28 | * @version $Revision: 1.1 $ | |
29 | * <p>Below is the annotation that signifies this class is "prepared" under JBossAop. This is used in | |
30 | * conjunction with a special jboss-aop.xml (supplied by JBossCache). In addition, this is JDK1.4 style, | |
31 | * so a annoc Ant build target is needed to pre-compile it.</p> | |
32 | * <p>To use this approach, just apply this line to your pojo and run annoc (and possibly aopc).</p> | |
