• Geronimo Administration Console
• #Deployer tool (command line)
• #Hot deployment (command line)

When you package your application you may include the deployment plan within the package or not. At deployment time, Geronimo will look for the geronimo-web.xml and web.xml deployment plans (or geronimo-application.xml or geronimo-application-client.xml depending the type of application) in the WEB-INF directory within you packaged application. If Geronimo can not find those descriptors it will attempt to deploy the application using defaults. If using defaults fails you will have to provide a deployment plan either repackaged in the application or providing an external deployment plan, in the following sections we will discuss further these alternatives.

Geronimo Administration Console

Anchor
GAC GAC

To install a new application via the Geronimo Administration Console the Install New Applications portlet is available by selecting Deploy New on the Console Navigation menu on the left hand side. This portlet also allows you to start automatically the application right after it was deployed.

...

These are the basic steps for installing and uninstalling applications via the Geronimo Administration Console, the following two sections will focus on the command line options.

Deployer tool

The deployer tool will allow you, among other things, install and uninstall applications via a command line. In this section we will focus on just these two tasks for the sample application, the remaining functionality is fully covered in the Deployer tool section.

...

These are not the only options and commands available for this tool, please visit the Tools and commands section for additional details.

Hot deployment

Apache Geronimo has support for Hot Deployment. This means that you can copy an application JAR file into the <geronimo_home>/deploy directory and the application will be deployed automatically. This will also work for uninstalling or refreshing applications previously deployed via this method. Alternatively, you may also copy the directory (unpacked) for the application module instead of copying a single JAR file.

Summary

In this section we has discussed three different methods for installing and uninstalling applications, one graphical, one command line and for the hot deployment you can choose command line or the GUI of your choice. While considering you are using multiple Geronimo servers as a cluster, you can deploy applications to them at one shot by using clustered deployment. For more information of this task, see Farming using Deployment for the details.
You can visit the Tools and commands section as well for further details on the available options and parameters.
