When I am writing some JSP or web app or similar I am a real fan of being able to edit a file and the changes get picked up by the application server immediately and I can see my changes quickly. Tomcat has done this for ages but now I need to develop in JBoss EAP and it didn’t seem to allow this.<\/p>\n

To deploy to a standalone instance of JBoss one way is to place your war file in:<\/p>\n

\\jboss-eap-6.1\\standalone\\deployments<\/p>\n

\"\"<\/a>

Another is to create a directory which contains your exploded war, so something likeBut to make this deploy create a text file in the deployments directory called “myapp.war.deployed”. This will make JBoss realize it is an exploded deploy.<\/p>\n

Finally you need to start up JBoss and go to the management console and look for “Deployment Scanners”:<\/p>\n

\"\"<\/a>

Once you have got to the above screen click on the “Edit” button in “Deployment Scanners” and enable “Auto-deploy exploded”, it is disabled by default. The “Scan interval (ms)” is how many milliseconds you need to wait until JBoss notices you have changed the file.<\/p>\n

Now you can edit files in “\\standalone\\deployments\\myapp.war” and almost instantly they will be live.<\/p>\n

One advantage of this is that the directory “myapp.war” can then be zipped up to a file called “myapp.war” and deployed as a genuine war file.<\/p>\n","protected":false},"excerpt":{"rendered":"
