Use the developer tools simplifies the process of configuring a Liberty collective by providing convenient utilities for creating collective controllers or joining collectives. For more information about Liberty collectives, see Configure a Liberty collective.

   Create a collective controller can be done only with the following editions:

   2. In the Keystore password field, type a password for the collective.

   3. Click Finish.

   An information dialog appears after the collective configuration is complete. This dialog informs you that server.xml was already updated to include the generated configuration file. If there are instructions to add the configuration lines to the server.xml in the console output, they can be ignored. However, Administrative Security and other settings might still need to be configured within the included configuration file before any collective members can join.
