JSF components and utilities that can be used with any JSF implementation. This library is compatible with both JSF1.1 and JSF1.2; however for JSF1.2 users there is an alternative build of Tomahawk available that takes advantage of JSF1.2 features to offer some additional benefits.

There is a newer version: 1.1.14

// Loggers
//
//  Loggers are pretty simple classes, that should have 1 method, called 
//  'log'. This is called with 2 arguments, the first one is the message to
//  log and the second is the severity, which can be 0 or some other false
//  value for debug messages, 1 for warnings and 2 for errors (the loggers
//  are allowed to raise an exception if that happens).
//
