Enabling the Connections app registry service for customization

To leverage custom config extensions, enable the app registry service. You need Component Pack installed to do so. If Component Pack is not available, you can inject customizations using window-scoped JavaScript objects. For more information, refer to Customizing through window-scoped JavaScript objects.

By default, Connections applications do not attempt to make requests to the app registry service if the app registry service has not been deployed as part of a Component Pack installation.


When adding new entries to the App Registry, it is important to ensure that no other entries with the same namespace are enabled or active within the system. This is to prevent conflicts, maintain system integrity, and ensure seamless functionality across all applications.


To enable the app registry service:

  1. Locate the file WAS_HOME\profiles\WAS_Profile\config\cells\Host_name\LotusConnections-config\LotusConnections-config.xml.

  2. In the file, locate the sloc:serviceReference section. where serviceName="extensionRegistry".

  3. Check that both the enabled and ssl_enabled properties are set to true.

  4. If they are not set to true, update the configuration file so the section looks as follows. Replace admin\_replace with the appropriate server domain:

    <sloc:serviceReference bootstrapHost="admin\_replace" bootstrapPort="admin\_replace" clusterName="" enabled="true" serviceName="extensionRegistry" ssl_enabled="true">
        <sloc:static href="admin\_replace" ssl_href="admin\_replace"/>
        <sloc:interService href="admin\_replace"/>
  5. Sync your changes and restart the server.

Sample customization using the Connections app registry

In this example, you can use custom style extensions to update the Connections colorway to green. Refer to the following procedure, which involves creating a custom config extension:

  1. Log in to your HCL Connections environment as an administrative user and navigate to the URL https://__CONNECTIONS_DOMAIN__/appreg/apps.

Defining object properties in the app registry configuration

The most important properties in the app registry configuration are the type and payload properties within the extensions array:

  • type specifies to which component the extension relates. Currently, the following types are available:

    Extension Type Description
    com.hcl.connections.nav Customization of the menu entries on the side navigation bar Customization of header elements and general theming via custom styles
    com.hcl.connections.banner Configuration of the administrative banner and its content Customization of the search box and the connected search application
    com.hcl.share.extension Extension of the Connections share actions and targets Customization of the Important To Me bar
    com.hcl.appreg.ext.templatedLink Extension of communication options for the business card Extension of the Connections welcome tour
  • payload is specific to the individual component and the mandatory and optional properties that the component supports. For more information around the expected values for payload, refer to the customization topic for each component.

In addition to type and payload, extensions also expect name and title properties that provide context within the app registry overview page or are used to render labels on the UI, respectively.
