります。

This debugging guide will help you to diagnose and detect the cause of errors in your application by debugging Payara Server or Payara Micro.

Eclipse MicroProfile is a framework that brings innovative technology to enterprise applications. Both Payara Server and Payara Micro provide the most recent MicroProfile version as soon as possible. Along with the aim to simplify development of microservices and cloud deployment, MicroProfile is continually adopting other modern approaches and patterns like reactive programming.

A REST Service in Java EE can be created using JAX-RS. The contents of such service can be consumed using ordinary HTTP requests to a URL. URLs are typically kept simple and have a logical pattern, so it's easy to type them manually in e.g. a browser. This is different from SOAP, which essentially uses HTTP as well, but is designed to be rather complex and therefor making it not so easy to quickly test something in a browser.

If you're building a REST service, then that REST service will expose some kind of data or will allow some kind of interactions with a server. For instance, consider a Facebook REST service that allows you to retrieve your chat history. Naturally you don't want just anyone looking at that history, hence the need for security.

JSF is a component oriented MVC (Model View Controller) framework that's a part of Java EE. It comes with a small set of basic components (widgets), a templating engine, and facilities for converting and validating input. JSF strongly builds on other APIs in Java EE. Request handling is build on top of the Servlet API, binding UI components to Java code is mostly done via Java EE's Expression Language, with the Java code being (named) CDI beans. Validation is often delegated to Bean Validation.
