Wayne,
Probably the easiest way to crack that nut is with the redeployment options available in the server you’re using. For example, when using WebLogic, if you place a file called REDEPLOY in the WEB-INF directory, each time you touch it WebLogic will undeploy and redeploy your application. JBoss looks for you to touch application.xml and does the same thing. Each server is different, but most have the capability. A bit of research should tell you what it is for the one you’re using.
