What is Spring? Component-based development for Java

1 month 1 week ago

Spring is perhaps the best of the component-based frameworks that emerged at the turn of the 21st century. It vastly improves the way that developers write and deliver infrastructure code in Java-based applications. Since its inception, Spring has been recognized as a leading framework for enterprise Java development. As an end-to-end application framework, Spring mirrors some of the Java EE capabilities , but it offers a combination of features and programming conventions you won't find elsewhere.

Eclipse Jakarta EE arrives

2 months 1 week ago

The Eclipse Foundation has released the Jakarta EE 8 platform and web profile specifications, which constitute Eclipse’s implementation of Java Enterprise Edition 8. The group also made available a Jakarta EE application server and open source technology compatibility kits (TCK) for testing compliant implementations.

The Jakarta EE specifications can be accessed at the project website. Specifications range from Jakarta Annotations, which represent semantics for declarative programming, to Jakarta Server Pages, which define a template engine for web applications.

Along with the specifications, Eclipse is releasing Eclipse GlassFish 5.1, an open source application server that implements the Jakarta EE Platform. Jakarta EE 8-compliant servers are expected from various Java server vendors; IBM’s Open Liberty server already has been certified as Jakarta EE 8-compatible.
