QuickServer is an open source Java library/framework for quick creation of robust multi-client TCP server applications. With QuickServer you can concentrate on just the application logic/protocol on hand.
QuickServer provides an abstraction over the ServerSocket, Socket and other network and input output classes and it eases the creation of powerful network servers.
QuickServer Example programs demonstrating the use of the library can be found with the QuickServer distribution [examples folder]. Latest examples, documentation is available through the website.

Brief Architecture
QuickServer divides the application logic of its developer over eight main classes,

[#] = Any one of these have to be set based on default DataMode for input. The default DataMode for input is String so if not changes you will have to set ClientCommandHandler.

Major Features
  * Create multi-client TCP server applications.
  * Support for secure server creations: SSL, TLS. Secure
  * Support for thread per client (multi-threaded) - Blocking Mode.
  * Clear separation of server, protocol and authentication logic.
  * Remote administration support: QSAdminServer (With support plugable application commands).
  * Command Shell for local administration of server.
  * GUI based remote administration: QsAdminGUI (with support for plug-ins - PluginPanel)
  * Restart or Suspend the server without killing connected clients.
  * Inbuilt pools for reusing of threads and most used Objects.
  * Full logging support [Java built in Logging].
  * Support for sending and receiving Strings, Bytes, Binary and serialized java objects.
  * Support for identifying and searching a client. ClientIdentifiable
  * Support for xml configuration with ability to store application specific data in the same xml.
    [View Sample]
  * Support for xml Based JDBC Mapping - DBPoolUtil.
  * Support for Service Configurator pattern. Service
  * Support for restricting access to server by ip address.
  * Support for loading/reloading application jar from xml.
  * Ability to add process hooks into QuickServer. ServerHook, InitServerHook
  * Ability to specify maximum number of clients allowed.
  * Support for negotiating secure connection over normal tcp connection.
  * Nice easy examples come with the distribution - FTPServer, CmdServer, EchoWebServer, ChatServer, SecureEchoWebServer, XmlAdder, PipeServer, Filesrv.

Whats New in 2.1.0 ?
  * Added support for uptime in Host (QuickServer Client)
  * Supports null/no banner when server starts
  * Fixed load pattern logic RandomLoadPattern, RoundRobinLoadPattern (was using index when client key was set)
  * Added getHighestActiveCount() method to Object Pools
  * Added getHighestActiveClientCount method to QuickServer object
  * Defaulted SSL to TLS
  * Bug fix for ThreadPool not reducing to max ideal (stay in wait state n increase over time)
  * Bug fix for Client (HashedLoadPattern)   * Disabled non blocking mode (no more supported)
