WebSphere Application Server Liberty Core: Overview

WebSphere® Application Server Liberty Core is a lightweight Liberty-based edition. With WebSphere Application Server Liberty Core, you can rapidly build and deliver web applications that do not require the full Java™ EE stack.

WebSphere Application Server Liberty Core is based on the developer-friendly WebSphere Application Server Liberty. By using WebSphere Application Server Liberty, you can create applications corresponding to the Java EE6 Web Profile specification. You can quickly develop and deploy Web Profile-centric applications so that your business can respond quickly to enterprise and market needs. The capabilities that WebSphere Application Server Liberty Core provides are a subset of the capabilities that are provided in the WebSphere Application Server Liberty and WebSphere Application Server Network Deployment Liberty editions.

WebSphere Application Server Liberty Core offers you the following benefits:
  • A lightweight edition, which contains the subset of Liberty that corresponds to the Java EE Web Profile specification.
  • Excellent development and production runtime environments for web applications.
  • A smaller footprint for faster download and startup, giving more development time and faster time to deployment.
  • Ease of packaging applications for deployment, including configuration.
  • The ability to run applications that are written for WebSphere Application Server Liberty Core on WebSphere Application Server traditional and Liberty.
  • The ability to extend the Liberty capabilities by adding custom features that use a product extension System Programming Interface (SPI).

The WebSphere Application Server Liberty Core edition focuses on Web Profile capabilities such as servlet, JSP, JSF, and EJB-Lite. WebSphere Application Server Liberty Core has a different programming model from other WebSphere Application Server editions. For example, WebSphere Application Server Liberty Core does not include Java Message Service (JMS) or Web Services, making Liberty Core edition lightweight and focused on the capabilities that are needed to deliver Web Profile applications.

You can use WebSphere Application Server Liberty Core to deploy to both development and production environments. The developer environment is provided by WebSphere Application Server Developer Tools for Eclipse (WDT). You can access a WebSphere Application Server Liberty Core management option through the WebSphere Application Server, Network Deployment job manager, or Liberty-based collective controller.
Note: A WebSphere Application Server Liberty Core server can be a member of a collective, but a WebSphere Application Server Network Deployment Liberty license is required for the collective controller.
