プロジェクトの歴史

Open Liberty comes from IBM Liberty, which started in 2012 and was opened on GitHub in 2017. The open project implements Jakarta EE and MicroProfile and provides the codebase underneath WebSphere Liberty.

Jakarta EE 9.1 Web Profile is the web subset of the post-`javax` namespace generation. Open Liberty documents `webProfile-9.1` as combining the Liberty features that support the Jakarta EE 9.1 Web Profile, including Servlet 5.0, CDI 3.0, JSON-B 2.0, JSON-P 2.0, RESTful Web Services 3.0, Persistence 3.0, and WebSocket 2.0.

採用の歴史

Open Liberty announced beta compatibility with Jakarta EE 9.1 Web Profile and Platform on the week Jakarta EE 9.1 was made available, with Java SE 8 and Java SE 11 coverage. That made Web Profile 9 a practical testing target for applications moving to the `jakarta.*` APIs without adopting the full platform bundle.

The package's adoption value is especially migration-focused: it lets teams validate web applications against the Jakarta EE 9 namespace change while staying within the smaller Web Profile surface.

使われ方

Operators and developers enable the profile with `<feature>webProfile-9.1</feature>` in `server.xml`. In practice, that profile is enough for many web and REST applications that need CDI, Servlet, JPA, JSON, REST, validation, security, Faces, Pages, and WebSocket but not full-platform messaging or connector APIs.

The Homebrew formula gives users a named install for that standards subset. It complements Open Liberty's plugin and container workflows, which can also install the runtime and server features for build and deployment automation.

パッケージ好きにとっての重要性

This package is a compact example of compatibility metadata encoded in a package name: `webprofile9` signals both the smaller Web Profile API set and the Jakarta EE 9 namespace generation.

For catalogs, it should not be collapsed into the generic Open Liberty package without losing useful dependency and migration information. Web Profile 9 has a different API surface from both Web Profile 8 and the full Jakarta EE 9 platform package.
