## Key Features

### Modularity and Extensibility

The modular architecture of GlassFish v3 Application Server enables you to download and install only the modules that you require for the applications that you are deploying. As a result, start-up times, memory consumption, and disk space requirements are all minimized. This modular architecture also enables the extension of the Application Server's basic functionality through addition of modules through the Update Tool. The Update Tool is developed through the Update Center project.

### Scripting Language Support

GlassFish v3 Application Server Technology Preview 2 supports the Ruby scripting language by providing native support for JRuby. This support enables GlassFish v3 Application Server to be applied beyond developments that are centred on Java technology.

### Java EE Web Tier Support

GlassFish v3 Application Server Technology Preview 2 supports the web tier of the Java EE specification to enable the deployment of web applications. GlassFish v3 Application Server implements the following Java EE standards:

- JAXB 2.0
- Java Persistence API 1.0
- Java Server Faces 1.2
- Java Server Pages 2.1 (JSP 2.1)
- Java Server Pages Standard Tag Library (JSTL) 1.2
- Streaming API for XML (StAX)
- Java API for XML based Web Services 2.1 (JAX-WS 2.1)
- Common Annotations for the Java Platform 1.0 (CAJ 1.0)

For a complete list of the Java EE technologies included, see the Release Notes.

### Web Services Interoperability Technologies (WSIT) Support

Sun is working closely with Microsoft to ensure interoperability of Web services enterprise technologies such as message optimization, reliable messaging, and security. WSIT is a product of this joint effort. WSIT is an implementation of a number of open web services specifications to support enterprise features. In addition to message optimization, reliable messaging, and security, WSIT includes a bootstrapping and configuration technology. Starting with the core XML support currently built into the Java platform, WSIT uses or extends existing features and adds new support for interoperable web services, including:

- Bootstrapping and Configuration
- Message Optimization Technology
- Reliable Messaging Technology
- Security Technology

### Open Source and GlassFish Community

In June 2005, Sun launched the GlassFish community with the goal of developing a free, open source, commercial-grade application server that implements the newest features of the Java EE platform and related enterprise technologies. GlassFish v3 Application Server is based on the source code that is developed by the GlassFish community.

Discussion within the GlassFish community is conducted through the following channels:

- Forums for the GlassFish community
- Mailing lists for GlassFish community
