title: how to move file to error directory and rollback other move with apache camel?
body: <p>First of all: i'm a camel newbie :-)</p>
  
  <p>I want to transfer a file from an input directory to an output directory and do some java stuff.
  If something goes wrong, i want to move the file to an error directory and rollback to move to the output directory.</p>
  
  <p>This is my route in java dsl:</p>
  
  <pre><code>onException(Exception.class).handled(true).to("file://C:/temp/camel/error");
  from("file://C:/temp/camel/in?delete=true").to("file://C:/temp/camel/out").bean(ServiceBean.class, "callWebservice");
  </code></pre>
  
  <p>If an error is thrown in the ServiceBean, the file is copied to the error folder, but it also stays in the out directory.</p>
  
  <p>What is the best way to rollback?</p>
  
  <p>Thanks</p>
