|
|---|
| 12 | <h3>Description</h3>
|
|---|
| 13 | <p>An extension of the <a href="jar.html">Jar</a> task with special
|
|---|
| 14 | treatment for files that should end up in the
|
|---|
| 15 | <code>WEB-INF/lib</code>, <code>WEB-INF/classes</code> or
|
|---|
| 16 | <code>WEB-INF</code> directories of the Web Application Archive.</p>
|
|---|
| 17 | <p>(The War task is a shortcut for specifying the particular layout of a WAR file.
|
|---|
| 18 | The same thing can be accomplished by using the <i>prefix</i> and <i>fullpath</i>
|
|---|
| 19 | attributes of zipfilesets in a Zip or Jar task.)</p>
|
|---|
| 20 | <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.</p>
|
|---|
| 21 |
|
|---|
| 22 | <p><b>Please note that the zip format allows multiple files of the same
|
|---|
| 23 | fully-qualified name to exist within a single archive. This has been
|
|---|
| 24 | documented as causing various problems for unsuspecting users. If you wish
|
|---|
| 25 | to avoid this behavior you must set the <code>duplicate</code> attribute
|
|---|
| 26 | to a value other than its default, <code>"add"</code>.</b></p>

|

| 168 | <p>Assume the following structure in the project's base directory:</p>
|
|---|
| 169 | <pre>
|
|---|
| 170 | thirdparty/libs/jdbc1.jar
|
|---|
| 171 | thirdparty/libs/jdbc2.jar

|
|---|
| 176 | src/graphics/images/gifs/small/logo.gif
|
|---|
| 177 | src/graphics/images/gifs/large/logo.gif
|
|---|
| 178 | </pre>
|
|---|
| 179 | then the war file <code>myapp.war</code> created with
|
|---|
| 180 | <pre>
|
|---|
| 181 | <war destfile="myapp.war" webxml="src/metadata/myapp.xml">

|
|---|
| 189 | prefix="images"/>
|
|---|
| 190 | </war>
|
|---|
| 191 | </pre>
|
|---|
| 192 | will consist of
|
|---|
| 193 | <pre>
|
|---|
| 194 | WEB-INF/web.xml
|
|---|
| 195 | WEB-INF/lib/jdbc2.jar
|
|---|
| 196 | WEB-INF/classes/com/myco/myapp/Servlet.class

|
|---|
| 202 | </pre>
|
|---|
| 203 | using Ant's default manifest file. The content of
|
|---|
| 204 | <code>WEB-INF/web.xml</code> is identical to
|
|---|
| 205 | <code>src/metadata/myapp.xml</code>.
|
|---|
| 206 |
|
|---|
| 207 | We regulary receive bug reports that this task is creating the WEB-INF
|
|---|
| 208 | directory, and thus it is our fault your webapp doesn't work. The cause
|
|---|
| 209 | of these complaints lies in WinZip, which turns an all upper-case
|
|---|
| 210 | directory into an all lower case one in a fit of helpfulness. Please check that
|
|---|
| 211 | jar xvf yourwebapp.war shows the same behaviour before filing another
|
|---|
| 212 | report.
