Hi
It should give you some hints with respect to what it is weaving and not,
and why.

I added, Xlint.properties. The result is there are a little bit less logs

Subject: Réf. : RE: Réf. : Re: Re :[aspectj-users] aspect on a java API
class
Thank you for your help,
I tried this, but there is not even trace of the weaving of BigDecimal.
It is a real mystery for me, so I give all the code :
Here is my aop.xml :
<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD 1.5.0//EN"
"http://www.eclipse.org/aspectj/dtd/aspectj_1_5_0.dtd";>
<aspectj>
<weaver options="-Xset:weaveJavaPackages=true -proceedOnError
-Xlintfile:META-INF/Xlint.properties -showWeaveInfo -verbose -debug">
<exclude within="org.apache.commons.logging..*"/>
<include within="test.aop.beans..*"/>
<include within="java..*"/>
</weaver>
<aspects>
<aspect name="test.aop.AppAspect"/>
</aspects>
</aspectj>
Here is my Aspect :
@Aspect
public class AppAspect {
@After("execution(* java.math.BigDecimal.valueOf(..))")
public void afterBigDecimal(JoinPoint jp) {
System.out.println("grouik BigDecimal");
}
@After("execution(* test.aop.beans.*.copyFrom(..))")
public void afterBeans(JoinPoint jp) {
System.out.println("grouik beans");
}
}
Here is my test :
@Test
public void getAndSetOnArrayList() throws Exception {
System.out.println("-------- mytest ----------");
client01.copyFrom();
BigDecimal bd = BigDecimal.valueOf(0);
bd = new BigDecimal(5);
}
Here is the resulting log (I cutted the middle) :

Hi
Try: <weaver options="-proceedOnError -Xlintfile:META-INF/Xlint.properties
-showWeaveInfo -verbose -debug"> in you aop.xml file. The check the log
files to see if you class is wowen. ALso remember to include java.math.** in
you includes section of aop.xml

I downloaded the "Last Known Good developer build" :
aspectj-DEVELOPMENT-20080228164011.jar
Because I'm using LTW, I didn't installed it :
I only took the aspectjweaver.jar, uploaded it in my maven repo, and changed
the version in my pom.xml (1.5.4 to DEVELOPMENT-20080228164011).
In my aop.xml, I changed <weaver>...</weaver> by <weaver
options="-Xset:weaveJavaPackages=true">...</weaver>
But when I execute my code, the advise is still not executed...
Did I miss something ?

Weaving of java. and javax. types has been discussed on the list
recently. You need an up to date AspectJ and you need to use a weaver
option to force it to weave those types in addition to normal
configuration info. The Javax one is shown below, the
weaveJavaPackages=true option is what you need.
