[equinox-dev] Re: Eclipse Aspects

Rowan,

If we are lucky, it is indeed simple: When using aspect bundles the aop.xml file always has to be on the bundle classpath, not in the META-INF directory.
According to your config.ini it has to be in a package org.aspectj. You also could put it into hooktest if you modify config.ini (org.aspectj.weaver.loadtime.configuration=hooktest), but I would not do that (Best practice: Use always one and the same package).

Give it a try and let me know ...

Heiko

Your aop.xml has to be in a org.aspectj package, not in the META-INF directory.
It always has to be on the bundle classpath and must match a package

Heiko,

I'm sure you are right and we can crack this. I am also sure it is
something simple that I have missed.

Anyway, attached is a zip file of src, manifest files and an aop.xml.
Also in there is my config.ini and a text file 'screenshot' of the
output of doing an 'ss' in the equinox console.

When I install simplebundle and simple-aspects in equinox and start
simplebundle I get this on the console:

osgi> start 63
A simple bundle!

When I use aspectj on the commandline with the same jar files I get
this:

aj5 -classpath
simplebundle/simplebundle.jar:simple-aspects/simple-aspects.jar:/opt/aspectj1.6/lib/aspectjrt.jar simple.Simple
advice after Simple constructor
Before Simple println()
A simple bundle!


I saw a thread describing a similar problem on eclipsezone:

http://www.eclipsezone.com/eclipse/forums/m92227380.html

Martin Lippert answered (in reply 5) saying:
Just implement your aspect inside a bundle, define the aop.xml file and
"Eclipse-SupplementBundle: *" in the manifest. Thats it.

mmmmm.

Annoyingly the original poster said the problem was solved but didn't
say what the solution was!

I really appreciate you taking the time to help me on this.

Rowan
