Hi all,

I'm using equinox weaving to do aspect across OSGi bundles.My server is Virgo tomcat. Below exception occured when i start my plan:

Unable to satisfy dependencies of bundle 'org.eclipse.equinox.weaving.aspectj' at version '1.0.0.v20100503': Cannot resolve: org.eclipse.equinox.weaving.aspectj Resolver report: An Import-Package could not be resolved. Caused by missing constraint in bundle <org.eclipse.equinox.weaving.aspectj_1.0.0.v20100503> constraint: <Import-Package: org.eclipse.equinox.service.weaving; version="0.0.0">

http://dev.eclipse.org/mhonarc/lists/ajdt-dev/msg01552.html
https://bugs.eclipse.org/bugs/show_bug.cgi?id=333646
These two websites give some recommendations to fix this problem. But it doesn't work. Anyone can help me with it.

Thx
Kevin

The most likely cause is that your config.ini is not set up properly to load the org.eclipse.equinox.weaving.hook fragment. Try this. Start up with an osgi prompt (use the -console option) and type 'ss'. This will list your bundles and fradments. Do you see the hook fragment? If not, then it is not being loaded properly and you should fix your config.ini. If it is, then something else is the matter.

Hi Andrew

Thank u for ur reply. I follow ur step and org.eclipse.equinox.weaving.hook doesn't load. I have set
osgi.framework.extensions=org.eclipse.equinox.weaving.hook

i have also try to set the start level lower
osgi.bundles=org.eclipse.equinox.weaving.hook@1\:start

But it doesn't work yet. Attachment is my config.ini. Is there any problem

Thx
Kevin

Two things:

1. I don't see any osgi.framework.extensions entry. This is required in order for equinox to know about framework adapters.
2. Things may be different since you're using virgo. You may need to load framework adapters differently.

I've start org.eclipse.equinox.weaving.hook and org.eclipse.equinox.weaving.aspectj successfully by putting jars into virgo\plugins and modifying virgo\configuration\org.eclipse.equinox.simpleconfigurator\bundles.info. Bundles' state list below

id State Bundle
0 ACTIVE org.eclipse.osgi_3.8.1.v20120830-144521
Fragments=1, 2
1 RESOLVED org.eclipse.virgo.kernel.equinox.extensions_3.6.2.RELEASE
Master=0
2 RESOLVED org.eclipse.equinox.weaving.hook_1.0.200.I20130319-1000
Master=0
3 ACTIVE org.eclipse.equinox.weaving.aspectj_1.0.300.I20130319-1000
......
66 RESOLVED org.aspectj.weaver_1.7.3.20130613144500-a
67 RESOLVED org.aspectj.runtime_1.7.3.20130613144500-a
......

I'm sure my aspect bundle started erlier than target bundle. But aspect doesn't work

Hmmm...I wonder if this is a problem with Virgo and how it does classloading differently. I am not familiar with Virgo, so I can't really be sure.

Do you see log messages stating that the weaver and the hooks have been started? If you have logging turned on in your config.ini, you should see that information in the console.
