Add and remove Liberty features

Features are the units of functionality for the runtime environment loaded into a particular server. We add features using an XML snippet in the <feature> subelement of server.xml. Changes are applied dynamically.

1. Edit...
   /path/to/liberty/wlp/usr/servers/server_name/server.xml

2. Set features...

   The set of features is enclosed within the <featureManager> element, and each feature within the <feature> subelement. For example:

   <server>
       <featureManager>
           <feature>servlet-3.0</feature>
           <feature>localConnector-1.0</feature>
       </featureManager>
   </server>

   The matching of feature names is not case-sensitive; the following example is also a valid server configuration:

   <featureManager>
           <feature>Servlet-3.0</feature>
           <feature>localConnector-1.0</feature>
   </featureManager>

3. Save changes.

Results

Your changes are applied. If the server is running, the changes are applied dynamically.
