The nullVM is added to the DGEE by inserting the following section within the
<servers> element of the dgeeconf.xml file.
The dgeeconf.xml will need recompiling with the gwmkcfg command.


    <servers>
      ....
      ....
      ....
	  <!-- The null VM -->
	  <class id="400" exe="DGnullVM" min="3" max="5" priority="10" >
		<service function="runWS">/DGEE/VM/nullExec</service>
      </class>
      ....
      ....
      ....
    </servers>
