Cross Project reference [message #63053]

Some clarifactions required using aspectJ and AJDT.

Assume that I two projects:

Project A - AspectJ project that contains only the aspects.
Project B - Is a normal java project.

While writing the aspects in proj.A, my aspects will need to make some
references to project B java files E.g: Load some configuration. How can
this be achieved? I tried by adding the project B to the java build path
(under projects) of the aspectJ project A. Now i can access the classes of
project B in the aspect, but when i run my main class using the aspect-J
load time weaving option - my aspects don't get invoked. My main class
that i run is in the java project B. how can this be achieved ?

Hi Satish,

You need to add Project A to the load-time weaving aspectpath, which is
configured through a tab called "LTW Aspectpath" in the run dialog.

Actually, I am having the same problem. I saw Sian's reply, but I don't
see any such "LTW Aspectpath" in any properties anywhere. I do see an
"AspectJ aspect path" in the project properties, where I can add class
folders. I have added the class folders of the two projects I want to
weave my aspect into, and it looks like the correct classes are being
woven when I run the builder. However, my aspect is never invoked.
Additional help here would be great.

The "LTW Aspectpath" tab is in the run configuration for an "AspectJ
Load-Time weaving application". So, you need to do run > run as and select
the aspectj load-time weaving application configuration to run your
program.

Thanks, Helen. This leads me to the question of how in the world would
I run this in an application server in a production environment???

Hi Don,

The on-line documentation should help explain how you can run this in a
production environment
http://www.eclipse.org/aspectj/doc/released/devguide/ltw.htm l.

Thanks, Helen
