## org.apache.axis.handlers
Class LogHandler

    java.lang.Object
      org.apache.axis.handlers.BasicHandler
          org.apache.axis.handlers.LogHandler

All Implemented Interfaces:
  Handler, java.io.Serializable

public class LogHandler
extends BasicHandler

A simple Handler which logs the request and response messages to either the console or a specified file (default "axis.log"). To use this, deploy it either in both the request and response flows (global, service, or transport) or in just the response flow. If deployed in both places, you'll also get an elapsed time indication, which can be handy for debugging.

Field Detail

### log

    protected static org.apache.commons.logging.Log log

Constructor Detail

### LogHandler

    public LogHandler()

Method Detail

### init

    public void init()

  Description copied from class: `BasicHandler`
  Stubbed-out methods. Override in your child class to implement any real behavior. Note that there is NOT a stub for invoke(), since we require any Handler derivative to implement that.

  Specified by:
    `init` in interface `Handler`
  Overrides:
    `init` in class `BasicHandler`

### invoke

    public void invoke(MessageContext msgContext)
                throws AxisFault

  Description copied from interface: `Handler`
  Invoke is called to do the actual work of the Handler object. If there is a fault during the processing of this method it is invoke's job to catch the exception and undo any partial work that has been completed. Once we leave 'invoke' if a fault is thrown, this classes 'onFault' method will be called. Invoke should rethrow any exceptions it catches, wrapped in an AxisFault.

  Parameters:
    `msgContext` - the `MessageContext` to process with this `Handler`.
  Throws:
    `AxisFault` - if the handler encounters an error

### onFault

    public void onFault(MessageContext msgContext)

  Description copied from interface: `Handler`
  Called when a subsequent handler throws a fault.

  Specified by:
    `onFault` in interface `Handler`
  Overrides:
    `onFault` in class `BasicHandler`
