Leiningen war plugin

This is a dead and unsupported project. Developers who are new to clojure web development are recommended to try the excellent lein-ring plugin. If you are mixing Clojure with servlets then the lein-servlet plugin should fit your needs.

Old Readme

This plugin creates standard war files for use with java web application servers and is not useful when developing for the Google App Engine.

This plugin is available at http://clojars.org/

:dev-dependencies [[uk.org.alienscience/leiningen-war "0.0.13"]]

An example application using the plugin is at: http://github.com/alienscience/compojure-war-example.

The best place for discussion and support is the Clojure web development google group: http://groups.google.com/group/clojure-web-dev

This plugin adds three commands to leiningen:

lein web-xml

Create a web.xml file if one does not already exist. For most non-trivial applications this file will need to be edited manually.

By default the file is created in src/web.xml but this can be overidden by setting :webxml in your :war configuration in project.clj.

The servlet class is assumed to be the first entry in the :aot setting given in project.clj.

lein uberwar

Create a war file containing the following directory structure:

destination                   default source              project.clj 
----------------------------------------------------------------------------        
WEB-INF/web.xml               src/web.xml                 :war {:webxml}
WEB-INF/classes               classes                     :compile-path 
WEB-INF/lib                   lib                         :library-path
/                             src/html                    :war {:web-content}
WEB-INF/classes               resources                   :resources-path
WEB-INF/classes               src                         :source-path

Artifacts listed in :dev-dependencies will not copied into the war file. The name of the war file defaults to $PROJECT-$VERSION.war, however, it can be overridden by setting :war :name in project.clj.

lein war

This command does not include dependencies in the war file and is intended for cases where the servlet container classpath is setup manually.

Create a war file containing the following directory structure:

destination                 default source         project.clj 
---------------------------------------------------------------------        
WEB-INF/web.xml             src/web.xml            :war {:webxml}
WEB-INF/classes             classes                :compile-path 
/                           src/html               :war {:web-content}
WEB-INF/classes             resources              :resources-path
WEB-INF/classes             src                    :source-path

Simple Example

(defproject example "0.0.1"
  :dependencies [[org.clojure/clojure "1.2.0"]
                 [org.clojure/clojure-contrib "1.2.0"]]
  :dev-dependencies [[uk.org.alienscience/leiningen-war "0.0.12"]])

lein war will create a war file with the following structure:

WEB-INF/
WEB-INF/web.xml   <--- taken from src/web.xml
WEB-INF/classes   <---- taken from classes
index.html        <---- taken from src/html/index.html

lein uberwar will create a similar directory structure with the addition:

WEB-INF/lib       <----  taken from lib

Overiding Defaults

(defproject example "0.0.1"
  :dependencies [[org.clojure/clojure "1.2.0"]
                 [org.clojure/clojure-contrib "1.2.0"]]
  :dev-dependencies [[uk.org.alienscience/leiningen-war "0.0.12"]]
  :war {:webxml "war/example.xml"
        :web-content "html"}
  :compile-path  "build"
  :library-path  "libs"
  :resources-path "war/resources")

lein war will create a war file with the following structure:

WEB-INF/
WEB-INF/web.xml           <--- taken from war/example.xml
WEB-INF/classes           <---- taken from build
index.html                <---- taken from html/index.html
WEB-INF/classes/templates <---- taken from war/resources/templates

lein uberwar will create a similar directory structure with the addition:

WEB-INF/lib               <----  taken from libs

War name

The default filename used for the .war file is $PROJECT-$VERSION.war. You can change this by specifying the :name key in your :war configuration in project.clj. Don't forget to include ".war" on the end of the name.

Something went wrong with that request. Please try again.
