The administration GUI interface (admin-gui) does not allow the administrator to
reload web applications without doing it manually.
Glassfish has dynamic reloading by touching a .reload file in the
domains/domain1/applications/j2ee-modules/webAppName context root directory.
At first, one could allow the administrator to reload a web application by
clicking a "Reload" link which is next to the "Launch | Redeploy" links at the
same line as the web application in the 'DeployTable.inc'. Dynamic reloading
(touch .reload) should be used since it is currently stable.
