I have created and loaded WAR files for Web Applications on my Tomcat 4.1.27 web container.
I have also heard about EAR (Enterprise Archive) file and was wondering if I have the correct definition. On one of my Google searches it says: EAR files contain JAR files and WAR files and another says it is used for packaging one or more modules into a single archive. Module is a web application?? I assume an EAR file can contain many JAR and WAR files wrapped into one file (EAR)? Another way of looking at it is if I have for example 3 WAR files, I can put all 3 in an EAR file?
What you say is correct: an EAR can contain multiple JAR and WAR files. Note that you cannot deploy EAR files on Tomcat. Tomcat is a servlet and JSP container on which you can deploy WAR files. For EAR files, you need a full Java EE container.
