Create a Liberty feature using developer tools

We can use the WebSphere Application Server Developer Tools to write our own features, and install them into an existing Liberty profile server, or to package them for delivery to the users.

To develop a Liberty feature in the WebSphere Application Server Developer Tools, we create a Liberty feature project and target it to the WebSphere Application Server Liberty profile version 8.5.5 or later.

You add OSGi bundles containing classes and services that implement the function provided by the Liberty feature. If the feature provides any API packages to OSGi applications, or SPI packages to features in other product extensions, we can declare those packages in the Liberty feature manifest file.

We can export the liberty feature as a compressed file that can be extracted over an existing WebSphere Application Server Liberty profile to extend its capabilities.

For more information on creating Liberty features, see Product extension.
