WAR vs EAR for web application with no EJB?

servlets

deployment

I have a Java EE web application that does not make use of EJBs. I am targeting Jetty/Tomcat for deployment some of the time and thus need a WAR packaging. However, I am also target JBoss and Websphere some of the time.

My understanding is that full-blown Java EE application servers can take either EAR or WAR formats. When would I use one over the other and why? I understand they are both standard compressed file formats and I have read 10 different snippets that try to explain them (including this one), but am no closer to understanding the pros and cons of each.

If you have only web modules - use WAR file. If you have different Java EE modules - use EAR. Though you can deliver only web modules in EAR - there is no point in doing this (and you will need to do more complex deployment configuration)
