Hi Daniel!
Glad to hear that the weaving extension is running now. But the error
you get is strange, since the weaving demo doesn't do anything with XML
or SAX... Do you have a stack trace for the exception?

I start the weaving.demo.hello though I am met with a java.lang.ClassNotFoundException:
org.xml.sax.helpers.DefaultHandler error.
This error seems easy enough, I download the sax2r2.jar and ran this: java -cp
sax2r2.jar:org.eclipse.osgi_3.4.0.v20080605-1900.jar:org.eclipse.equinox.weaving.hook_1.0.0.200808061839.jar
org.eclipse.core.runtime.adaptor.EclipseStarter -console
For some reason though that does not correct the problem. I get the exact same
error as before when I try to start the weaving.demo.hello bundle. I don't get
it, I have the sax2r2.jar in the same folder as everything else. Am I doing
something wrong again?

When using java -jar command I don't think the -cp option is sometimes ignored
depending on the VM you are using.
You would have to use the "main" class
org.eclipse.core.runtime.adaptor.EclipseStarter to launch Equinox along with the -cp
option to list the org.eclipse.osgi jar and the framework extension jars you want to
include:
java -cp org.eclipse.osgi.jar:<extension.jar>
org.eclipse.core.runtime.adaptor.EclipseStarter -console

I have been starting Equinox directly with java -jar org.eclipse.osgi.jar
-console. I'll investigate the org.eclipse.equinox.launcher, feel free to show
me how you all would use it. Hopefully I can find some documentation on it.
Martin, I tried java -jar org.eclipse.osgi_3.4.0.v20080605-1900.jar -console
-cp org.eclipse.equinox.weaving.hook, but that did not work. I am thinking that
I need to use the launcher that Tom referenced.

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,
-Martin
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.
Config.ini:
osgi.clean=true
org.aspectj.osgi.verbose=true
eclipse.ignoreApp=true
aj.weaving.verbose=true
org.aspectj.weaver.showWeaveInfo=true
osgi.bundles=org.eclipse.equinox.weaving.demo.hello.aspects,
org.eclipse.equinox.weaving.aspectj_1.0.0.200808061839.jar,
org.aspectj.weaver_1.6.1.20080703120000,
org.aspectj.runtime_1.6.1.20080703120000, org.eclipse.equinox.weaving.demo.hello
osgi.framework.extensions=org.eclipse.equinox.weaving.hook
I set the framework extension correctly right? Also, here is how I start the
Equinox shell. If I enter start 3 I get an error,
java.lang.NoClassDefFoundError:
org.eclipse.equinox.service.weaving.IWeavingService
