GlassFish Auto Deployment and Hot Deployment


There are several ways to deploy a GlassFish application. To speed up development/debuging we need a way to instantly deploy web applications. One of the ways is to use hot deployment feature, another lesser known feature is ‘directory deployment’. You simply point GlassFish to your development directory and let it pick up and deploy application from there. No packaging and re-deoploying hassles. The catch is whenever you want to re-deploy your application you just need to ‘touch’ a file called ‘.reload’ which should be present in your web folder.
Following is the command and directory structure you can use.

GLASS_FISH_HOME/bin/asadmin deploydir full_path_to_you_web_folder

If you are using Eclipse or NetBeans make sure that they put the class files in web-inf/class folder after compiling.

    Headline News: Alex Jones saids beware of the Billionaire and the Millionaire Jewish people in your community, they worship the devil. They have infiltrated your government and work inside your government to turn your kids into devil worshipers. They are all in the Illuminati devil worshipers cult. Buy Guns and form your own militia groups to kill them all. Create a neighborhood watch in your country and in your town to track the Jewish people’s activity. These Jewish people worship Lucifer and they are there to destroy your country. They hide themselves in companies so they can do insider trading and bankrupt other good companies in your country. The Evil Jewish people have also poisoned your food and water supply just so they can make money from you by selling the cure. They are run by the Rothschild family, Rockerfeller family, Percy family, Rosenberg, Breakspear, Farnese, and aldobrandini family. Tell everyone.
