'''Java Work Framework''' is a simple, but powerful [[Java (programming language)|Java]] framework providing [[Computer network|Network]](New I/O Socket), [[Database]], [[Exception handling]] and [[Philosophy:System|System]] functionality. It is [[Open source|open source]], object-oriented and event driven.

==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|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 [[Transport Layer Security|SSL]]
* Exchanging data encrypted through XXTEA, XOR algorithms

==Code snippets==

Multicast:
<pre>
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()) );
} } );
</pre>

<pre>
Multicast.send( "Lorem ipsum dolor ...", "230.0.0.1", 35098 );
</pre>

Database:
<pre>
    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);
</pre>

==Requirements==
* JDK 1.6 (Mustang)
