Re: [aspectj-users] Constructor join point
|
Eric is mostly there. If you are using a precompiled aspect that is in
a .jar file then you can use the -aspectpath option on your ajc
command-line (in Eclipse, do it on the AspectJ preferences).
If your aspect is compiled separately and you want to weave it into
your .jar then you need to include the .jar by specifying the -inpath
option when using ajc. This option will open up the .jars and compile
your aspects into the extracted .class files. It is then important that
you run the expanded weaved .class byte code files and NOT the original
.jar, I tend to use the -outjar option as well to bundle things up
again after ajc has done the business.
If it's still not working then, if you are using Eclipse, check that
your pointcuts are definitely selecting the places you think they are.
Actually, it's best to check this first if possible :-)
Cheers,
Russ

I have a aspect that traces constructors calls, like this:
public aspect ConstructorAspect{
pointcut contructorExec() : execution(*.*.new(..)) &&
!within(ConstructorAspect);
before() : contructorExec(){
System.out.println( "Constructor executed" );
}
}
When I weave it into a pre-compiled .jar file and run the
application, nothing is printed. What is wrong?
Are you sure, that the jar file is actually woven? You have to put it
into your ASPECTPATH.
