#### To deploy an EJB module

1. On the Deploy Enterprise Applications/Modules page, specify the location of the JAR file to deploy.

   The server machine is the host that is running the application server domain administration server. The client machine is the host on which you are viewing the Admin Console through a browser.

   - If the file resides on or is accessible from the client machine, click the radio button to specify a package file to upload to the Application Server.

     Click Browse to browse to the file, or type the full path to the file.

   - If the file resides on the server machine, or to deploy an unpackaged application from an exploded directory, click the radio button to specify a package file or a directory path that must be accessible from the server.

     Type the full path name to the file or directory. Deploying from an exploded directory is for advanced developers and is not recommended for production environments.

2. Specify the settings for the module.
   1. In the Application Name field, either retain the default name, which is the prefix of the file name, or type another name.

      The default name appears if you chose to upload a file. The application name must be unique.

   2. To disable the module so that is unavailable after Deploy Enterprise Applications/Modules page, deselect the Status: Enabled check box.

      By default, an module is available as soon as it is deployed.

   3. Choose a high availability setting.

      To enable high availability for the module, select the Availability checkbox. If availability is enabled for an module, it must also be enabled at all higher levels (named configuration and web container or EJB container) as well.

   4. To verify the structure and contents of the file before Deploy Enterprise Applications/Modules page, select the Run: Verifier checkbox.

      Verification of large applications can be time-consuming. Verify the file if you suspect it is corrupt or non-portable.

   5. Enter the path to any libraries (JAR files) that the EJB module requires.

      The libraries must be accessible on the server.

   6. Optionally enter a brief text description of the EJB module.
   7. If you are running a domain with cluster profile, choose the targets to which to deploy the module.

      From the list of available targets, choose the target or targets and click Add. Targets can be clusters or stand-alone server instances. If you do not select a target, the module is deployed to the default server instance `server`.

3. Click OK to deploy the module.
