# Install a Web application

Installing a Web application refers to making its physical file or directory known to WebLogic Server. A Web application can be installed as `WAR` archive or exploded `WAR` directory. After you have installed the Web application, you can start it so that users can begin using it.

To install a Web application:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane of the Administration Console, click Deployments.
3. In the right pane, click Install.
4. Using the Install Application Assistant, locate the `WAR` file or exploded `WAR` directory that corresponds to the Web application you want to install. If you specify an exploded directory, WebLogic Server installs all components in and below the specified directory.
5. When you have located the file or directory to install, click Next.
6. Specify whether you want to target the installation as an application or a shared library.
7. Click Next.
8. Select the servers and/or clusters to which you want to deploy the Web application.

   Note: If you have not created additional Managed Servers or clusters, you will not see this assistant page

9. Click Next.
10. Optionally update settings about the deployment. These settings include:
    - The deployed name of the Web application.
    - The security model that is applied to the application.
    - How the source files (WAR or exploded directory contents) are made available to targeted Managed Servers and clusters.

    Typically, the default values are adequate.

11. Click Next.
12. Review the configuration settings you specified, and click Finish to complete the installation.

    Note: If you install an application that follows the below directory structure and there is no deployment plan in the `/plan` directory, WebLogic server automatically creates a deployment plan for you.

    - app-root
    - /app
    - /plan
13. If you chose to immediately go to the deployment's configuration screen, click the tabs to set additional configuration settings for the Web application. If you chose to change this information later, the Administration Console returns you to the Deployments table, which should now include your newly-installed Web application.
14. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
