This page provides a starting point for finding out how
to develop applications for the WebSphere® Application
Server Liberty profile, which provides a highly composable, lightweight,
and very quick, application server.

New feature:
The Liberty profile
support in WebSphere Application
Server delivers a new, lightweight profile of the application server
for web and OSGi applications, along with a simplified configuration
approach for developers. Key benefits of the Liberty profile include,
but are not limited to, the following capabilities:
- Free and frictionless download for development purposes
- Ultra lightweight modular runtime environment, with an install
size of under 50 MB
- Very fast startup time; for example, less than 5 seconds for simple
web applications
- Simplified configuration for quick time to productivity
- Java EE and OSGi application
deployment support for web applications
- LDAP registry support
- Deployment, as a package, of an application and configured server
- Managed, centralized deployment of a packaged application and
server
- Availability of WebSphere Application
Server Developer Tools as Eclipse plug-ins for broad tooling support
- Platform support for distributed platforms, z/OS®, and Mac OS
Very fast restart times, coupled with its small size, dynamic
behavior, and ease of use, make the Liberty profile a good option
for developers building web applications that do not require the full Java EE environment of traditional
enterprise application server profiles. Familiar WebSphereApplication Server enterprise
qualities of service, such as security and transaction integrity,
are enabled as required.
