2.JAR files can be created with any format and directory of your choice; whereas WAR files are created from Servlets. 3.They have a specific format; they have specific directories and files. The WAR files have a WEB-INF directory, WEB-INF/lib directory, WEB-INF/web.xml, and WEB-INF/classes directory.
4.The acronym of “JAR” files is “Java Archive” files; whereas the acronym of “WAR” files is “Web Application Archive” files.
5.The JAR files are packaged with a .jar extension; whereas WAR files are packaged with a .war extension.
6.EJB modules are packaged as JAR files. This module contains an EJB descriptor and Java beans class files; whereas web modules are packaged as WAR files which contain JSP files, Servlet class files, supporting files, GIF, and HTML.
