Java Work Framework

History

It was originally designed and implemented by Ivan Penev back in 2005 as a network layer capable to handle around 10,000 socket connections. Then it gradually included the most common functionality a programmer may need - socket communication, simple database access, reading external resources as files, URLs, etc.

Features

Its main focus is to hide behind simple wrappers existing Java functionality and to provide general application exception handling mechanism. In short it supports:

Java NIO Socket Framework

15,000+ socket connections. Sending/receiving 5000 java objects per second between 2 computers works great.

Multicast

Unicast(UDP) support

Pluggable protocols through in and out filters

Easy-to-use database layer

Custom JAR files loader

Security

Securing socket communication through SSL

Exchanging data encrypted through XXTEA, XOR algorithms

Code snippets

Multicast:

Multicast.listen( "230.0.0.1", 35098, new IEventListener() { public void onEvent( IEvent evt ) { MulticastDataEvent dataEvt = (MulticastDataEvent)evt; System.out.println( "data-bytes:" + DebugUtil.toString(dataEvt.asByteArray()) ); } } ); Multicast.send( "Lorem ipsum dolor ...", "230.0.0.1", 35098 );

Database:

Database db = Database.createInstance(); db.setUrl("jdbc:postgresql://localhost/testdb"); db.setUsername("testuser"); db.setPassword("test123"); SQLInsert insertOp = new SQLInsert("persons"); insertOp.addData("person_fname", "Mike", "person_lname", "Johnson", "birthday", Convert.toDate("1971-08-01"), "country_id", "de", "single", true); int affectedRows = insertOp.execute(); System.out.println("Affected rows = " + affectedRows);

Requirements

JDK 1.6 (Mustang)
