When we copy the war file to deployments folder, JBoss starts the deployment and we see a file named "isDeploying". During deployment, the application is started as well. At one point of time the "isDeploying" file disappears and file named "deployed" appears.
When the application is being deployed and starting up , what particular response does jboss monitor so that it considers the application as deployed?
It will initialize servlets and filters, create any @Startup EJBs and so on. Everything that the spec requires it to do on startup.
