Re :[aspectj-users] aspect on a java API class

["Kunal Pathak" <kunalpathak2006@xxxxxxxxxxxxxx>]

Hi Laurent ,

I tried a "without annotation" approach for load time weaving and i could execute an advice code for the joinpoint you mentioned. Can you please try out using simple aj command or you want to use the annotation? I mean I don't think it's the problem due to annotation, but still want to know. 

Thanks,
Kunal.

  Hi all,
  
  
  
  I am (still) trying to put a joinpoint on a java API class : java.math.BigDecimal
  
  I try to do it with load time weaving LTW (with a JavaAgent)
  
  
  
  My aspect is like this :
  
  @Aspect
  
  public class AppAspect {
  
      @After("execution(* java.math.BigDecimal.valueOf(..))")
  
                          public void afterBigDecimal(JoinPoint jp) {
  
                                  System.out.println("grouik BigDecimal");
  
      }
  
  }
  
  
  
  And, because I know it is normally not authorized to do it,
  
  I bypass the loading of the BigDecimal of the rt.jar, by bootloading an extracted java.math.BigDecimal.
  
  I do it by adding in the JVM parameters -Xbootclasspath/p:"D:...	arget	est-classes	emp"
  
  where ...	emp contains javamathBigDecimal.class
  
  
  
  But when I execute this, the advise is not executed...
  
  
  
  Is the bypass a good solution ? If yes, why does it not working ? If no, is there another way ?
  
  
  
  Thanks in advance.
