Class LogUtils

java.lang.Object

org.apache.cxf.common.logging.LogUtils

public final class LogUtils
extends Object

A container for static utility methods related to logging. By default, CXF logs to java.util.logging. An application can change this. To log to another system, the application must provide an object that extends AbstractDelegatingLogger, and advertise that class via one of the following mechanisms:

• Create a file, in the classpath, named META-INF/cxf/org.apache.cxf.Logger. This file should contain the fully-qualified name of the class, with no comments, on a single line.
• Call setLoggerClass(Class) with a Class reference to the logger class.

CXF provides Slf4jLogger to use slf4j instead of java.util.logging.
