Re: [aspectj-users] Load-time weaving issue

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi,

I took the code as-is and set it up to run ltw from the command line.

The only change I made was adding a main method to the SearchService2
class just so that I could 'run' something:

    public static void main(String[] argv) {
      new SearchService2().get("foo",null);
    }

I then ran it:

java -javaagent:/Users/aclement/installs/aspectj170m1/lib/aspectjweaver.jar
test.services.SearchService2
[AppClassLoader@535ff48b] info AspectJ Weaver Version 1.7.0.M1 built

Before search for:foo op:null
test.services.SearchService2.get 2
After search for:foo op:null

The advice was OK (this was with the include="test.services.*" line).
 I changed the include line to:

<include within="test.services.SearchService2"/>

and that also worked.

When you say it doesn't work, what do you see - do you see the aspect
registration in the debug output, but just no weave infos for the
SearchService2 class?  Can you run it successfully the same as I have
run it?

cheers,
Andy
