Re: [aspectj-users] Re: AspectJ with JRockit - Problem with thisJoinPoint

Hello you guys,

Thanks for the help. The -showWeaveInfo flag was really important to understand how AspectJ works with the weblogic server in the LTW.
I solve my two problems. The mistake was that in all changes I made to my aspects, I were not restarting my server, but this is necessary.

I have a doubt about packing the aspects in a jar. Can I do that and simply put the jar in the classpath of my project? This will work ?

Thanks to everyone that helped me,
Luiz

Hi Luiz,

Are you able to describe the actual NoSuchMethodError that you see?

The advice coming out multiple times is no doubt due to advising more places than you think.  If you cannot use the cross references view in eclipse then try specifying the -showWeaveInfo flag in the weaver option section of your aop.xml.  Then on startup the load-time weaver will tell you everywhere it is weaving - and you can check if it is what you expect.

Andy.

Hello again.

Unfortunately, i'm using BEA Workshop so I can't use crosscutting view.
I will try to explain better my situation here.

I'm using load time weaving but I don't understand how it really works. So I think the problem is bigger than a simple problem with thisJoinPoint or something like that.
I make an aop.xml file to set some configurations.
My application server console give me infos identifying my aspects.

In the project i'm trying to use AOP, I have files like Page Flow files with .jpf in the extension. This may be a problem?

That's one thing. The other is that you have a "call" join point.
Which means the advice is executed every time the _running_ program
_calls_ advised methods. So even if you have only 1 advised method, if
it's called in a loop that executes 100 times, you will see 100
messages.
