Difference between .jar .war & .ear

[ajagania]

Hello EveryBody,

Please tell me what is the difference between .jar .war & .ear file and when we should use which.

Its very much confusing for me.

Any pointers on this will be greatly appreciated.

Thanks & Regards,

An EAR(Enterprise archive) is a top-level container which contains modules like:
EJB modules, web modules, application client modules etc.

A WAR file is for a Web application deployed to a servlet/JSP engine. It\'s got a WEB-INF directory, where the deployment descriptor web.xml sits. Underneath that are directories WEB-INF/classes and WEB-INF/lib, where web application classes and JARs live, respectively.

An EAR file is an enterprise application deployed to an application server like WebLogic, WebSphere, JBOSS, etc. It might contain WARs, JARs, etc.

EAR = WAR(Web module) + JAR(can be EJB module or application client module)
