Programmatic hot deploy with Jetty
- Create the server:
Server jetty = new Server(); - Create a handlerCollection with a ContextHandlerCollection in it:
HandlerCollection hc = new HandlerCollection ();
ContextHandlerCollection contextHandlerCollection = new ContextHandlerCollection();
hc.setHandlers(new Handler[]{contextHandlerCollection});
jetty.setHandler(hc); - Start the server:
server.start(); - Hot deploy your web application:
WebAppContext warWebappContext = new WebAppContext();
//configure it ...
contextHandlerCollection.addHandler(warWebappContext);
warWebappContext.start(); - Hot undeploy your application:
//get the WebAppContext to undeploy...
WebAppContext toUndeploy = getWebAppContextToUndeploy();
//stop it
toUndeploy.stop();
//and remove it from the handler collection
contextHandlerCollection.removeHandler(toUndeploy);In a nutshell, the trick is to use a HandlerCollection for your WebAppContextHandler.

How to change JBoss default port
1. Open the JBoss Folder
2. Goto its Deploy folder.

5. Find the folowing Tag
<Connector port="8080" address="${jboss.bind.address}"…….
6. Change the port number here.
7. Restart the server.
Jboss預設只能以127.0.0.1本機存取,如要改變binding address,啟動時指令如下:
run -c default -Djboss.bind.address=0.0.0.0
