title: How to print a message in broker log
body: <p>I've been searching on internet and ESQL/WebSphere MessageBroker documentations, to find a way of printing a variable's value so that i can trace it in Broker Logs. Like System.out.println() in java.</p>
  
  <p>I can't debug the messageflow because of some technical issues, so could you please suggest me how to do it or any workarounds.</p>
