Dwarf is a modular Java framework for developing network server applications based on Internet standards. While focused on building service-based applications like Web servers, mail servers, and messaging services, it can also be used for other applications. The core consists of several packages, which provide a multithreaded kernel, security based on the standard Java 2 Platform Security architecture and the JAAS, logging, configuration, and a management system. Modularity and a fine-grained API allow one to extend the server, to reuse the existing services for a new application, or even create new services based on the existing ones.
