Administration FAQs

Which `asadmin` Commands are Supported?

Use asadmin list-commands to determine which commands are supported and available for use. For related information, see "Subcommands for the asadmin Utility" in GlassFish Server Open Source Edition Administration Guide.

Application FAQs

Eclipse is a development environment that provides a framework, tools, and runtime for deploying and managing software. The GlassFish plugin for Eclipse provides important changes to better support GlassFish Server and to provide optimal redeployment of web applications. For more information, see the GlassFish Plugins page: http://glassfishplugins.java.net.

Extensibility FAQs

How Do I Develop Add-On Components?

See the Eclipse GlassFish Server Add-On Component Development Guide for complete details.

How Do I Add Containers?

GlassFish Server has a highly modular architecture that enables you to add new types of containers that handle many application types, not just Java EE. GlassFish Server defines a service provider interface (SPI), which container developers implement. The GlassFish Server framework then invokes the container’s implementation of the SPI to detect, deploy, and manage applications of the new type.

For more information, see "Adding Container Capabilities" in Eclipse GlassFish Server Add-On Component Development Guide.

How Do I Extend the Administration Console?

See "Extending the Administration Console" in Eclipse GlassFish Server Add-On Component Development Guide.

Update Tool FAQs

How Do I Use Update Tool to Extend My GlassFish Server Installation?

Enterprise Server provides an administrative tool called Update Tool that enables you to install updates and add-on components to your existing Enterprise Server installation.

Update Tool can be accessed as a standalone graphical tool from the command line (using the updatetool command from as-install-parent`/bin`), or as a browser-based graphical tool from the Administration Console (using the Update Tool node). For more information about Update Tool, see "Update Tool" in Eclipse GlassFish Server Administration Guide.

Note:

To update or remove installed components, you must use the standalone graphical Update Tool, not the Administration Console Update Tool.

A command-line interface is also available for Update Tool. This interface uses the pkg command and enables you to perform most of the tasks provided by the standalone graphical version. For more information about the pkg command, see "Extending and Updating GlassFish Server" in Eclipse GlassFish Server Administration Guide.
