By: Ash
Question:What is the difference between EAR, JAR and WAR file?Answer:
J2EE defines three types of archives:
1. Java Archives (JAR) A JAR file
encapsulates one or more Java classes, a manifest, and a descriptor. JAR files
are the lowest level of archive. JAR files are used in J2EE for packaging EJBs
and client-side Java Applications.
2. Web Archives (WAR) WAR files
are similar to JAR files, except that they are specifically for web applications
made from Servlets, JSPs, and supporting classes.
3. Enterprise
Archives (EAR) â€An EAR file contains all of the components that make up a
particular J2EE application.
