GlassFish Server provides an administrative tool called Update Tool that enables you to install updates and add-on components to your existing GlassFish Server installation. Update Tool can be accessed as a standalone graphical tool from the command line or as a browser-based graphical tool from the Administration Console. For more information about Update Tool, see Update Tool in Oracle GlassFish Server 3.0.1 Administration Guide.
Use the updatetool command:
If Update Tool is not installed, you will be prompted to install it. Install the tool if desired, then use the updatetool command to start the tool. Extensive online help is available from the tool's Help menu.
A command-line interface is also available for Update Tool. The command-line interface uses the pkg command and enables you to perform most of the tasks provided by the graphical version. For more information about the pkg command, see Chapter 10, Extending GlassFish Server, in Oracle GlassFish Server 3.0.1 Administration Guide.
At least one GlassFish Server domain must be started before you launch the Administration Console.
