[jboss-user] [JBoss AOP] - Dynamic AOP

[sylobsa]

Hi,

I use JBoss AS 4.2.0, JDK 5.0, JBoss AOP 1.5.5.

I have a J2EE application and I'd like to use dynamic AOP on it. I want to aspectize only a few classes, so I annotated those classes with :
@Prepare ("all(this)")

Now I want to compile them.

I added the following lines after class compilation task.

      <taskdef name="aopc" classname="org.jboss.aop.ant.AopC"
  |           classpathref="aop.path"/>
  |  
  |       <aopc compilerclasspathref="aop.path" verbose="true">
  |          <classpath path="${classes.dir}"/>
  |          <src path="${classes.dir}"/>
  |          <include name="**/*.class"/>
  |       </aopc>
  | 
I get an error on a class where there is no annotation at all.

I want to aspectize only the classes where there is @Prepare annotations, and define pointcuts dynamically at runtime using a xxx-aop.xml file in my deploy directory.

Can somebody tell me what I missed and what I must do to make it work ?


Regards
