There are two places in the Control Panel where you can manage and configure apps: the App Manager, and the Components listing. The App Manager lets you manage apps in Liferay’s OSGi framework. You can use the App Manager to install, activate, deactivate, and delete apps in your Liferay instance. You can manage apps at the app suite, app, and OSGi module levels.

Unlike the App Manager, the Components listing lets you view and manage apps regardless of Liferay’s OSGi framework. The Components listing also differs by letting you view apps by type (portlet, theme, and layout template), and set app permissions. Although the Components listing lets you activate and deactivate apps, you can’t use it to install or delete apps.

First, you’ll learn how to use the App Manager.

Using the App Manager

Access the App Manager by selecting Control PanelAppsApp Manager. The App Manager lists your Liferay instance’s app suites and apps in separate tables. The bar above the first table lets you display the contents of both by category and status. You can also sort the tables by title. Click the up or down arrows to perform an ascending or descending sort, respectively. To search for an app suite, app, or module, use the search bar at the top-right. This is often the quickest way to find exactly what you’re looking for.

Each item listed in the tables contains a description (if available), version, and status. The status refers to the item’s OSGi status:

  • Installed: The item is installed in the OSGi framework.
  • Resolved: The item’s dependencies have been resolved by the OSGi framework. Resolved items can typically be activated. Note, however, that some items, like WSDD modules containing SOAP web services, can’t be activated and are intended to remain in the Resolved state.
  • Active: The item is running in the OSGi framework.

Clicking the Actions button (icon-actions.png) to each item’s right brings up a menu that lets you activate, deactivate, or delete the item.

To view an item’s contents, click its name in the table. If you click an app suite, a new table lists the suite’s apps. If you click an app, a new table lists the app’s modules. If you click a module, a new table lists the module’s components. The component level is as far down as you can go in OSGi without getting into the source code. After that, it’s turtles all the way down. At any level in the App Manager, you can use the link trail above the table to go back in the hierarchy.

For information on using the App Manager to install an app, see the article Installing Apps Manually.

Next, you’ll learn how to use the Components listing.

Using the Components Listing

Access the Components listing by selecting Control PanelConfigurationComponents. The Components listing first shows a table containing a list of portlets installed in your Liferay instance. Select the type of component to view–portlets, themes, or layout templates–by clicking the matching tab on top of the table. To configure a component, select its name in the table, or select Edit from its Actions button (icon-actions.png). Doing either opens the same configuration screen.

The configuration screen lets you view a component’s module ID and plugin ID, activate or deactivate the component, and change the component’s Add to Page permission. The component’s module ID and plugin ID appear at the top of the screen. You can activate or deactivate a component by checking or unchecking the Active checkbox, respectively. To change a component’s Add to Page permission for a role, select the role’s Change button in the permissions table. This takes you to Control PanelUsersRoles, where you can change the component’s permissions for the selected role.

Awesome! Now you know how to manage the apps installed in your Liferay instances.
