Fixes https://github.com/spring-projects/spring-integration-samples/issues/340 The `LoggingHandler` uses a `org.springframework.integration.handler` category by default. So, the `info` provided for the `loggingChannelAdapter` service activator does not have any effects because `logback.xml` has an `ERROR` for the `org.springframework.integration` category * Use dedicated `wsLog` category in the `LoggingHandler` bean definition to print a server message published to the subscribed web socket clients
