プロジェクトの歴史

The package inherits Open Liberty's history: IBM created Liberty in 2012 for a lightweight, configurable Java runtime and opened the code in 2017 as the Open Liberty project. Open Liberty then became a public implementation base for Jakarta EE and MicroProfile while remaining the foundation of WebSphere Liberty.

The Web Profile line exists because enterprise Java standards distinguish a smaller web application subset from the full platform. Open Liberty's Web Profile 8.0 feature combines Liberty features that support the Java EE 8.0 Web Profile and is also enabled by the broader `jakartaee-8.0` and `javaee-8.0` platform features.

採用の歴史

Web Profile packages fit teams whose applications use common web stack APIs but do not need the full enterprise platform. That made them a lighter standards-compatible target for local development and packaged installs, especially for REST services and traditional WAR deployments.

Because Jakarta EE 8 preserved Java EE 8 API compatibility, Web Profile 8 served as a stable bridge for applications before the namespace migration of Jakarta EE 9.

使われ方

A Liberty server enables the Web Profile 8 feature with `<feature>webProfile-8.0</feature>` in `server.xml`. Open Liberty documents the feature as enabling APIs such as application security, Bean Validation, CDI, EJB Lite, expression language, JAX-RS, JPA, JSF, JSON-B, JSON-P, JSP, Servlet, and WebSocket.

The Homebrew formula provides the profile-specific runtime as a local package-manager install. Developers can still use the broader Open Liberty ecosystem of Maven, Gradle, Docker, and Liberty Tools around the same server configuration model.

パッケージ好きにとっての重要性

openliberty-webprofile8 is useful metadata because it tells a resolver or human that the install is the web subset of the EE 8 generation, not the full platform. That distinction affects which APIs are present and which applications can run unchanged.

It also shows how Homebrew can carry Java runtime variants that package an upstream server around standards profiles, a pattern more precise than a single monolithic `openliberty` formula.

タイムライン

• 2012: IBM Liberty was created as a modular Java runtime.
• 2017: IBM opened Liberty's source as Open Liberty.
• 2019: Jakarta EE 8 continued the Java EE 8 API level under the Eclipse Foundation.
• Open Liberty documentation defines `webProfile-8.0` as the Web Profile 8.0 convenience feature and lists `jakartaee-8.0` and `javaee-8.0` as features that include it.
