|
|---|
| 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 an Enterprise Application archive.</p>
|
|---|
| 15 | <p>(The Ear task is a shortcut for specifying the particular layout of a EAR file.
|
|---|
| 16 | The same thing can be accomplished by using the <i>prefix</i> and <i>fullpath</i>
|
|---|
| 17 | attributes of zipfilesets in a Zip or Jar task.)</p>
|
|---|
| 18 | <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 Ear task.</p>
|
|---|
| 19 |
|
|---|
| 20 | <p><b>Please note that the zip format allows multiple files of the same
|
|---|
| 21 | fully-qualified name to exist within a single archive. This has been
|
|---|
| 22 | documented as causing various problems for unsuspecting users. If you wish
|
|---|
| 23 | to avoid this behavior you must set the <code>duplicate</code> attribute
|
|---|
| 24 | to a value other than its default, <code>"add"</code>.</b></p>
