If you choose to use Apache Maven (I suggest this ;) ) you must add in your root project directory pom.xml file (POM). POM is a descriptor about Maven lifecyle of your application. You can see all info about how to install Maven and create a pom.xml here: http://maven.apache.org/ If you choose to use Apache Ant you must add a build.xml file. Build.xml is a procedures file about all targets to do to create your package. Here you can see how to install Ant and create your own build.xml file: http://ant.apache.org/ View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4215300#...
