                   <responsequeue>emailresponse</responsequeue>
               </Request>

             <Request name="cleanEmail">
                   <requestqueue>cleanrequest</requestqueue>
                   <responsequeue>cleanresponse</responsequeue>

For configuring Java applications, it is really recommended to use the build-in Properties functionality. Properties are (singleton) key/value-pairs. They are however stored in a plain-text format rather than XML. More information can be found here: http://download.oracle.com/javase/tutorial/essential/environment/properties.html

In order to structure the properties, the naming convention is to use dotted names. Your properties-file, could thus look like this:

validateEmailRequest.requestQueue = emailrequest
validateEmailRequest.responsQueue = emailresponse
cleanEmail.requestQueue = cleanrequest
cleanEmail.responseQueue = cleanresponse

The above link also provides information about reading and writing the properties.
