Java Work Framework

From Seo Wiki - Search Engine Optimization and Programming Languages

Java Work Framework is a simple, but powerful Java framework providing Network(New I/O Socket), Database, Exception handling and System functionality. It is open source, object-oriented and event driven.

[edit] 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.

[edit] 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

[edit] Security

• Securing socket communication through SSL
• Exchanging data encrypted through XXTEA, XOR algorithms

[edit] 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);
