* have the JNDI java:comp/env namespace setup before any web app component can access this
* namespace.
*

* into the DeploymentInfo.mbeans list so that the JSR77 layer can create the approriate model
* view. The servlet MBean needs to provide access to the min, max and total time in milliseconds.
* Expose this information via MinServiceTime, MaxServiceTime and TotalServiceTime attributes to
* integrate seemlessly with the JSR77 factory layer.

* application/module/web application.xml descriptor. This may be null if war was is not being
* deployed as part of an enterprise application. It also contains the URL of the web
