Re: [aspectj-users] aspectJ with packaged classes

["Anirudh Chandrakant" <anirudh.chandrakant@xxxxxxxxx>]

Hi,

Thanks for that, it makes things a little clearer.

But i am still facing a few problems. Here is what i did:

1. I created a Java project with one class which basically prints 'Hello World'
2. I packaged this into a jar and exported it to a location.
3. I created a AspectJ project with one aspect which prints a message
after the call to the method which prints 'Hello World'.
4. I packaged this as a 'Jar File with AspectJ support' and exported it.
5. When i execute it with the command you have specified, all i can
see is 'Hello World' with no message from the aspect.

I thought there might be something wrong with my code, so i put the
Hello World class in the aspect project. When i ran it, it displayed
the right information.

Am i doing something wrong? Do i need to do something more?

Thanks again,
Anirudh
