This project is created as part of the process of transitioning Oracle Java EE 8 and GlassFish technologies to the Eclipse Foundation as described in The Eclipse Enterprise for Java Project Top Level Project Charter (https://projects.eclipse.org/projects/ee4j/charter).
Eclipse Expression Language provides the API, reference implementation and TCK for Java Expression Language, starting from the specification defined by JSR-341.
Expression Language (also referred to as the EL) provides an important mechanism for enabling the presentation layer (web pages) to communicate with the application logic (managed beans). The EL is used by several JavaEE technologies, such as JavaServer Faces technology, JavaServer Pages (JSP) technology, and Contexts and Dependency Injection for Java EE (CDI). The EL can also be used in stand-alone environments.
The top level EE4J project was created consistent with the direction described in The Eclipse Enterprise for Java Project Top Level Project Charter (https://projects.eclipse.org/projects/ee4j/charter). This project is created under the top level EE4J project as one of Oracle Java EE 8 and GlassFish technologies being transitioned to the Eclipse Foundation.
