| <title>WAR Task</title> |
| </head> |
| |
| <body> |
| |
| <h2><a name="war">War</a></h2> |
| <h3>Description</h3> |
| <p>An extension of the <a href="jar.html">Jar</a> task with special |
| treatment for files that should end up in the |
| <code>WEB-INF/lib</code>, <code>WEB-INF/classes</code> or |
| <code>WEB-INF</code> directories of the Web Application Archive.</p> |
| <p>(The War task is a shortcut for specifying the particular layout of a WAR file. |
| The same thing can be accomplished by using the <i>prefix</i> and <i>fullpath</i> |
| attributes of zipfilesets in a Zip or Jar task.)</p> |
| <p>The extended zipfileset element from the zip task |
| (with attributes <i>prefix</i>, <i>fullpath</i>, and <i>src</i>) |
| is available in the War task. The task is also resource-enabled |
| and will add nested resources and resource collections to the archive.</p> |
| |
| <p> |
| Before Servlet API 2.5/Java EE 5, a WEB-INF/web.xml file was mandatory in a |
| WAR file, so this task failed if the <code>webxml</code> attribute was missing. |
| As the web.xml file is now optional, the <code>webxml</code> attribute may now |
| be made optional. However, as most real web applications do need a web.xml file, |
| it is not optional by default. The task will fail if the file is not |
| included, unless the <code>needxmlfile</code> attribute |
| is set to <code>true</code>. The task |
| will warn if more than one web.xml file is added to the JAR |
| through the filesets. |
| </p> |
| |
| |
| <p><b>Please note that the Zip format allows multiple files of the same |
| fully-qualified name to exist within a single archive. This has been |
| documented as causing various problems for unsuspecting users. If you wish |
| to avoid this behavior you must set the <code>duplicate</code> attribute |
| to a value other than its default, <code>"add"</code>.</b></p> |

| rerun the task, so the default is to round up. Rounding up may |
| lead to a different type of problems like JSPs inside a web |
| archive that seem to be slightly more recent than precompiled |
| pages, rendering precompilation useless.<br> |

| <h3>Nested elements</h3> |
| |
| <h4>lib</h4> |
| <p>The nested <code>lib</code> element specifies a <a |
| href="../CoreTypes/fileset.html">FileSet</a>. All files included in this fileset will |
| end up in the <code>WEB-INF/lib</code> directory of the war file.</p> |
| |
| <h4>classes</h4> |
| <p>The nested <code>classes</code> element specifies a <a |
| href="../CoreTypes/fileset.html">FileSet</a>. All files included in this fileset will |
| end up in the <code>WEB-INF/classes</code> directory of the war file.</p> |
| |
| <h4>webinf</h4> |
| <p>The nested <code>webinf</code> element specifies a <a |
| href="../CoreTypes/fileset.html">FileSet</a>. All files included in this fileset will |
| end up in the <code>WEB-INF</code> directory of the war file. If this |
| fileset includes a file named <code>web.xml</code>, the file is |
| ignored and you will get a warning.</p> |
| |
| <h4>metainf</h4> |
| <p>The nested <code>metainf</code> element specifies a <a |
| href="../CoreTypes/fileset.html">FileSet</a>. All files included in this fileset will |
| end up in the <code>META-INF</code> directory of the war file. If this |
| fileset includes a file named <code>MANIFEST.MF</code>, the file is |
| ignored and you will get a warning.</p> |
| |
| <h4>manifest, indexjars, service</h4> |
| These are inherited from <a href="jar.html"><jar></a> |
| |
| <h3>Examples</h3> |
| |
| <p>Assume the following structure in the project's base directory:</p> |
| <pre> |
| 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 |
| </pre> |
| then the war file <code>myapp.war</code> created with |
| <pre> |
| <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> |
| </pre> |
| will consist of |
| <pre> |
| 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 |
| </pre> |
| using Ant's default manifest file. The content of |
| <code>WEB-INF/web.xml</code> is identical to |
| <code>src/metadata/myapp.xml</code>. |
| |
| <p>We regulary receive bug reports that this task is creating the WEB-INF |
| directory, and thus it is our fault your webapp doesn't work. The cause |
| of these complaints lies in WinZip, which turns an all upper-case |
| directory into an all lower case one in a fit of helpfulness. Please check that |
| <code>jar xvf yourwebapp.war</code> shows the same behaviour before filing another |
| report.<br/> |
| Winzip has an option allowing all uppercase names (which is off by default!). It can be enabled by: |
| Menu "Options" -> "Configuration", "View" property/tab page, then "General" group box has an option called "Allow all uppercase file names". |
