Logging of messages sent with Spring WS client

When sending messages with Spring WS client, observing of actual sent and received messages is often required. To set the logging level, add the following lines in log4j.properties:

log4j.logger.org.springframework.ws.client.MessageTracing.sent=TRACE
log4j.logger.org.springframework.ws.client.MessageTracing.received=TRACE

Here's what you might observe in the logs:

2012-08-02 12:31:49,615 TRACE [org.springframework.ws.client.MessageTracing.sent] - Sent request [<SOAP-ENV:Envelope...
2012-08-02 12:31:50,581 TRACE [org.springframework.ws.client.MessageTracing.received] - Received response [<env:Envelope
