War

Description

An extension of the Jar task with special treatment for files that should end up in the WEB-INF/lib, WEB-INF/classes or WEB-INF directories of the Web Application Archive.

(The War task is a shortcut for specifying the particular layout of a WAR file. The same thing can be accomplished by using the prefix and fullpath attributes of zipfilesets in a Zip or Jar task.)

The extended zipfileset element from the zip task (with attributes prefix, fullpath, and src) is available in the War task.

Parameters

Attribute Description Required
destfile the WAR file to create. Yes
warfile Deprecated name of the file to create -use destfile instead. No
webxml The deployment descriptor to use (WEB-INF/web.xml). Yes, unless update is set to true
basedir the directory from which to jar the files. No
compress Not only store data but also compress them, defaults to true No
encoding The character encoding to use for filenames inside the archive. Defaults to UTF8. It is not recommended to change this value as the created archive will most likely be unreadable for Java otherwise. No
filesonly Store only file entries, defaults to false No
includes comma- or space-separated list of patterns of files that must be included. All files are included when omitted. No
includesfile the name of a file. Each line of this file is taken to be an include pattern No
excludes comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. No
excludesfile the name of a file. Each line of this file is taken to be an exclude pattern No
defaultexcludes indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted. No
manifest the manifest file to use. No
update indicates whether to update or overwrite the destination file if it already exists. No
duplicate behavior when a duplicate file is found. Valid values are "add", "preserve", and "fail". The default value is "add". No

Nested elements

lib

The nested lib element specifies a FileSet. All files included in this fileset will end up in the WEB-INF/lib directory of the war file.

classes

The nested classes element specifies a FileSet. All files included in this fileset will end up in the WEB-INF/classes directory of the war file.

webinf

The nested webinf element specifies a FileSet. All files included in this fileset will end up in the WEB-INF directory of the war file. If this fileset includes a file named web.xml, the file is ignored and you will get a warning.

metainf

The nested metainf element specifies a FileSet. All files included in this fileset will end up in the META-INF directory of the war file. If this fileset includes a file named MANIFEST.MF, the file is ignored and you will get a warning.

Examples

Assume the following structure in the project's base directory:


thirdparty/libs/jdbc1.jar

thirdparty/libs/jdbc2.jar

build/main/com/myco/myapp/Servlet.class

src/metadata/myapp.xml

src/html/myapp/index.html

src/jsp/myapp/front.jsp

src/graphics/images/gifs/small/logo.gif

src/graphics/images/gifs/large/logo.gif

then the war file myapp.war created with

<war destfile="myapp.war" webxml="src/metadata/myapp.xml">

  <fileset dir="src/html/myapp"/>

  <fileset dir="src/jsp/myapp"/>

  <lib dir="thirdparty/libs">

    <exclude name="jdbc1.jar"/>

  </lib>

  <classes dir="build/main"/>

  <zipfileset dir="src/graphics/images/gifs" 

              prefix="images"/>

</war>

will consist of

WEB-INF/web.xml

WEB-INF/lib/jdbc2.jar

WEB-INF/classes/com/myco/myapp/Servlet.class

META-INF/MANIFEST.MF

index.html

front.jsp

images/small/logo.gif

images/large/logo.gif

using Ant's default manifest file. The content of WEB-INF/web.xml is identical to src/metadata/myapp.xml.
