Overview

Dwarf Server Framework is a Java™ technology-based class library for developing network server applications. It has been designed mainly to support building of TCP/IP-based network servers, like web servers, mail servers, streaming servers, etc. However, we hope that it can be used for building a more general service-based applications, too.

The framework emphasizes on simple design, very concise API, lightweight implementation and a reduced learning curve. It is not an all-purpose universal wheel, but it tries to support the server development in a very clear, simple and effective way.

Main features:

• service-based modular architecture
• simple and concise API
• XML-based configuration
• application-independent authentication
• subject-based authorization
• proprietary or third party login modules
• powerful logging subsystem
• universal multi-threaded server
• generic TCP and UDP protocol handlers
• simple TCP/IP services implementation (discard, echo, time, chargen, etc.)
• various utility classes (DNS client, queues, caches, etc.)
• extensible remote management
• rich documentation with tutorials
• coding examples with source code
  

It requires Java™ 2 Runtime Environment (JRE) version 1.4 or higher for the basic runtime operation. The Java™ 2 Software Development Kit (JDK) version 1.4 or higher is required for the developing your own applications. No additional extensions are needed for the initial runtime or development setup.

Release Notes

New features in version 1.3.1:

• static client and a dynamic service for simple DNS lookups
• transparent dumping of network stream content to files
• service trees traversable in a way similar to using the "cd" command on a filesystem
• support for IP-based and hostname-based filtering of network hosts

See the Changes page for the complete list of changes.
