The content on docs.sun.com (DSC) was converted in December to the new format and has now been republished to the new home (Oracle GlassFish Server 3.0.1 documentation is here). The DSC site is scheduled to be shut down and a redirect
All Sun-originated products have always been well documented and in the case of GlassFish 3.0.1, that's more than 30 different guides, ranging from the Installation Guide to the Application Development Guide or the Troubleshooting Guide.
Complete GlassFish 3.1 documentation will be posted when the product releases next month in PDF format for GlassFish Open Source Edition, and a choice of HTML and PDF for Oracle GlassFish Server. If you're looking for older Application Server-related documentation, check out this landing page.
