Class Log4JLogChute

java.lang.Object
  org.apache.velocity.runtime.log.Log4JLogChute

All Implemented Interfaces:

LogChute

Direct Known Subclasses:

Log4JLogSystem

public class Log4JLogChute

extends Object

implements LogChute

Implementation of a simple log4j system that will either latch onto an existing category, or just do a simple rolling file log. Use this one rather than SimpleLog4JLogSystem; it uses the modern Logger concept of Log4J, rather than the deprecated Categeory concept.

Since:

Velocity 1.5
