How are you launching equinox? Are you using the org.eclipse.equinox.launcher jar or using the eclipse.exe or are you starting equinox directly with something like java -jar org.eclipse.osgi.jar?
The reason I ask is because the osgi.framework.extensions property is
processed by the org.eclipse.equinox.launcher jar which sets up the class
loader for the framework (org.eclipse.osgi). The launcher uses the
osgi.framework.extensions property to discover additional jars that should
be placed on the framework class loader's class path.

Hey Martin,
I just recently found this link,
http://wiki.eclipse.org/JDT_weaving_features, which I believe details the
classpath setup code you are referring to (correct me if I am wrong). I
unfortunately still can't get the hook working with the system bundle. Here
is what my config.ini looks like:
osgi.clean=true
osgi.frameworkClassPath=file
\:/home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/org.eclipse.osgi_3.4.0.v20080605-1900.jar,file
\:/home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/org.eclipse.equinox.weaving.hook_1.0.0.200808061839.jar
osgi.bundles=org.aspectj.runtime_1.6.1.20080703120000,
org.aspectj.weaver_1.6.1.20080703120000,org.eclipse.equinox.weaving.aspectj_1.0.0.200808061839.jar,
org.eclipse.equinox.weaving.hook_1.0.0.200808061839.jar,org.eclipse.equinox.weaving.demo.hello,
org.eclipse.equinox.weaving.demo.hello.aspects
osgi.framework.extensions=org.eclipse.equinox.weaving.hook
aj.weaving.verbose=true
org.aspectj.weaver.showWeaveInfo=true
org.aspectj.osgi.verbose=true
All my bundles are
in /home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld. My
config.ini is
in /home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/Configuration.
I am not sure what else I could be doing wrong at this point and I must be
close to figuring out this problem :)

Hi Daniel,
if I remember this correctly you need to put the org.eclipse.osgi bundle
AND the framework extension bundles on the classpath if you start the
runtime the way you do it.
(The exception you mention indicates that the framework extension is not
installed correctly.)
HTH,

> I have been trying very hard to get the Equinox Aspects Hello World
project run correctly outside of Eclipse, just using a custom config.ini
and the Equinox shell. I believe the last thing holding me up is that the
weaving.hook fragment bundle is not hooking into the system bundle. I have
all the files from the plugins folder of the Hello World demo in the same
folder as my system bundle and I have the hello and hello.aspects bundle in
the same folder. My config.ini is in the ./configuration folder. It is a
simple setup and there shouldn't be a co-location problems with the hook
bundle. I'll post my config.ini below.
