I have a web app running on remote server. Each time I make small modification I need to upload about 18MB. It's very annoying, as often I modify one line in single java file, and again have to upload whole WAR, what takes about 10mins.
When I've used Tomcat with workers, my WARs were extracted into web-app dirs, where I could freely exchange jsp/class files. For sure it's possible in jboss too, but where? Some hints would be appreciated.
Deploy your war as an exploded directory (http://wiki.jboss.org/wiki/Wiki.jsp?page=ExplodedDeployment). Then, if you replace a class file, touch the web.xml file. If you change a jsp file, the change will be picked up automatically (unless you have turned the jsp update scan off).
