I have created an aspect within one bundle whose pointcut keys off a method call by an interface in another bundle.
I have done all that is described in the documentation in order to properly set up the aspect, but apparently the aspect isn't being engaged. In fact, in the code I am getting a warning saying that the advice "has not been applied".
My aspect is:
public aspect ServiceGate
{
pointcut serviceCatch(Map<String,String> theMap) :
cflowbelow(execution(void BundleActivator.start(BundleContext))) &&
execution(ServiceResult IAresService.performService(Map<String,String>)) &&
args(theMap);
ServiceResult around(Map<String,String> theMap) : serviceCatch(theMap)
{
System.out.println("A Service was called!");
return(proceed(theMap));
}
}
The manifest for the aspect bundle is below:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Security Bridge
Bundle-SymbolicName: mil.af.ares.aspect.security
Bundle-Version: 1.0.0
Bundle-Activator: mil.af.ares.aspect.security.SecurityActivator
Bundle-Vendor: Self
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Import-Package: mil.af.ares.service.intfc,
org.osgi.framework;version="1.3.0"
Bundle-ActivationPolicy: lazy
Require-Bundle: org.aspectj.runtime;bundle-version="1.6.11";visibility:=reexport
Export-Package: mil.af.ares.aspect.bridge
Eclipse-SupplementBundle: mil.af.ares.service.intfc
and my aop.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<aspectj>
<aspects>
<aspect name="mil.af.ares.aspect.bridge.ServiceGate" />
</aspects>
</aspectj>
This setup follows the documentation for using Equinox Aspects exactly, but for some reason the aspect is not working.
Am I missing something in the setup? I have the weaver working and the hook is properly set up (and the debugger shows the hook code working properly!). I have set up everything else according to the documentation, or at least I am sure that I did. So am I missing something,or have I found a bug in Equinox Aspects. Does it work at all?
If I have found a bug, where do I go to report it? Who do I talk to about problems with this project???
Someone please advise.

Hey Robert!

That the weaver bundle is started is good. Are you sure the framework
hook is configured correctly? For example using this option:
-Dosgi.framework.extensions=org.eclipse.equinox.weaving.hook
There should be something appearing like:
"info Adding AspectJ hooks..."
If that doesn't appear, something is broken before the actual weaving
can happen...
