Sun GlassFish Web Space Server 10.0 Administration Guide

Source Code

If you have extended Web Space Server or have written portlet or theme plugins, they should be stored in a source code repository such as Subversion, CVS, or Git. This repository should be backed up on a regular basis to preserve your ongoing work.

If you are extending Web Space Server with the Extension Environment, you will want to make sure that you also store the version of the Web Space Server source on which your extension environment is based. This allows your developers convenient access to all of the tools they need to build your extension and deploy it to a server.
