Re: [aspectj-users] aspectJ with packaged classes
|
Maybe you're going wrong at step 2 below. You can run as a regular
Java application, but you need to select the AspectJ project in the
Run configuration.

Hi Matt,
Thanks for the help.
I really must be the dumbest person on this list, i still havent been able
to to get it to work :(
Firstly, here is what i dummy code looks like:
HelloWorld.java
---------------------
public class HelloWorld {
public static void main(String[] args) {
callHelloWorld();
}
public static void callHelloWorld() {
System.out.println ("Hello World");
}
}
HelloAspect.aj
----------------------
public aspect HelloAspect {
pointcut callHelloWorld() :
execution(* *(..));
after() : callHelloWorld() {
System.out.println("Hello To You Too!");
}
}
These are in two different projects (only the second file in a AspectJ
project, the first one is a simple java project). I added the helloworld.jar
as a inpath jar in the aspectj project. I also
1) turned on the option to see the info in the Problems view and i see the
info on join-points and
2) tried to run it as a aspectJ application and i can select HelloWorld as
the main class in the configuration.
But, when i execute it - i get only "Hello World". When i put both the
classes in the same project and run it, i get the right result.
What am i doing wrong?!
Thanks,
Anirudh
