A <a href="http://en.wikipedia.org/wiki/WAR_%28Sun_file_format%29"><code>.war</code> file</a> has a specific structure in terms of where certain files will be. Other than that, yes, it's just a <code>.jar</code>.

A <code>.war</code> file is a Web Application Archive which runs inside an application server while a <code>.jar</code> is Java Application Archive that runs a desktop application on a user's machine.

blocks|key|910977|text|war文件是一种特殊的jar文件，用于打包web应用程序，以便在应用程序服务器上轻松部署。war文件的内容必须遵循定义的结构。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|910978|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

A war file is a special jar file that is used to package a web application to make it easy to deploy it on an application server. The content of the war file must follow a defined structure.

blocks|key|911049|text|.jar和.war都是压缩的归档文件。两者都可以有可选的META-INF/MANIFEST.MF清单文件，该文件包含版本控制等信息，以及将执行它的JVM的类路径和主类等指令性属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|911050|servlet文件-+Web应用程序归档文件旨在在“servlet容器”中执行，可能包括其他jar文件(在WEB-INF/lib目录)、编译类(在WEB-INF/classes+(servlet也在那里))、.jsp文件、图像、文件等。所有的WAR内容都在那里，以便创建一个独立的模块。|911051|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

.jar and .war are both zipped archived files.
Both can have the optional META-INF/MANIFEST.MF manifest file which hold informative information like versioning, and instructional attributes like classpath and main-class for the JVM that will execute it.

.war file - Web Application Archive intended to be execute inside a 'Servlet Container' and may include other jar files (at WEB-INF/lib directory) compiled classes (at WEB-INF/classes (servlet goes there too)) .jsp files images, files etc. 
All WAR content that is there in order to create a self-contained module.

blocks|key|694701|text|war和jar是java文件的归档文件。war是web归档文件，它们在web服务器上运行。jar是java归档文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|694702|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

war and jar are archives for java files. war is web archive and they are running on web server. jar is java archive.

blocks|key|694837|text|基本上都是压缩的归档文件。war用于具有特定目录结构的web应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|694838|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Basicly both compressed archives. war is used for web application with a specific directory structure.

blocks|key|911198|text|JAR文件扩展名是.jar，它是在命令提示符下使用jar命令创建的(类似于执行javac命令)。通常，JAR文件包含与Java相关的资源，如库、类等。etc.JAR文件与winzip文件类似，不同之处在于Jar文件是平台独立的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|911199|WAR文件只是一个JAR文件，但只包含与Web相关的Java文件，如Servlets、JSP、HTML。|911200|要执行WAR文件，需要Web服务器或Web容器，例如Tomcat、Weblogic或Websphere。要执行JAR文件，简单的JDK就足够了。|911201|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

A JAR file extension is .jar and is created with jar command from command prompt (like javac command is executed). Generally, a JAR file contains Java related resources like libraries, classes etc.JAR file is like winzip file except that Jar files are platform independent.

A WAR file is simply a JAR file but contains only Web related Java files like Servlets, JSP, HTML.

To execute a WAR file, a Web server or Web container is required, for example, Tomcat or Weblogic or Websphere. To execute a JAR file, simple JDK is enough.

blocks|key|695035|text|JAR文件允许打包多个文件，以便将其用作库、插件或任何类型的应用程序。另一方面，WAR文件仅用于web应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|695036|JAR可以用任何所需的结构创建。相比之下，WAR有一个预定义的结构，包含WEB-INF和META-INF目录。|695037|JAR文件允许Java+Runtime+Environment+(JRE)在单个请求中部署整个应用程序，包括类和相关资源。另一方面，WAR文件允许轻松地测试和部署web应用程序。|695038|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

JAR files allow to package multiple files in order to use it as a library, plugin, or any kind of application. On the other hand, WAR files are used only for web applications. 

JAR can be created with any desired structure. In contrast, WAR has a predefined structure with WEB-INF and META-INF directories. 

A JAR file allows Java Runtime Environment (JRE) to deploy an entire application including the classes and the associated resources in a single request. On the other hand, a WAR file allows testing and deploying a web application easily.

What is the difference between a <code>.jar</code> and a <code>.war</code> file? 
Is it only the file extension or is there something more?
